HYDROLOGY AND QUALITY OF GROUND WATER IN

NORTHERN THURSTON COUNTY, WASHINGTON

By B.W. Drost, G.L. Turney, N.P. Dion, and M.A. Jones

ABSTRACT

Northern Thurston County is underlain by as much as 1,800 feet of unconsolidated deposits of Pleistocene Age that are of glacial and nonglacial origin. Iterpretation of approximately 1,140 drillers' logs led to the delineation of seven major geohydrologic units, four of which are signif icant aquifers.

Precipitation ranges from about 35 to 65 inches per year across the study area. Estimates of recharge indi cate that the ground-water system of the Ground Water Management Area (GWMA), a subset of the study area, receives an average of about 28 inches per year. Ground water generally moves toward marine water bodies and to major surface drainage channels.

At least 33,000 acre-feet per year of ground water dis charges as springs from the GWMA. Approximately 21,000 acre-feet of water was withdrawn from the ground-water system of the GWMA through wells in 1988. Total ground-water use in the GWMA in 1988 was approximately 37,000 acre-feet. About 16,000 acre-feet of water that discharges naturally through springs was used together with water withdrawn by wells for domestic supply, agricultural, commercial, industrial, institutional, and aquaculture and livestock uses.

Generally, the chemical quality of the ground water was good and 94 percent of the water samples were classi fied as soft or moderately hard. Of the few water-quality problems encountered, the most widespread anthropo genic problem appeared to be seawater intrusion. How ever, a comparison with data from 1978 indicated that the degree and extent of intrusion had not changed signifi cantly since that time. Agricultural activities may be responsible for the presence of nitrate in ground waters at some individual wells, but septic tanks in areas of high housing density are likely responsible for elevated nitrate concentrations near the Cities of Lacey and Tumwater.

The close correlation of nitrate concentrations with deter gent concentrations supports the theory that the nitrate originates in septic systems, the only likely source of the detergents.

Most water-quality problems in the study area, how ever, are due to natural causes. Iron concentrations are as large as 21,000 micrograms per liter, manganese concen trations are as large as 3,400 micrograms per liter, and connate seawater is present in ground water in the south ern part of the study area.

REVISION NOTE

The original version of the report was published in 1994. During a subsequent phase of study, while applying a numerical model to simulate the ground-water flow sys tem, errors were discovered in the original report. These errors resulted from the method used to assign geohydro logic units to wells.

Geohydrologic unit assignments have been reevalu- ated for all wells. This has resulted in changes to the surficial geologic map, unit top and thickness maps, geo hydrologic sections, and water-level maps, as well as revised statistics for hydraulic conductivity, water use, common constituents by geohydrologic unit, and trilinear diagrams.

Most of the data presented in this report were col lected in 1988 and 1989. The discussions and conclusions in this report are based on the original field data and repre sent our knowledge of the hydrology and quality of the ground water at that time.

INTRODUCTION

Demand for water in the northern part of Thurston County, Wash., has increased steadily in recent years because of rapid growth in population and residential development. Thurston County lies at the southern end of Puget Sound in western Washington, and is bounded at the north by a coastline of numerous marine inlets. The north ern part of the county consists of thick deposits of glacial origin, including widespread deposits of sand and gravel at land surface.

Describe the general chemical characteristics of waters in the major aquifers and the areal patterns of any ground-water contamination;

Provide guidelines for the establishment of networks to monitor ground-water levels and ground-water quality; and

Determine the feasibility of constructing a three-dimensional ground-water-flow model for the area.

Because surface-water resources in the county have been fully appropriated for many years, Thurston County now relies almost entirely on ground water for domestic, public supply, agricultural, and industrial uses. Any addi tional development in the county constitutes an additional stress on the ground-water system.

State and county officials share a number of concerns about ground-water conditions in the northern part of Thurston County. These concerns include:

The highly porous nature of the sand and gravel deposits present at land surface throughout much of the county that makes the aquifers in those areas susceptible to contamination;

Potential contamination of the aquifers by the use and spillage of various hazardous substances in a variety of residential, agricultural, and industrial uses;

Elevated concentrations of nitrate in the ground water upgradient from the county's McAllister Springs, which supplies water to most residents of Olympia, the State capital;

The continual increase in demand for ground water and the lack of alternative water sources; and

Purpose and Scope

This report summarizes the findings of the first three objectives of the study described above. The last objec tive, determining the feasibility of modeling, has been completed, and construction of a steady-state flow model was in progress as of the writing of this report. The topics covered in this report include the areal geometry of the aquifers and confining beds, the ground-water flow sys tem, the relation between ground and surface waters, water-quality characteristics of the principal aquifers, and trends in ground-water levels.

The data-collection stage of this study was structured along two main premises: (1) Only those data either already available or readily collectible would be used that is, no test drilling or borehole geophysical logging was envisioned for this study; and (2) because of the size of the study area and the heterogeneity of the subsurface deposits, a regional perspective would be used in charac terizing and describing the individual geohydrologic units and the water movement and quality in each aquifer. Although the general perspective is regional, a greater density of data was collected near McAllister Springs due to its importance as the major water supply in the study area.

Seawater intrusion along northern coastal areas.

The United States Geological Survey (USGS) entered into a cooperative study with the Thurston County Depart ment of Health to characterize the ground-water system in the Quaternary deposits that underlie northern Thurston County, including the designated Ground Water Manage ment Area. The objectives of that study were to:

Describe and quantify the ground-water system to the extent that existing or readily collectable data allow;

Description of the Study Area

The study area consists of 439 square miles in the northern part of Thurston County (fig. 1), and includes the designated Ground Water Management Area (GWMA) of the county, which covers 232 square miles. The study area is bounded on the east by the Nisqually River (pi. 1), on the north by the various marine inlets of Puget Sound, and on the west by the Black Hills. The southern and part of the eastern boundary are based partly on township and section lines, as well as geologic contacts.

The topographic surface of the study area is largely the result of erosion and deposition during and since the Vashon Stade of the Fraser Glaciation (during the last 15,000 years). For the most part, the land surface is a low-lying, drift-covered glacial plain that ranges in alti tude from 200 to 400 feet above sea level. Relief on the plain is generally low, but the plain terminates in steep bluffs at the shores of Puget Sound. Parts of the relatively flat plain where trees are absent are referred to locally as "prairies." The plain has been dissected by rivers and streams of small to medium size, but local closed depres sions, some of which are occupied by lakes, ponds, and wetlands, are common. In particular, an area of terminal moraine in the vicinity of Lake St. Clair has numerous ket tles of glacial origin (see Flint, 1971, p. 212-213). There are four major peninsulas at the northern edge of Thurston County that extend northward into Puget Sound. In this report, the four peninsulas will be referred to informally, from west to east, as the Griffin, Cooper Point, Boston Harbor, and Johnson Point peninsulas (pi. 1). The physi ography of Thurston County is further described by Wallace and Molenaar (1961, pi. 1).

The climate of Thurston County, and of the study area, is of the mid-latitude, West Coast marine type, char acterized by warm, dry summers and cool, wet winters. Moist air masses reaching the county originate over the Pacific Ocean, and this maritime air has a moderating influence in both winter and summer (Phillips, 1960). Pre vailing winds are from the south or southwest in fall and winter, gradually shifting to the northwest or north in late spring and summer.

The long-term mean annual air temperature at Olympia is 49.6 °F; July is the warmest month and January the coldest (63.0 °F and 37.2 °F, respectively.) Afternoon temperatures are usually in the 70's in summer and from the upper 30's to lower 40's in winter.

During the wet (winter) season, rainfall is usually of light to moderate intensity and continuous over an exten sive period of time. The long-term mean annual precipita tion is about 51 inches at Olympia (National Oceanic and Atmospheric Administration, 1982), but ranges from about 35 inches in the northeastern part of the county to about 65 inches in the northwestern and southeastern parts of the county (fig. 2). The areas of greater precipitation are largely a result of the lifting and cooling of moist mar itime air by relatively high landforms. The 51 inches of precipitation at Olympia is also the approximate mean value of the precipitation that falls throughout the GWMA.

Seventy-nine percent of the precipitation at Olympia falls in the 6-month period October to March. July has the least mean monthly precipitation and December the great est (0.76 inch and 8.70 inches, respectively.) Total rain fall for the three driest months (June, July, and August) is less than 7 percent of the annual total. Most of the winter precipitation falls as rain at altitudes below 1,500 feet, as rain or snow between 1,500 and 2,500 feet, and as snow above 2,500 feet (Phillips, 1960).

The study area is drained by three prominent rivers the Nisqually, Deschutes, and Black Rivers and by numerous smaller streams such as McAllister, Woodland, Woodard, Percival, Salmon, Spurgeon, and Eaton Creeks (pi. 1). None of the drainages of the three principal rivers is completely enclosed within the study area. The princi pal lakes in the study area are Black, Capitol, Hewitt, Hicks, Long, Offutt, Pattison, St. Clair, Scott, Summit, and Ward; they are described by Bortleson and others (1976).

The type of native vegetation is largely dependent on the moisture-holding capacity of the soil. Poorly drained, fine-grained soils support mostly coniferous firs and cedars and deciduous alder and madrona. Beneath these trees is a lush understory of huckleberry, Oregon grape, salal, and blackberry. On the well-drained prairies, under lain by coarse-grained outwash, the vegetation consists chiefly of wild grasses, bracken fern, Scotch broom, and isolated patches of firs and oaks.

The 1988 population of the study area, which includes Olympia, Lacey, and Tumwater, is estimated to be about 136,300 (Thurston Regional Planning Council, 1989), or 91 percent of the county population. On the basis of the distribution of residences in Thurston County, approxi mately 41 percent of the study-area population resides within the boundaries of those three cities. The population of the GWMA was about 123,800 in 1988. Many people who work in or near the urban core of northern Thurston County live outside the study area in a rural environment or in the smaller cities and towns of Yelm, Rainier, Tenino, and Littlerock (see pi. 1). The population of Thurston County, and most likely the study area and GWMA as well, has more than tripled from 1950 to 1988. As in most metropolitan areas, the suburban and rural areas have grown at a faster rate than the more densely populated cit ies (fig. 3); this trend is expected to continue in the near future.

Site-Numbering System

Because Olympia is the capital city of Washington, the economy of Thurston County and the study area is dominated by State government. In 1987, State govern ment accounted for 30 percent of the employment in the study area; by contrast, manufacturing and agriculture accounted for only 7 and 3 percent, respectively. Throughout Thurston County there are only 8 manufactur ers with more than 100 employees, and only one, a brew ery, with more than 400. Agricultural pursuits in the study area include dairy cattle, tree farms, wholesale nurseries, egg and poultry production, strawberries, mushrooms, and oyster harvesting.

In Washington, wells are assigned numbers that iden tify their location within a township, range, section, and 40-acre tract. For example, well number 18N/01W-12J02 (fig. 4) indicates that the well is in township 18 North (N) and range 1 West (W) of the Willamette base line and meridian. The numbers immediately following the hyphen indicate the section (12) within the township; the letter following the section gives the 40-acre tract of the section, as shown on figure 4. The two-digit sequence number (02) following the letter indicates that the well was the second well in that 40-acre tract entered into the USGS data base. For springs, the sequence number is fol lowed by the letter "S". If a well has been deepened or significantly reconstructed, the sequence number is fol lowed by the letter "D" and a number indicating the sequence of deepenings or reconstructions.

GEOLOGIC FRAMEWORK

Many studies have contributed to our current under standing of the geologic framework of the study area. Detailed descriptions of geologic conditions in Thurston County, its environs, and the Puget lowland in general are provided by Bretz (1910, 1911, 1913), Mundorff and others (1955), Snavely and others (1958), Crandell and others (1958 and 1965), Crandell (1965), Noble and Wallace (1966), Hall and Othberg (1974), Thorson (1980),

Easterbrook and others (1981), Lea (1984), and Gower and others (1985). The brief summary that follows is taken largely from the work of Noble and Wallace (1966).

Continental glaciers advanced into Thurston County at least twice during the Pleistocene Epoch. The most recent glaciation of the study area, referred to as the Vashon Stade of the Fraser Glaciation, began about 15,000 years ago when the climate cooled and a great con tinental ice mass formed in British Columbia, Canada. The glacier slowly moved southward, blanketing the entire Puget Sound basin. The southern part of Thurston County, near Tenino (pi. 1), is generally regarded as the southern most extent of continental glaciation in western Washing ton. Previous investigators have postulated that the southern advance of the glacier(s) was halted at this approximate location because of the configuration of bed rock at land surface.

As the Vashon glacier advanced southward, rivers and streams that once flowed northward, including the Nisqually and Deschutes Rivers, were blocked, and a large lake formed in front of the ice. This lake received runoff from both the blocked rivers and from the advancing gla cier itself. Eventually, the rising lake breached its tempo rary basin and established drainage channels westward and southwestward into the valley of the Chehalis River, which drains directly to the Pacific Ocean. The Vashon Glacier remained at its maximum southern extent for a relatively short time. As the climate warmed, about 13,500 years ago, the glacier began retreating northward and drainage to the north through the Puget lowland to the Strait of Juan de Fuca eventually was reestablished. This most recent glaciation, however, left behind a characteris tic sequence of glacial drift. Glacial deposits are of two general types, outwash (moderately to well-sorted sands and gravels) and till (unsorted sand, gravel, and boulders in silt and clay matrix).

As a result of the events described above, the study area of northern Thurston County is underlain by unconsolidated deposits of the Pleistocene Epoch that are of both glacial and nonglacial origin (table 1). Beneath these unconsolidated deposits, which are as much as 1,800 feet thick, are consolidated rocks of Eocene to Miocene age, which are referred to in this report as bedrock.

The youngest geologic unit in the study area consists of alluvial and deltaic sand and gravel of Holocene age. The alluvium is generally found along the valley bottoms of the principal streams and is of limited areal extent.

The Vashon recessional outwash is the next youngest unit and consists of poorly to moderately well-sorted sand and gravel laid down by streams emanating from the melt ing and receding glacier. A large part of the study area is mantled with this unit. Included in this unit is the glacial drift that was deposited at the terminus of the stationary or slowly retreating ice mass and labeled Vashon end moraine by Noble and Wallace (1966). Areas underlain by end moraine are characterized by hummocky terrain in which closed depressions (kettles) are common. Exten sive areas of such kettled terrain are present north and southeast of Lake St. Clair and southwest of Black Lake (pi. Ib). A close examination of the bathymetric map of Lake St. Clair (Bortleson and others, 1976, p. 181-184) indicates that the lake basin most likely is formed of coa lescing kettles within the end moraine. Numerous other lakes in Thurston County, such as Hewitt and Ward Lakes, are situated in closed depressions that are also kettles. Some of the smaller kettles are situated above the water table and therefore contain no water.

In most places beneath the Vashon recessional outwash is Vashon glacial till, commonly referred to as "hard- pan" or "boulder clay," which consists of unsorted deposits of sand, gravel, and boulders encased in a matrix of silt and clay. The till is compact where it was laid down beneath the heavy mass of glacial ice and relatively non- compact where it formed during glacial melting. Till is exposed extensively at land surface in the northern, east ern, and south-central parts of the study area (pi. Ib).

Some materials that are found at or near the surface in the study area and resemble Vashon till may actually be part of an older till unit, the "penultimate till" of Lea (1984). Lea mapped this older till near Tenino. In the southeastern part of the study area, there are indications in some drillers' logs of a sequence of two (or more?) tills alternating with outwash. These till sequences may repre sent multiple Vashon tills or the deeper tills may represent older tills associated with glacial sequences prior to the Vashon.

As the Vashon Glacier advanced southward into Thurston County, large quantities of stratified sand and gravel were deposited by meltwaters at the front and sides of the ice mass. This Vashon advance outwash typically consists of fine- to coarse-grained glacially derived sand and subordinate gravel grading upward to poorly to mod erately well-sorted, well-rounded gravel in a sandy matrix, interbedded with lenses of sand. Surface exposures of Vashon advance outwash are not common, but the unit is found at depth over most of the study area.

Beneath the advance outwash is a generally fine-grained assemblage of clay and silt with minor amounts of sand, gravel, peat, and wood. In many loca tions, this deposit is most likely the Kitsap Formation described by previous investigators. Surface exposures of this unit are found in several places along the shoreline. The unit typically occurs as high vertical bluffs above pen insular beaches. The Kitsap Formation is thought to have been deposited in shallow lakes and swamps and is proba bly nonglacial in origin.

Situated directly below the Kitsap Formation is a deposit of pre-Vashon glacial origin (table 1). This unit consists of coarse stratified sand and gravel that is com monly stained with iron oxides to a yellowish brown or reddish brown color. Noble and Wallace (1966) referred to this deposit as the Salmon Springs(?) Drift. However, Easterbrook and others (1981) and Lea (1984) have sug gested that the Salmon Springs(?) Drift at its type locality is much older than previously assumed, and further, that it should not be correlated to more distant locations. Noble (1990) also recommended that use of the term should be discontinued in Thurston County. The unit is at the sur face in several shoreline locations and in the southern part of the study area.

GROUND-WATER HYDROLOGY

The bulk of the data used in this study to describe and quantify the ground-water system in the Quaternary deposits came from information associated with approxi mately 1,320 wells and springs that were inventoried in the field during the early stages of the study (pi. la). This number is estimated to represent only about 20 percent of the total number of wells and springs in the study area. Data pertaining to the inventoried sites are presented in table Al of Appendix A. The inventory process included locating the site in the field; determining its latitude, longi tude, and approximate land-surface altitude; measuring the water level in the well where practical; compiling, analyz ing, and interpreting the information incorporated on the driller's report of the well construction, lithology, and test ing; and then entering the information into a computerized data base. Four of the wells in table Al were not invento ried during the field stage of the project, but were added during the report revision period. Three of these four wells are test wells or monitoring wells drilled near McAllister Springs in 1992. The fourth well is the Hawks Prairie test well (Robinson & Noble, 1984) and was added to the data base to supply needed geohydrologic informa tion to assist in interpreting the complex geohydrology in this area.

Beneath the Salmon Springs(?) Drift is a sequence of fine- and coarse-grained sediments extending to bedrock. These sediments are the "unconsolidated and undifferentiated deposits" of Quaternary-Tertiary age in table 1. Little is known about the lithologic character of these unconsoli dated deposits, but they are believed to be of both glacial and nonglacial origin and may be similar in nature to the overlying sequence of sediments.

The consolidated rocks that make up the bedrock con sist largely of Tertiary sedimentary claystone, siltstone, sandstone, and some beds of coal (Snavely and others, 1958). Associated with these sedimentary rocks are igne ous bodies of andesite and basalt. In the Black Hills and near Tumwater, the bedrock is basalt. Bedrock is exposed in the southern and western parts of Thurston County, near Turn water, and near the head of Eld Inlet. One of the com ponents of the bedrock is the Mclntosh Formation, a marine sediment of Eocene age which can have a signifi cant effect on water quality (see section on Ground-Water Quality). The bedrock slopes downward to the northeast beneath an increasing thickness of unconsolidated depos its. Beneath the northeastern boundary of the study area, the top of bedrock is probably more than 1,800 feet below sea level (Jones, 1996).

Conceptual Model of the Ground-Water System

A generalized conceptual model of the ground-water system beneath northern Thurston County is shown on fig ure 5. This conceptual model shows the general nature of ground-water flow through the unconsolidated geohydro logic units.

Part of the precipitation falling on the inland glacial- drift plains infiltrates past the plant root zone and recharges the ground-water system. Ground water in recharge areas moves vertically and horizontally to dis charge points such as springs, major stream channels, and Puget Sound. The directions of ground-water movement within the system are shown with arrows on figure 5. Movement is generally horizontal in aquifers and vertical in confining beds. The amount of time required for an individual particle of water to complete its journey through the system is roughly proportional to the length of the arrow. Generally, water particles with a relatively short travel path from recharge point to discharge point may be in the ground-water system for only a few weeks or months; particles with relatively long flow paths may be in the system for years or centuries.

Ground water in the study area occurs in aquifers under two different conditions. If water only partly fills an aquifer, the water table (the upper surface of the saturated zone) is free to rise and fall with changes in recharge and discharge. The position of the water table is represented by water levels in shallow wells. In this situation, the ground water is said to occur under unconfined or "water table" conditions.

If water completely fills an aquifer that is overlain and underlain by a confining bed, such as clay or bedrock, ground water is said to occur under confined or "artesian" conditions. Wells that tap a confined aquifer encounter water that rises in the well to a height corresponding to the potentiometric surface or "head" of the confined ground water at that point. If the head is sufficient to raise the water above land surface, the well will flow and is called a flowing artesian well. Confined ground water has a poten tiometric surface analogous to the water table, but the shape of the potentiometric surface may differ greatly from that of a water table. The potentiometric surface, like the water table, fluctuates in response to changing recharge and discharge conditions.

The series of aquifers and confining beds in the study area (fig. 5) constitutes a system in which water flows ver tically between layers. A stress (for instance, pumping) in an aquifer can produce responses (water-level changes) in other aquifers.

More-detailed descriptions of the recharge, move ment, and discharge of water in the ground-water system of northern Thurston County are given in the later sections of the report.

Geohydrologic Units

The geologic units described previously were differ entiated into aquifers and confining beds using lithologic, water-level, and well-yield data for the approximately 1,320 wells included in the study (Appendix A, table A2). The aquifers and confining beds thus defined are referred to as "geohydrologic" units in this report because they were identified based on a combination of geologic (pri marily grain size and sorting) and hydrologic (hydraulic conductivity and hydraulic continuity) properties. In mak ing the differentiation, it is important to keep in mind the heterogeneity of the sediments involved. A glacial aquifer may be composed predominantly of sand and (or) gravel, but in the small scale it will probably also contain rela tively thin and discontinuous lenses of clay or silt. Con versely, a confining layer, composed predominantly of silt

and (or) clay, may also contain local lenses of coarse sand or gravel. As a consequence, the general occurrence and movement of ground water may be influenced locally by these small-scale variations in lithology.

In order to increase our geohydrologic knowledge of the study area and to permit a more detailed, three-dimen sional characterization of it, 17 preliminary geohydrologic sections were constructed using about 420 drillers' logs. These sections were tied to a modified version of the surficial geology map of Thurston County presented by Noble and Wallace (1966) (pi. Ib). The preliminary sections were combined with the remaining 720 drillers' logs to delineate 7 major geohydrologic units (table 1), 6 of which are in the unconsolidated deposits. Five revised final sec tions, considered typical of the study area, are shown on plate Ic. An examination of those sections indicated a great deal of variation in the thickness of individual units, and that not all seven units are necessarily present at any one location.

Because of its location at or near land surface, and because it is relatively undisturbed, the Vashon Drift has been more carefully studied than other, older drifts. Accordingly, previously accepted and published nomen clature associated with the Vashon Drift was used for three geohydrologic units the Vashon advance outwash (Qva), Vashon till (Qvt), and Vashon recessional outwash (Qvr).

Because of their lithologic similarities, Holocene allu vium and Vashon recessional outwash were combined as a single geohydrologic unit (Qvr). A large part of the study area is mantled by unit Qvr (pi. Ib). This coarse-grained unit can be a productive aquifer, and is important as a water supply locally. Throughout most of the study area, however, few wells withdraw water from Qvr because the unit is thin or it lies above the water table and is unsaturated. This is especially true where the underlying till, which retards downward percolation, is absent (pi. 2b). Most of the wells that tap Qvr are in the south-central part of the study area where ground water occurs under water-table (unconfined) conditions, and they produce moderate yields for domestic purposes. Locally, perched ground-water conditions (local zones of saturation above the regional water table) may exist within the Qvr because of the low vertical permeability of the underlying till. Where present, Qvr is generally between 10 and 50 feet thick, but locally may be as much as 150 feet thick (pi. 2a).

12

The Vashon till, and possibly some older tills, make up geohydrologic unit Qvt. In some shoreline loca tions, "Late Vashon lake deposits" (Washington State Department of Ecology, 1980) were correlated with the Qvt because they tend to act as confining beds and occur at the same stratigraphic position as the Qvt. The Qvt is gen erally a poor source of water and is considered a confining bed. About 25 inventoried wells tap thin layers of rela tively clean sand and (or) gravel that are irregularly dis tributed within the unit. The unit is broadly distributed (pi. 2b) and exists at land surface throughout a large part of the study area. At one time, dozens of shallow dug wells produced water from the upper, less compact part of the unit (Wallace and Molenaar, 1961). As reported by Noble and Wallace (1966), perched ground water is present near the top of the unit, and many of the shallow wells that rely on the till occasionally go dry in late sum mer. Where present, Qvt is generally between 25 and 60 feet thick, but locally may be as much as 180 feet thick (pi. 2b).

The Vashon advance outwash is represented as geohy drologic unit Qva, which is an important aquifer in north ern Thurston County. It is present throughout a large part of the study area, mostly in the subsurface. Qva is used extensively in the Tumwater area, where it yields large quantities of water to municipal and industrial wells. It is not developed extensively in the extreme northern parts of the study area, where it is relatively thin (pi. 2c). Ground water in this aquifer typically is confined by the overlying Qvt and the underlying Qf. Where present, the unit is gen erally between 15 and 35 feet thick, but locally exceeds 145 feet thick (pi. 2c). The top of the Qva generally occurs between 50 and 200 feet above sea level (pi. 3a). In the vicinity of McAllister Springs, the large thickness of coarse-grained sediments was divided somewhat arbi trarily into Qvr, Qva, and Qc. That part identified as Qva was selected to be laterally continuous with Qva identified to the west and south, although its actual geologic identity is unknown.

The Kitsap Formation and other poorly permeable materials occurring beneath the Qva are represented as geohydrologic unit Qf. Included in Qf are the fine-grained deposits underlying the Nisqually River delta area. These deposits are undoubtedly much younger than the Kitsap Formation. The upper surface was mapped as Quaternary alluvium by Noble and Wallace (1966). They were included in Qf because they are of similar lithology and are, at least in part, laterally continuous with the other Qf materials adjacent to Nisqually delta. Also included in Qf, but not correlative with the Kitsap Formation, are some till

units. Where multiple tills were observed, generally the uppermost was assigned to the Qvt and the lower tills to the Qf. Unit Qf confines ground water in the coarse grained glacial deposits both above and below it. The unit is not made up solely of fine-grained materials; about 40 inventoried wells tap local, thin lenses of sand or gravel that yield relatively small quantities of water suitable for domestic use. Where the unit is present (pi. 2d), Qf is effective in retarding the downward percolation of ground water into Qc (described below), and in causing vertical head gradients between the Qva and Qc aquifer units. Where present, Qf is generally between 15 and 75 feet thick, but locally is greater than 150 feet thick (pi. 2d).

The coarse-grained Salmon Springs(?) Drift, penulti mate deposits, and other deposits are represented as geo hydrologic unit Qc. Qc constitutes one of the most widely used aquifers of northern Thurston County. The unit is present throughout most of the study area (pi. 3b). Ground water in this aquifer occurs under confined conditions for the most part. In some locations, such as near McAllister Springs where the overlying confining bed (Qf) is absent, Qc merges with the lithologically similar Qva above it to form a single thick and productive aquifer. Where the entire thickness of Qc has been penetrated, it is observed to be generally about 30 feet thick, with a maximum observed thickness of more than 200 feet. The top of the unit ranges from more than 50 feet below sea level to more than 600 feet above sea level and is commonly between 50 feet and 150 feet above sea level.

The unconsolidated and undifferentiated sediments beneath Qc are designated as geohydrologic unit TQu. Although there are nearly 200 inventoried wells that tap the heterogeneous unit TQu, the wells tap several different water-bearing layers that are irregularly distributed both laterally and vertically. Ground water in these layers is generally confined. TQu is an important aquifer in the study area. Deeper untapped water-bearing layers may exist within this unit, especially in the northern part of the study area where the unit is relatively thick. The unit has not been more extensively developed because sufficient quantities of ground water can usually be found at shal lower depths. Few wells penetrate the entire assemblage of unit TQu in the northernmost part of the study area, and the maximum thickness of the unit in that area, therefore, is uncertain. The best estimate of maximum thickness in the study area (Jones, 1996) is somewhat in excess of 1,800 feet. Layering in TQu may be similar to that of the Vashon Drift, described previously.

13

The consolidated rocks of Tertiary age that constitute the bedrock are represented by geohydrologic unit Tb. This unit contains small quantities of water in fractures and joints that are more numerous near the top. In general, however, Tb is an unreliable source of ground water and many wells drilled into this unit in Thurston County have been subsequently abandoned because of insufficient yield or poor-quality water. Most of the more than 70 invento ried wells that tap bedrock are located in the southern and western parts of the study area and supply water for domestic use. Where the bedrock is exposed at land sur face (pi. Ib), the ground water is likely to occur under water-table conditions; where the bedrock is covered by a significant thickness of unconsolidated deposits, espe cially clays and silts, the ground water is likely to be con fined.

The relative importance of each of the geohydrologic units as a source of ground water can be determined from (1) a graph of the number of study wells finished in each of them (fig. 6), and (2) a comparison of the quantities of water withdrawn from each unit for various beneficial uses (see section on Discharge). The resulting information indicates that units Qvr, Qva, Qc, and TQu are the princi pal sources (aquifers) of water for existing wells and springs in northern Thurston County, but that usable quan tities of ground water can also be obtained from units Qvt, Qf, and Tb. Even though units Qvt and Qf generally func tion as confining beds, numerous wells produce water from thin, local lenses of sand or gravel in these otherwise poorly permeable deposits. In areas where two or more aquifers are combined, that is, where the intervening con fining bed is absent, the combined units function as a sin gle aquifer.

At the local scale, an important geohydrologic unit has been identified, the McAllister gravel aquifer. The fol lowing description is from John Noble (Robinson & Noble, Inc., personal commun., 1998) and Pacific Ground- water Group (1997). The visible discharge point of this aquifer is McAllister Springs, which is the largest public water-supply source in the study area. The McAllister gravel aquifer is composed of pebbles to boulders that appear to be a channel fill deposited by the ancestral Nisqually River. The unit extends below McAllister Springs to at least 250 feet below sea level, is very narrow, and probably continues to the north of McAllister Springs beneath the Nisqually River delta. The southerly extent of the unit is unknown, but there are indications that the unit might extend to the existing Nisqually River just north of Yelm.

Laterally, the McAllister gravel aquifer is in contact with units Qvr, Qva, and Qc. Because of this lateral con nection, and the regional perspective of this study, the McAllister gravel aquifer was divided into layers and incorporated in units Qvr, Qva, and Qc.

Hydraulic Conductivity

An estimate of the magnitude and distribution of hori zontal hydraulic conductivity of each aquifer is helpful in understanding the discharge and availability of the ground water within the aquifer. Determinations of the horizontal hydraulic conductivity (a measure of permeability) for each aquifer were computed from transmissivity values that were calculated from specific-capacity data. Trans missivity is equal to an aquifer's hydraulic conductivity times its thickness. Specific capacity is a measure of a well's productivity and is equal to the pumping rate divided by the drawdown in a well. Horizontal hydraulic conductivity is a measure of a hydrologic unit's ability to transmit water horizontally. For unconsolidated materials, hydraulic conductivity depends on the size, shape, and arrangement of the particles. Horizontal hydraulic con ductivity is the volume of water that will move in unit time under a unit gradient through a unit area (measured at right angles to the direction of flow). It is in units of cubic feet per square foot per day, commonly simplified to feet per day. Hydraulic conductivities were calculated for all wells that had specific-capacity information (discharge rate and drawdown) and that are open to a single geohydrologic unit; 913 of the 1,340 wells met these criteria.

Either of two methods was used to estimate hydraulic conductivity, depending on how the well was finished. For wells that had a screened or perforated interval, values of horizontal hydraulic conductivity were estimated from specific-capacity data by using the Theis method for water-table units and the Brown method for artesian units (both in Bentall, 1963). The specific-capacity data were obtained from well records and generally represent short-term (about 4-hour) pumping or bailer tests con ducted by well drillers at the time the wells were originally completed. The Theis and Brown methods actually calcu late a transmissivity value. These transmissivity values were divided by the length of the open interval(s) in each well to estimate hydraulic conductivity. Using the open interval of the well as being equal to the total aquifer thickness assumes that all the water flow into the well dur ing the test was horizontal flow, although some of the flow presumably came from above or below the open interval.

This may result in an overestimation of hydraulic conduc tivity. The amount of error caused by this assumption is probably small because layering within the geohydrologic units tends to make horizontal flow much easier than verti cal flow. For wells having only an open end, and thus no vertical dimension to the open interval, hydraulic conduc tivity was estimated using Bear's (1979) equation for hemispherical flow to an open-ended well just penetrating a geohydrologic unit. When modified for spherical flow to an open-ended well within a unit, the equation becomes:

(1)

where

k, is horizontal hydraulic conductivity, in feet per day,

Q is discharge, or pumping rate, of the well, in cubic feet per day,

s is drawdown in the well, in feet, and

r is radius of the well, in feet

Equation 1 is based on the assumption that horizontal and vertical hydraulic conductivities are equal, which is not likely for the deposits in the study area. Violating this assumption probably results in an underestimation of k, by an unknown factor.

The data were statistically analyzed for all geohydro logic units so that medians, ranges, and differences between units could be determined. Hydraulic conductiv ity data for those aquifers with sufficient data points (Qva and Qc) were examined to determine if there are distinct areal patterns of lower or higher values. Individual values of hydraulic conductivity can be found in the table of well data (Appendix A, table Al). A summary of hydraulic- conductivity data by aquifer is given in table 2. Of signifi cance in table 2 is the fact that the median values for the three upper aquifers (Qvr, Qva, and Qc) are remarkably similar (from 150 to 160 feet per day). The available data for the two uppermost confining units (Qvt and Qf) also indicate similar median values (14 and 17 feet per day, respectively) and are approximately an order of magnitude less than the aquifers. However, the values for Qvt and Qf represent only the coarse-grained parts of these units. True median values for these units, including the fine-grained portions, are probably much less than indi cated by the available data. TQu represents a series of aquifers and confining beds and has a median value (74 feet per day) that is between the medians of the other aquifers and confining beds.

Identification of areal patterns of hydraulic conductiv ity is extremely difficult given the available data. The depositional nature of the units probably results in a sys tem of "channels" of relatively coarse materials and there fore a three-dimensional distribution of hydraulic conductivity that is not readily discernible in a two-dimen sional plot of the data. No areal patterns for hydraulic conductivity were observed for Qva and, although no clear areal patterns were evident for Qc, there are two areas where high values cluster and one area of low values. The areas of high hydraulic conductivity (high frequency of values equal to or greater than 1,200 ft/d) in Qc are around McAllister Springs (from Lake St. Clair to Puget Sound and from Long Lake to the Nisqually River) and near Littlerock (a 6-mile stretch along the Black River from just northeast of Littlerock to the southwest). Between these two areas of high values is a northeast-southwest trending zone of low values (high frequency of values equal to or less than 32 ft/d). Because no definitive-areal trends in hydraulic conductivity were observed in any of the water-bearing geohydrologic units, no maps of the data are presented in this report.

No data are available to estimate the vertical hydrau lic conductivity of aquifers or of confining layers between aquifers. Estimates made in other areas within Puget Sound with similar deposits indicate that vertical hydrau lic conductivity probably ranges from 0.0001 to 0.01 ft/d for the confining layers (Vaccaro and others, 1998).

Recharge

The bulk of the recharge to the ground-water system of the study area is derived from the infiltration of precipi tation. Secondary sources of recharge include seepage from septic systems, leakage from water and sewer lines, and deep percolation of irrigation water. Recharge from precipitation occurs essentially everywhere, with the pos sible exceptions of (1) areas of ground-water discharge and (2) those areas covered by impermeable, man-made materials such as asphalt and concrete. However, imper meable materials at land surface may only delay and redis tribute the recharge process; precipitation that runs off impermeable surfaces may seep into the ground as soon as it encounters natural permeable materials. Throughout a large part of the greater Olympia area, precipitation that might otherwise recharge the aquifer(s) is diverted through storm drains to Budd Inlet, resulting in less recharge beneath Olympia than in areas without storm drains. Sim ilarly, there is little or no recharge from septic tank filter- field leachate in the Olympia area because domestic sew age there is diverted to central sewage-treatment facilities and then to Budd Inlet. Most of the precipitation recharge in the study area occurs in the 6-month period October- March, when precipitation greatly exceeds evapotranspiration. The following calculations of recharge were made for the GWMA only, as this is the area for which a water budget is to be calculated.

The amount of precipitation recharge to the GWMA was first estimated by applying the precipitation-recharge relations derived for till and outwash units in nearby King County (Woodward and others, 1995) to similar units in the study area. These relations, graphically shown on fig ure 7, are based on the application to King County of a deep percolation (recharge) model developed by Bauer and Vaccaro (1987). Figure 7 also shows estimated pre cipitation-recharge relations for the kettled outwash and bedrock units. The kettled outwash was separated from the rest of the outwash unit(s) on the assumption that, hav ing closed drainage, it would have somewhat greater recharge than outwash with open drainage to the sea. This incremental difference was estimated to be 10 percent. The recharge value for bedrock was estimated to be half that for till for an equivalent amount of precipitation. In addition, Qf was considered to have the same recharge characteristics as Qvt because of their somewhat similar hydrologic properties.

In order to determine the distribution of recharge in the GWMA, a map of recharge rates was prepared based on the long-term precipitation map (fig. 2), a map of the surficial distribution of the geohydrologic units (pi. Ib),

and the precipitation-recharge relations shown on figure 7. The resulting recharge-rate maps were then overlaid on a map of surficial distribution of the geohydrologic units. The resulting recharge map (pi. 3c) indicates that recharge rates are higher in the west-central part of the GWMA, where relatively more precipitation falls on outwash and kettled outwash. Recharge rates are lower on the flood plains of McAllister Creek and the Nisqually River to the east, and in the basalt hills of the extreme western part of the GWMA. An integration of the resulting polygons on plate 3c indicates that the ground-water system as a whole beneath the northern Thurston County GWMA receives an average of about 28 inches of recharge in a typical year.

To corroborate the first estimate of recharge, a second estimate was made using the results of the application of a rainfall-runoff model (U.S. Environmental Protection Agency, 1984) to three drainage basins within the study area. The results of pilot studies in Percival, Woodland, and Woodard Creeks (pi. 1) by Berris (1995) were extrap olated to the entire GWMA in the form of regression equa tions. The independent variables for the regression analyses were precipitation, air temperature, evapotranspiration, soil type, land cover, land slope, and available water capacity of the soil. The model was run using climatological data for 28 consecutive years (1961 through 1988). Factors not considered because they were outside the scope of this study include such recharge sources as septic-tank leachate, dry-well infiltration, excessive irriga tion, and influent streams and lakes. The results of this second recharge-estimation method indicated that the ground-water system beneath the northern Thurston County GWMA receives an average of about 22 inches of recharge in a typical year.

The estimates derived using both methods were con sidered reasonable, so the average of the two values, 25 inches per year, was used. Assuming that the GWMA covers 232 square miles, this quantity of recharge repre sents an annual volume of about 310,000 acre-feet.

Movement

The ground-water flow system is depicted in part by maps showing the potentiometric surface for the two prin cipal aquifers (pi. 4a and 4b). The maps were constructed by using water levels measured in nearly 800 wells at the time of inventory, supplemented by water levels as reported by drillers for about 250 individual wells. The majority of water levels were measured between May and October 1988. The number and distribution of water lev els in two of the principal aquifers were adequate (about 380 for Qva and about 410 for Qc) to allow the representa-

17

tion of the respective potentiometric surfaces on contour maps. The number of water-level measurements in other, less-widely-used units was more limited, and therefore contour maps were not made for these units. Vertical flow directions were estimated by comparing water levels (heads) in closely spaced wells finished in different aqui fers, and by comparing the maps of the potentiometric sur faces for the two principal aquifers.

Horizontal flow directions of ground water within aquifers Qva and Qc are shown by arrows on plate 4. Flow is from areas of higher head to areas of lower head and, in general, is perpendicular to the contours of equal head. Also included on the plate are the ground-water drainage areas of McAllister Springs for the same units. Water-level data are sparse for Qva east and southeast of McAllister Springs. The boundary of the drainage area is estimated in this region based on topography.

Ground water in Qva generally moves toward marine water bodies and to major surface drainage channels; local mounds on the potentiometric surface occur beneath each of the major peninsulas (pi. 4a). In the vicinity of Lake St. Clair, ground water moves northward toward McAllister Springs. Contours along the lower reach of the Deschutes River indicate that ground-water flow is generally toward the river and that, as a result, river discharge probably increases in that area.

The configuration of the potentiometric surface for Qc (pi. 4b) is similar to that for Qva. Ground-water mounds are present on all four major peninsulas. Flow directions near Lake St. Clair and McAllister Springs are similar to those in Qva. As in the Qva, it appears that the lower reach of the Deschutes River is an area of increased dis charge from the contribution of ground water.

Beneath the upland areas, water levels in Qva are gen erally higher than in Qc (pi. 4c), indicating that water flows vertically downward, passing through Qf where it is present. The differences in head between Qva and Qc are also shown on plate 4. The areas of greater head differen tial coincide largely with ground-water mounds within Qva and with areas where the intervening fine-grained unit Qf is thickest. These areas of greater water-level differen tial should not be interpreted as areas of greater downward flow nor as areas of greater aquifer vulnerability from sur face contamination.

Discharge

Ground water in northern Thurston County discharges as seepage to lakes, streams, springs, and coastal bluffs; as transpiration by plants; as underflow (submarine seepage)

to marine waters; and as withdrawals from wells. Only the amount of water withdrawn from wells and major springs was quantified as part of this study.

As mentioned previously, ground water discharges to some reaches of the principal rivers and streams of the study area, in particular the Nisqually and Deschutes Rivers, augmenting streamflow and producing what is usually referred to as a "gaining reach." Ground-water dis charge sustains the late-summer flow of numerous streams in the study area. A seepage study completed in August 1988 confirmed the assumption that the lower reach of the Deschutes River is a gaining reach. According to Berris (1995), the lower reaches of Percival, Woodland, and Woodard Creeks also are generally gaining reaches. The discharge of Thompson Creek, northwest of Yelm, is greatly enhanced by spring discharge just upstream of the point where it joins the Nisqually River. The discharge of McAllister Creek, which originates at McAllister Springs, is increased by numerous other springs that issue from the base of the bluff just west of the stream.

The principal springs in Thurston County are listed in table 3 and are shown on plate 1 a. The total discharge of these springs is estimated as 45 ft3/s (33,000 acre-ft/yr). There are, in addition, probably hundreds of smaller springs scattered throughout the study area. The total spring discharge in the study area is unknown. McAllister Springs (18N/01E-19Q01S) is by far the largest in the study area in terms of both discharge and surface area. Over the period 1979-88, the mean annual discharge of McAllister Springs ranged from 21.2 to 25.6 ft3/s (Andrew W Hoiland, City of Olympia, written commun., 1990) and averaged 23.6 ft3/s. During the period of this study, the discharge of the spring was below the long-term average (fig. 8) from July 1988 through December 1989, and above the long-term average from January through July 1990.

Ground-water withdrawals from wells was approxi mately 21,000 acre-ft in 1988 (see table 4). Subtracting the 54,000 acre-feet of water discharged to springs or withdrawn by wells from the (gross) recharge value of 310,000 acre-feet calculated previously, leaves a net uni dentified discharge of 256,000 acre-feet per year. This represents the amount of water that eventually is tran spired back to the atmosphere by plants, recharges deeper aquifers, or discharges naturally to seeps, lakes, streams, rivers, Puget Sound, or unidentified springs.

Water-Level Fluctuations and Trends

The configuration of the water table or potentiometric surface is determined by (1) the overall geometry of the ground-water system, (2) the hydraulic properties of the aquifer, and (3) the areal and temporal distribution of recharge and discharge. Where recharge exceeds dis charge, the quantity of water stored will increase and water levels will rise; where discharge exceeds recharge, the quantity of water stored will decrease and water levels will fall.

Previous studies in western Washington have shown that, in years of typical precipitation, ground-water levels in shallow wells generally rise during the wet season of

October through March and fall during the dry season of April through September. Water levels in deep wells gen erally respond more slowly, and usually with less magni tude, than water levels in shallow wells. Near the coast, water-level fluctuations also occur in response to tidal changes; these fluctuations are superimposed on the sea sonal and long-term changes that are related to changing recharge-discharge relations.

A monthly water-level-measurement network within the GWMA was started in November 1988 and wells were added gradually through June 1990 (37 wells total; [table A3, Appendix A]). Most of these wells were mea sured for at least a full year (May 1989 through May 1990). Water levels were generally at their seasonal high-

20

est in February-May and lowest in October-December. Hydrographs of water levels in selected observation wells (fig. 9) indicate that the highs and lows coincided in shal low and deep wells, and that the magnitude of fluctuation was controlled by more than well depth alone.

During the period May 1989 through May 1990 (when the network was most complete), most wells expe rienced a net water-level rise, with a median rise of nearly 1 foot. At the start of this period, the study area had been experiencing a relatively dry period. Annual water-level fluctuations in the network ranged from 2.25 to 17.08 feet, with a median of 5.36 feet. The largest fluctuations took place in bedrock wells.

The detection of long-term trends in ground-water levels requires the plotting and analysis of several years of water-level data. With the exception of a single well, those data are generally lacking in northern Thurston County. Water levels in well 18N/02W-07R01, completed

in unit Qva, were monitored from 1971-80 and during this study. The hydrograph of the data from that well (fig. 10) shows that water levels declined from 1972 to early 1978, possibly because of pumping or, more likely, year-to-year differences in precipitation. Rainfall in 1972, 1974, and 1975 was above the long-term average, whereas in 1973 and 1976-80 it was below average. Climatological data, therefore, indicate that the general decline in water levels observed in well 18N/02W-07R01 from 1972 through 1977 (fig. 10) was probably due chiefly to precipitation patterns. However, the fluctuations might reflect long- term drawdown due to nearby pumping or changes in recharge that may have accompanied changes in pumping. As development has increased, some areas have become sewered, resulting in decreased recharge (compared to septic systems). The increase in the amount of impervious surface with development may have also decreased recharge.

WATER USE

Water-use data generated for this report were for cal endar year 1988 and were derived from such diverse sources as the Washington State Department of Ecology (Ecology), Washington State Department of Health (WDOH), USGS, and reports from utilities and other agencies. Most of the data, however, were obtained by telephone canvassing of the major water users in the study area.

At the time of the water-use canvass, public water systems in Washington were divided into four classes (Washington Administrative Code 248-54).

Class 1 systems had 100 or more services (a physical connection designed to serve a single family) or served a transitory population of 1,000 or more people on any one day.

Class 2 systems had 10-99 permanent services or served a transitory population of 300-999 people on any one day.

Class 3 systems served a transitory population of 25-299 people on any one day.

Class 4 systems had 2-9 permanent services or served a transitory population of less than 25 people per day

Data for all Class 1 systems and some Class 2 systems were obtained by direct contact, either by telephone or let ter, with each system manager or clerk. Where practical, withdrawals were determined for each well in the system. Withdrawals for most Class 2 systems generally were not metered. For the unmetered Class 2 systems, estimates of withdrawals were made based on the following equation:

Annual withdrawal = (number of connections)X (2.5 persons per connection)

X (130 gallons per person per day)

X (365 days)

For purposes of this study, persons served by Class 3 and 4 systems were considered to be supplied by privately owned wells and their domestic withdrawals were calcu lated accordingly.

Ground-water withdrawals from privately owned wells for domestic use were calculated by determining the population of the study area whose homes are supplied water by Class 1 or 2 public water systems (78,000) and

subtracting that number from the total population of the area (124,000), then by applying a per capita rate of 100 gallons per day to the difference (46,000). The rate of 100 gallons per day is an estimate for rural homeowners, as opposed to 130 gallons per day for urban homeowners (DionandLum, 1977).

Ground-water withdrawals for irrigation were calcu lated by one of two methods: (1) by multiplying the pump ing rate of the irrigation well by the owner's estimate of the duration of pumping; or (2) by applying a uniform irri gation rate of 1.5 acre-feet of water per acre per year (irri gation season) to estimates of irrigated acreage. Informa tion about irrigated acreage was obtained by telephone and personal contact with irrigators identified either in the well-inventory process or by the county Agricultural Extension Agent.

Ground-water withdrawals for commercial, industrial, and institutional purposes are either self-supplied (private wells) or from municipal water systems. Withdrawals were estimated for private wells on the basis of telephone canvassing of water users identified in the well-inventory process and in publications such as the telephone directory and employment statistics of Thurston County (Thurston Regional Planning Council, 1989). An effort was made to contact industrial concerns with known high-water use rates or with at least 100 employees. Because of the large number of small commercial and institutional concerns m the study area, however, the canvass of these two catego ries was most likely incomplete. Withdrawals as part of municipal systems were reported by the system managers.

Water used for aquaculture and livestock supplies is primarily from springs. Rates of use were obtained from personnel managing the aquaculture and livestock facili ties and represent both measured and estimated values.

Ground-water use in the GWMA in 1988 was com piled by water-use category, source (well or spring), and geohydrologic unit (table 4, fig. 11). Total ground-water use in 1988 was approximately 37,000 acre-feet. Approx imately 21,000 acre-feet of water was withdrawn through wells. About 16,000 acre-feet of the water that discharges naturally through springs was put to beneficial use. About 48 percent of the total amount of ground water used was for household supply (public supply and "domestic"). Of the 21,000 acre-feet withdrawn from wells, 40 percent came from Qva, and the largest use was for household supply (58 percent). Of the 16,000 acre-feet of spring water used, almost half issued from McAllister Springs and was used primarily for household supply. The remain der issued from other springs and was used largely for the rearing of fish.

Generalized maps of 1988 ground-water use (from wells and springs) are shown on figure 12 for each of the principal geohydrologic units. For the sake of clarity and simplicity, use has been aggregated for each quarter-town ship (9 square miles) within the GWMA. Figure 12 indi cates that ground-water use was concentrated in the more populous parts of the GWMA. The greatest rates of use occured from the Qvr, Qva and Qc, and were centered around McAllister Springs and the Cities of Turn water, Olympia, and Lacey. Most use of water from Tb occured in the southern and western parts of the study area, where more productive aquifers are generally lacking and this unit is at or close to land surface.

Of the 123,800 people estimated to have resided in the GWMA in 1988, about 78,000 (63 percent) had their household water furnished by Class 1 or Class 2 public- supply systems. The remaining 45,800 people (37 percent) relied on privately owned wells and small public-supply systems (mostly Class 4 systems). Of inter est, however, is the fact that most of an estimated 23,000 people served by the City of Olympia Class 1 system were supplied by McAllister Springs water and not by well water. As shown in table 4, withdrawals of public-supply water by wells totaled 6,800 acre-feet in 1988 and most withdrawals (78 percent) were from Qva and Qc. With drawals for domestic use (privately owned wells and small public-supply systems) totaled 5,300 acre-feet, and most withdrawals (70 percent) were from Qva and Qc.

The single largest withdrawal of ground water through wells for commercial-industrial-institutional pur poses in 1988 was in the Turn water area. In that year, a single manufacturer withdrew an estimated 4,700 acre-feet of water, mostly from Qva and Qc. Numerous smaller industrial concerns withdrew relatively small quantities of ground water. It is unlikely that all industrial water users in the GWMA were contacted; the estimated total com mercial- industrial-institutional supply of 6,900 acre-feet, therefore, probably represents a minimum value.

of irrigation water also are taken from local streams, but this use does not constitute a major effect on the ground- water system.

The principal uses of spring water in northern Thurston County are for public supply and aquaculture-livestock (see table 4). In 1988, these two uses accounted for 5,600 and 7,900 acre-feet of spring water, respectively. The public-supply withdrawal for domestic use was from McAllister Springs and amounted to about 33 percent of its annual discharge. It should be noted that the use of spring water does not constitute withdrawal from the ground-water resource, but use of naturally occurring discharge.

The data needed to document long-term trends in ground-water withdrawal are generally lacking. One can assume, however, that withdrawals have increased over time, at least with respect to domestic water supplies, because of the relatively steady growth in population in the study area (see fig. 3).

WATER BUDGET OF THE GROUND WATER MANAGEMENT AREA

An approximate ground-water budget for a typical year in the 232-square-mile GWMA is expressed in the following equation.

GW. +R = D + A5 in

where

GW. is ground-water inflow to the study area,

R is recharge,

D is discharge, and

AS is change in ground-water storage.

(2)

Irrigation water use in 1988 was relatively minor. An attempt was made to account for water being used to irri gate truck farms, tree farms, turf farms, nurseries, and pas tures. The quantity of water used to sprinkle residential lawns was accounted for in the domestic water category.

In 1988, about 2,100 acre-feet of water was with drawn for irrigation. Because not all irrigators could be contacted, this probably represents a minimum value. Irri gation supplies in 1988 were taken from all geohydrologic units except the Qf and bedrock (table 4). Small amounts

Recharge to the ground-water system in the GWMA occurs primarily as recharge from precipitation and sec ondarily as seepage from septic systems, as leakage from water and sewer lines, and as deep percolation of irrigation water. Discharge from the system occurs as seepage to streams, springs, and coastal bluffs, as evaporation from soils and transpiration by plants, as underflow (submarine seepage to Puget Sound and flow to ground water outside the study area boundary), and as withdrawals from wells.

Only some of the water-budget components can be quantified on the basis of the available data. The precipi tation recharge ( R ) is equal to 310,000 acre-ft/yr (see Recharge section). The known discharge from springs is 33,000 acre-ft/yr (see Discharge section). Pumping fromwells ( D ) totals 21,000 acre-ft/yr (see Water Use sec-

PP8 tion). Secondary recharge ( R ) and evapotranspirationfrom the ground water ( D ) are not known but are assumed to be relatively insignificant to the total budget(assume R = 0 and D = 0 ). Ground-waterv sec et 'inflow ( GW. ) and outflow ( D ) are not known. in ' unOn a long-term basis, a hydrologic system is usually in a state of dynamic equilibrium; that is, inflow to the system is equal to outflow from the system and there is little or no change in the amount of water stored within the system (AS = 0).

Substituting the known values and above assumptions into equation 3 yields the following (all values in thou sands of acre-feet per year).

(Rearranging)

GW. +256 = D +D in sw um (3)

This result indicates that most ground-water flow through the study area discharges to surface-water bodies and as underflow to marine waters.

Not all water that discharges naturally is available for further ground-water development. As pointed out by Bredehoeft and others (1982), any new discharge (with drawals) superimposed on a previously stable system must be balanced by an increase in recharge, a decrease in the original discharge, a loss of storage within the aquifer, or by a combination of these factors. Considering the ground-water system of northern Thurston County in par ticular, the possibility of increased natural recharge on a long-term basis appears remote. In fact, the trend of increased residential development and central storm sew ers may result in decreased recharge. Additional with drawals, therefore, would result in a loss of storage (with an attendant decline in water levels) and a decrease in nat ural discharge. As discussed previously, not all natural discharge in the study area is to the sea; a large but unde termined quantity of ground water discharges to streams and springs. In those places, it is used both directly and indirectly for streamflow maintenance, fish propagation, waste dilution, recreation, and public supply. The magni tude of potential ground-water development, therefore, depends on the hydrologic effects on discharge that can be tolerated. Because it may take many years for a new equi librium to become established, the full effects of addi tional ground-water development will most likely not be immediately apparent.

GROUND-WATER QUALITY

In this section, the methods of collecting and analyz ing ground-water quality data are discussed and the qual ity of the ground water in the study area is described. Chemical concentrations and characteristics are discussed by geographic area and geohydrologic unit. Concentra tions are compared with applicable U.S. Environmental Protection Agency (USEPA) drinking water regulations, and causes of widespread or common water-quality prob lems are identified.

Water-Quality Methods

The sampling and analytical methods used in this study follow guidelines presented in U.S. Geological Survey Techniques of Water-Resources Investigations (Fishman and Friedman, 1985; Friedman and Erdmann, 1982; Greeson and others, 1977; Wershaw and others, 1987; and Wood, 1981) and, where applicable, guidelines for GWMA studies as presented by Carey (1986).

Water samples were collected from 356 wells and 3 springs (pis. 5 and 6) during April, May, and June 1989. All samples were analyzed for concentrations of major ions, silica, nitrate, phosphate, iron, manganese, and fecal-coliform and fecal-streptococci bacteria. In addition, field measurements of temperature, specific conductance, pH, and dissolved-oxygen concentration were made at all sites. A subset of 47 samples, taken mostly from wells sit uated in areas of commercial and (or) industrial activity, was analyzed for concentrations of the trace elements arsenic, barium, cadmium, chromium, copper, lead, mer cury, radon, selenium, silver, and zinc, and concentrations of volatile organic compounds. A second subset of 44 samples, chiefly from wells in unsewered areas, was ana lyzed for concentrations of boron, dissolved organic car bon (DOC), and methylene blue active substances (detergents).

Ten of the 365 wells sampled for complete analyses had also been sampled for chloride concentrations in 1978 as part of a regional assessment of seawater intrusion in western Washington (Dion and Sumioka, 1984). An addi tional 102 wells from the 1978 study, all located within a mile of the coast, were resampled for only chloride con centration, providing a total of 112 wells for comparison between 1978 and 1989.

In November 1988, 26 wells and 2 springs between McAllister Springs and Lake St. Clair were sampled to provide background data on water quality for a part of the study area where there was much concern about potential water-quality problems. The samples were analyzed for the same constituents as the 359 samples collected in spring 1989, and were also used to help determine if water chemistry varies with time. Both springs and all but 3 of the 26 wells were resampled in spring 1989.

All the wells sampled in this study had been invento ried and field-located prior to sampling. Most of the wells selected for sampling are used for domestic or, to a lesser extent, municipal purposes; a few are used for agricultural or industrial purposes. The sampled wells were selected to provide broad geographic coverage and a representation of all geohydrologic units. The number of wells selected for sampling within each of the geohydrologic units was approximately proportional to the total number of wells inventoried in each unit. Wells open to more than one geohydrologic unit were not selected. Areas of known ground-water quality problems, such as elevated nitrate concentrations or the presence of pesticides, were consid ered in the well-selection process. Although an effort was made to sample wells that might be representative of widespread water-quality problems, because of the

regional nature of this study no attempt was made to sam ple wells affected by known small-scale or point-source problems. Wells from which samples were analyzed for concentrations of trace elements, volatile organic com pounds, and septage-related compounds were selected largely on the basis of the predominant land use in the gen eral vicinity of the wells. If a selected well could not be sampled for any reason, a substitute well with similar characteristics was selected using the same criteria.

Water samples were usually collected from a hose bib in the well's distribution system as close to the wellhead as possible. All samples were collected prior to any water treatment, such as chlorination, fluoridation, or softening. Where feasible, samples were collected upstream of any holding tank. Water was directed from the hose bib through nylon tubing to a flow-directing stainless-steel manifold mounted in a mobile water-quality laboratory (fig. 13). At a flow chamber, pH, temperature, and dis solved-oxygen concentration were monitored continu ously. Specific conductance was also measured every 5 minutes. When these readings were constant for 10 min utes, indicating that the water monitored was being drawn from the aquifer, raw and filtered samples were collected from the appropriate manifold outlet. Raw samples to be analyzed for concentrations of organic compounds and bacteria were collected last, directly from the hose bib. All sampling equipment was rinsed and cleaned as appro-, priate before subsequent samples were collected.

After collection, samples were treated and preserved according to standard USGS procedures (Feltz and others, 1985). Samples requiring laboratory analysis were sent to the USGS National Water Quality Laboratory (NWQL) in Arvada, Colo. Dissolved concentrations were determined for all inorganic constituents, and total concentrations were determined for all organic compounds except dis solved organic carbon. Analytical procedures used at the NWQL are described by Fishman and Friedman (1985), Thatcher and others (1977), and Wershaw and others (1987).

Determinations of pH, specific conductance, dis solved-oxygen concentration, and temperature were made onsite using methods outlined by Wood (1981). Dis solved-oxygen concentrations were determined using a meter, and concentrations of 1.0 mg/L (milligrams per liter) or less were verified by collecting samples to be ana lyzed at the end of the field day using the Winkler titration method (American Public Health Association and others, 1985; Wood, 1981). Samples were also analyzed in the field for concentrations of fecal-coliform bacteria and fecal-streptococci bacteria using membrane filtration methods outlined by Greeson and others (1977).

As part of the study's quality-assurance program, accuracy of field measurements of pH and specific con ductance was ensured by daily calibration of meters to known standards. Dissolved-oxygen meters were also cal ibrated daily, using the water-saturated air technique. Field analyses of bacteria concentration were performed in duplicate for 1 in every 20 wells sampled.

Samples for analysis by the NWQL were collected in duplicate on a random basis. One duplicate sample for major inorganic analysis was collected for every 20 wells sampled, and one duplicate sample for trace elements and organic analysis was collected for every 15 wells sampled. Blank samples, prepared from deionized water, were ana lyzed at the same frequencies. Duplicates and blanks were processed in the same manner as ordinary ground-water samples and were submitted to the laboratory disguised as normal ground-water samples.

No standards or spiked samples were submitted from the field to the laboratory, but standards for most inorganic constituents were inserted routinely as blind samples into the sample stream at the NWQL. Appropriate standards were spiked into each sample for organic analysis to deter mine the percentage of constituent recovered.

Standard quality-assurance procedures were used at the NWQL (Friedman and Erdman, 1982). The resulting analytical data were reviewed by laboratory personnel, then released to the USGS district office in Tacoma, Wash., by computerized data transfer. The data were then further reviewed by district personnel in the context of the geohydrologic setting. Computer programs and statistical techniques were used to assist in all stages of the reviews. Additional details of laboratory quality-assurance proce dures and data review are discussed in a project qual ity-assurance plan by G. L. Turney (U.S. Geological Survey, written commun., 1988) and in a general plan by Friedman and Erdmann (1982). A detailed review of the quality-assurance data for the project is included in Appendix B of this report. All water-quality data that resulted from this study are presented in Appendix C.

General Chemistry

Most of the data that describe the general chemistry of the ground water are presented statistically in summary tables. Table 5 presents the minimum, median, and maxi mum values of the common constituents determined; table 6 shows median values for each of the common con stituents by geohydrologic unit. Similar summary tables

are presented for other constituents and chemicals as needed for the discussion. All supporting basic data are presented in Appendix C.

For many constituents, some concentrations may be reported as "less than" (<) a given value, where the value given is the detection limit or reporting limit for the ana lytical method. For example, the concentrations of many organic compounds are reported at <0.2 fig/L, (micrograms per liter) where the detection limit is 0.2 (ig/L. The correct interpretation of such concentrations is that the constituent was not detected at or above that particular concentration. The constituent could be present at a lower concentration, such as 0.1 (ig/L, or it may not be present at all, but that is impossible to tell with certainty with the analytical method used.

pH, Dissolved Oxygen, and Specific Conductance

The acidity or basicity of a substance is measured by pH, which in water is measured on a scale from 0 to 14. A pH of 7.0 is considered neutral; smaller values are acidic and larger values are basic. The scale is logarithmic; therefore, a pH of 5.0 indicates that a water is 10 times as acidic as water with a pH of 6.0.

The pH values of the samples collected as part of this study ranged from 6.0 to 9.9 and the median was 7.1 (table 5). The median pH by aquifer increased steadily from 6.7 in Qvr to 7.9 in Tb (table 6). The variation in pH values is natural and is due largely to alterations of the water composition by chemical reactions with minerals in the aquifer material. Some of these reactions and the effects they have on water chemistry are discussed in the section on Water Types.

Dissolved-oxygen concentrations are useful in deter mining the types of chemical reactions that can occur in water. Small dissolved-oxygen concentrations indicate that a chemically reducing reaction can occur, and large concentrations indicate that a chemically oxidizing reac tion can occur. In some instances, though, large dis solved-oxygen concentrations may have been caused by the introduction of air into plumbing systems by pumps, leaking tanks, or pipes. Caution was taken to avoid aera tion of the samples, but sometimes it was unavoidable or undetectable.

Dissolved-oxygen concentrations ranged from 0.0 to 12.6 mg/L, and the overall median concentration was 3.9 mg/L (table 5). Median concentrations varied consid erably by unit, ranging from 6.7 mg/L in Qvr to 0.2 and

32

0.5 mg/L in TQu and Tb (table 6). However, there was much variation within individual units; the maximum value for each unit was at least 7.8 mg/L and the minimum value was either 0.0 or 0.1 mg/L. Much of this variation is natural and results from reactions between the water and minerals or the water and organic matter.

Specific conductance is a measure of the electrical conductance of the water (corrected for water tempera ture), which increases with the concentration of dissolved minerals. Because of this, specific conductance is a good indication of the concentrations of those dissolved miner als, usually called dissolved solids. The median specific conductance of the samples from 359 wells was 142 \iS/ cm (microsiemens per centimeter at 25°Celsius), and over all the values ranged from 32 to 2,100 \iS/cm (table 5).

Dissolved Solids

The concentration of dissolved solids is the total con centration of all the minerals dissolved in the water. The components of dissolved solids present depend on many factors, but usually include calcium, magnesium, sodium, potassium, bicarbonate, sulfate, chloride, nitrate, and sil ica. Other constituents, such as carbonate and fluoride, or metals such as iron and manganese, are also common but are rarely dissolved in natural waters in large enough con centrations to be a significant contribution to the dissolved-solids concentration.

Dissolved-solids concentrations ranged from 28 to 1,140 mg/L with a median concentration of 112 mg/L (table 5), and the concentrations tended to be larger in the lower (older) units. The median concentration in Qvr was

100 mg/L, and there was a general increase to TQu, where the median concentration was 127 mg/L (table 6). Some of this variation is because of different minerals in the units (Noble and Wallace, 1966), but some likely is due to increased residence time of water in the lower units. Water that has been in the ground for a longer time gener ally has had the opportunity to dissolve more minerals than water with a shorter residence time.

A map of dissolved-solids concentrations (pi. 5) shows some areal variation. Concentrations in the south west, near Black Lake and Littlerock, tended to be less than 100 mg/L; concentrations in the northern and eastern areas were generally more than 100 mg/L. Ground-water residence times would tend to be longer in the north and east, leading to larger dissolved-solids concentrations. Dissolved-solids concentrations exceeding 200 mg/L were observed in the northern parts of all of the peninsulas

(especially Boston Harbor and Johnson Point peninsulas), just south of Mud Bay, and east of Offutt Lake. Most of these large concentrations are from samples of wells near coastal shorelines and are probably associated with seawater intrusion.

Major Ions

Most of the major components of the dissolved-solids concentrations are ions, meaning they have an electrical charge. Cations are ions with a positive charge and include calcium, magnesium, sodium, potassium, and most metals. Anions are ions with a negative charge and include bicarbonate, sulfate, chloride, nitrate, carbonate, and fluoride. Silica has no charge and is the only major component that is not a cation nor an anion.

In Thurston County ground water, the median concen tration of calcium (table 5) was 11 mg/L, the largest of any cation. Magnesium and sodium had median concentra tions of 5.8 and 6.5 mg/L, respectively, and accounted for most of the remaining cations. Concentrations of potas sium, iron, and manganese were generally small compared with calcium, magnesium, and (or) sodium. Maximum concentrations of all these cations were about an order of magnitude larger than the median concentrations.

The major anion was bicarbonate, as indicated by the median alkalinity concentration of 56 mg/L. Although bicarbonate, carbonate, and hydroxide all contribute to alkalinity, at all pH values observed bicarbonate is by far the major component of alkalinity. Thus, at these pH val ues the concentration of bicarbonate is 0.61 times the alka linity concentration, which is expressed as calcium carbonate. The largest alkalinity concentration observed in the study area was 464 mg/L, in a sample from well 19N/01W-32B01. The median concentrations of sulfate, chloride, nitrate, and fluoride were very small compared with alkalinity, and as such they are generally negligible as major components of the water. The maximum concentra tion of chloride, however, was 600 mg/L, and chloride was the major anion in some samples. Chloride and nitrate are discussed in more detail in the next two subsections because of their local effect on water quality.

Silica was also a major component of the dissolved solids, with a median concentration of 35 mg/L. The max imum silica concentration observed was 66 mg/L.

Hardness is calculated from the concentrations of cal cium and magnesium. The most familiar effect of increased hardness is a decreased production of lather from a given amount of soap introduced into the water. Hard water may also cause a scale deposit on the inside of plumbing pipes. Most water samples were classified as soft or moderately hard, as defined by the following scheme (Hem, 1985).

Median concentrations of calcium and sodium were considerably larger in Tb than in the other units (table 6). This is likely a reflection of the different minerals in the bedrock. The variations in calcium and sodium, along with variations in alkalinity and silica, account for most of the differences in dissolved-solids concentrations between geohydrologic units. Variations in median concentrations of magnesium, potassium, sulfate, chloride, fluoride, and nitrate were not large enough to account for much of the variation in dissolved-solids concentrations between units. In fact, median magnesium and potassium concentrations were smallest in Tb, and the median sulfate concentration was smallest in TQu. Median chloride and fluoride con centrations were essentially the same for all units, but median nitrate concentrations decreased from Qvr to Tb.

Chloride

Chloride concentrations for the 359 samples analyzed for common constituents are shown areally on plate 6, along with results from an additional 102 samples col lected from coastal wells as a follow-up to a seawater intrusion study in 1978. Chloride concentrations of the 461 samples ranged from 1.2 to 600 mg/L, with a median concentration of 3.3 mg/L. Median concentrations for each unit varied little, ranging from 2.8 to 4.2 mg/L. These results are very similar to those in tables 5 and 6 for the 359 complete analyses only.

Chloride concentrations of 3.0 mg/L or less were most common in samples from wells in the western part of the study area. However, samples with concentrations exceeding 3.0 mg/L were found throughout the study area. Of particular note is an area southeast of Lacey, in the vicinity of Long Lake and Lake St. Clair, where chloride concentrations for virtually all samples ranged from 3.1 to 5.0 mg/L. Because chloride is a common constituent of septic-tank effluent, these slightly elevated concentrations may have been caused by the large number of homes that rely on such systems in parts of that area.

The highest chloride concentrations exceeded 50 mg/L, and were found mostly along the northeastern and western shores of Johnson Point peninsula, the north ern shore of Boston Harbor peninsula., the northern half of Cooper Point peninsula, the northern end of Griffin penin sula, and the area around the south end of Mud Bay. Con centrations as large as 570 mg/L, in a sample from well 19N/01W- 04G01, were found in these areas. Such con centrations in coastal areas are suggestive of seawater

35

intrusion. However, as shown on plate 6, there are many coastal regions in the study area that had chloride concen trations of 3.0 mg/L or less.

concentrations in the range of 2.1 to 5.0 mg/L, south of Lacey and south of Turn water, were also likely caused by residentially developed areas with septic systems.

Connate seawater seeping from marine rocks of Tertiary age is a likely source of chloride concentrations exceeding 50 mg/L for wells located east of Offutt Lake. Concentrations as large as 600 mg/L were found in that area. The Tertiary Mclntosh Formation is exposed near this area and may also lie at shallow depth beneath other nearby areas, where it is not exposed at land surface. Weigle and Foxworthy (1962, p. 19) and Noble and Wallace (1966, p. 83, 103) pointed out that numerous wells tapping the Mclntosh Formation have produced con nate water that is salty or has otherwise undesirable qual ity.

Chloride concentrations exceeding 5 mg/L in samples collected from wells located away from a shoreline also may be due to contamination from anthropogenic sources such as septic tanks or industry. Road salt is rarely used in Thurston County during the winter and is likely an insig nificant source of chloride.

Nitrate

Nitrate, although not a major component of most water samples, is a concern in some areas of Thurston County because of elevated concentrations and the associ ated implications of ground-water contamination. Con centrations ranged from <0.10 to 19 mg/L, with a median concentration of 0.33 mg/L (table 5). The actual analysis for nitrate includes both nitrite and nitrate; however, nitrite concentrations in ground water are usually negligibly small (National Research Council, 1978). The values determined are therefore considered to be entirely nitrate.

Concentrations of nitrate were 1.0 mg/L or less throughout most of the study area (pi. 6); 71 percent of the samples analyzed fell in this range. The most notable exception is the area east and southeast of Lacey, where virtually all samples had nitrate concentrations above 1.0 mg/L and about half had concentrations exceeding 2.0 mg/L. Concentrations in this area were as large as 7.8 mg/L and likely were due to a high housing density and the extensive use of septic tanks. Agricultural activi ties south of Lake St. Clair may also contribute nitrate to the ground-water system. However, nitrate concentrations were generally small in the agricultural areas themselves, suggesting that the contribution of nitrate from agriculture may be minimal in the area southeast of Lacey. Nitrate

The largest nitrate concentration observed was 19 mg/L, in a sample from well 17N/01W-16E02. This well is only 31 feet deep and located in a pasture, therefore animals or fertilizers are the likely source of the nitrate in this particular well. All other wells sampled in the imme diate vicinity had concentrations of 1.0 mg/L or less, so the problem is not likely widespread. Relatively large nitrate concentrations of 8.3 and 9.9 mg/L were found in samples from wells 17N/01E-11R02 and 17N/01E- 13MO2, respectively. These wells are located about a mile northwest of Yelm, where elevated nitrate concentra tions in ground water are common. There is considerable local debate as to whether the large nitrate concentrations there are due to septic tanks, nearby chicken ranches, or some yet unknown source. Investigating the problem fur ther was beyond the scope of this study because the Yelm area is outside the GWMA.

Nitrate concentrations were generally largest in the shallowest aquifers. The median concentration was 1.7 mg/L in samples in Qvr and generally decreased downward to median concentrations of <0.10 mg/L in both TQu and Tb (table 6). This would be expected, because nitrate sources are typically at or near the surface. Where Qvr is not present or is not saturated, large concen trations may be found in other, older, units.

Water Types

Another way to interpret major ion data is to deter mine the water types (defined by the dominant ions) of the samples from the analytical results. First, concentrations of the major ions are converted from milligrams, which are based on mass, to milliequivalents, which are based on the number of molecules and electrical charge. A milliequivalent is the amount of a compound, in this case one of the ions, that either furnishes or reacts with a given amount of H+ or OH". When expressed as milliequiva lents, all cations or anions are equivalent for the purpose of balancing equations. A milliequivalent of sulfate will combine with a milliequivalent of calcium, as would a milliequivalent of chloride. The milliequivalents of all the cations and anions are then summed separately to obtain a cation sum and anion sum, in milliequivalents. Because the water is electrically neutral, the cation and anion sums should be close in value. The contribution of each ion to the appropriate sum is then calculated as a percentage.

36

The cation(s) and anion(s) that are the largest contributors to their respective sums define the water types. For exam ple, the water type of seawater is sodium/chloride.

To make the determination of water types easier, the percentages of cations and anions for a given sample are plotted on a trilinear, or Piper, diagram (Hem, 1985). The water type is then determined from the area of the diagram in which the sample is plotted (pi. 5). One plot defines the dominant cation, another the dominant anion. Combined water types, where more than one cation or anion domi nate, are possible and are quite common. The diagram shows that to be defined as a sole dominant ion, an ion must account for 60 percent or more of the cation or anion sum, and the analysis will be plotted near one of the cor ners. On the other hand, an ion that accounts for less than 20 percent of the sum will not be included in the water type. An exception to the latter case occurs when two ions are included on a single axis of the plot, such as chloride and nitrate. If both together contribute 20 percent, then the sample will plot as though chloride and nitrate together are dominant anions, even though individually chloride and nitrate contributions may be less than 20 percent. For this study, the actual percentages were used to determine the water type, and if both were less than 20 percent nei ther was considered dominant. Also, for combined water types, the ions are listed in order of dominance. For exam ple, a calcium-magnesium/bicarbonate type has more cal cium than magnesium, and a magnesium-calcium/bicar bonate type has more magnesium than calcium; however, both plot in the same section of the diagram. Note that the diagram, which is based on percentages, does not show actual concentrations.

For this study, all of the samples from a unit were plotted on a common trilinear diagram for each unit (pi. 5); this allowed trends and anomalies to be more eas ily discerned. Samples that plotted away from the major ity of samples for the unit were considered anomalies. They are listed, along with comments, on plate 5. Perhaps the most notable anomalies are the calcium/chloride and sodium/chloride water types; they were observed prima rily in the lower units. Also, a few samples that at first appeared to have bicarbonate-chloride as the dominant anions actually had large nitrate concentrations, which increased the apparent chloride contribution. Most of these samples were from wells in the upper units.

Samples with calcium and (or) magnesium as the dominant cations and bicarbonate as the dominant anion were the most common throughout the study area, and were most common from wells finished in Qvr, Qvt, Qva, Qf, and Qc. Such water types are characteristic of the gla

cial deposits of western Washington (Van Denburgh and Santos, 1965; Turney, 1986a). Freeze and Cherry (1979) attribute those water types to the interaction of dilute, slightly acidic recharge water with aluminosilicate miner als. These minerals dissolve slowly, resulting in low con centrations of dissolved solids and pH values that commonly do not exceed 7.0.

Sodium/bicarbonate and (or) sodium-calcium/bicar bonate water types were common in TQu and Tb. The source of the elevated sodium and bicarbonate concentra tions in some of the water samples from TQu is uncertain, but there are at least two possibilities. The first is that TQu has more sodium-rich minerals than do the overlying younger units. The second is that sodium-rich water flows upward from the underlying Tb. The elevated sodium concentrations in Tb could be caused by geochemical reactions of ground water with basalt, which makes up part of that unit. These reactions have been described by Hearn and others (1985) and by Steinkampf and others (1985) for basalts in eastern Washington, and similar reac tions probably occur in the basalts of Thurston County.

Water types in which chloride is the dominant anion are readily attributed to seawater intrusion if the sample is from a well near a marine water body and finished below sea level. This is obvious for sodium/chloride water types, but even applies to calcium/chloride types and mixed cat ion types, where the proportion of sodium is not as large as would be expected from the proportion of chloride (Piper and others, 1953; Poland and others, 1959).

Chloride water types in samples from wells away from marine shorelines may be attributed to connate seawater in Tertiary marine rocks, such as the Mclntosh Formation of Eocene age. These saline waters likely were trapped in the rock as it was deposited.

Iron and Manganese

Iron concentrations ranged from <3 |ig/L to 21,000 |ig/L, with a median concentration of 23 |ig/L (table 5). Median concentrations for individual units were from 7 to 49 |lg/L for all units except TQu, which had a median concentration of 110 jig/L (table 6). Even so, con centrations exceeding 1,000 |0,g/L were observed in sam ples from every unit except Qvt and Tb. Areal distribu tions of iron concentrations varied, but some patterns are apparent (pi. 6). Large numbers of samples with iron con centrations of 10 |ig/L or less were collected from wells located east and southeast of Lacey, east of Black Lake, and near the town of Rainier. Conversely, large iron con-

37

centrations, some exceeding 300 fig/L, were found in sam ples from wells on the peninsulas and around Lake St. Clair. In general, however, these delineations are subtle, and the concentration of iron is geographically highly variable.

Manganese concentrations ranged from < 1 fig/L to 3,400 fig/L, and the median concentration was 5 fig/L. Like iron, the median concentration for individual units was largest (61 |LLg/L) for samples from TQu; median concentrations for all other units ranged from 1 fig/L to 12 fig/L. The distribution of areal manganese concentra tions followed the same general pattern as iron concentra tions.

The variation and range of iron and manganese con centrations seen in Thurston County are typical of western Washington ground waters (Van Denburgh and Santos, 1965; Turney, 1986a, 1990), and are due largely to natural processes. These processes depend on ambient geochemical conditions, one of which is the concentration of dis solved oxygen. Water that is depleted of oxygen can dissolve iron from the surrounding minerals as the chemi cally reduced ferrous (Fe2 +) form of iron. Iron is highly soluble under these conditions and large concentrations can result. If the water is reoxygenated, then the iron is oxidized to the ferric (Fe3 +) form, which is much less sol uble than the ferrous form and will precipitate as an oxide or a carbonate, resulting in a lower dissolved-iron concen tration (Hem, 1985). Manganese undergoes a similar set of reactions. Because these reactions are oxygen-sensitive and the oxygen content of the ground water may vary con siderably in a given area, dissolved iron and manganese concentrations may also vary greatly.

The large median iron and manganese concentrations in TQu are due in part to the small dissolved-oxygen con centrations in that unit. Water samples from TQu had a median dissolved-oxygen concentration of only 0.2 mg/L, the smallest of any unit (table 6). Although dissolved oxy gen is an obvious factor, this unit may also have more iron- and manganese-rich minerals than do the other unconsolidated units.

Trace Elements

18N/01W-22K01 had a copper concentration of 80 fig/L, which may have leached from the plumbing. The sample from well 18N/01W- 31R02 had an arsenic concentration of 21 ^ig/L, and the sample from well 19N/02W-22D02 had a barium concentration of 12 |Ltg/L. The sources of these latter two large concentrations are unknown.

Concentrations of zinc varied the most, ranging from <3 )Ug/L to 900 |LLg/L (table 7). The areal distribution of zinc concentrations had no discernible geographic trend, and no correlation could be made to geohydrologic units. This is because the most likely source of the zinc is galva nized pipe used in wells and in some home plumbing sys tems. Zinc may be leached from the pipes, especially if the water is slightly acidic and low in dissolved-solids concentration, as is much of the ground water in Thurston County

Concentrations of most trace elements were small. Median concentrations of all trace elements except zinc and radon were less than 5 fig/L (table 7). Only three sam ples had concentrations of any trace element other than zinc or radon larger than 10 fig/L. A sample from well

Radon concentrations ranged from <80 pCi/L (pico curies per liter) to 660 pCi/L, with a median concentration of 410 pCi/L. The picocurie is a measure of radioactivity, not mass. Radon is a naturally occurring element and is part of the radioactive decay chain of uranium. Radon

38

concentrations showed no areal or geohydrologic patterns. The radon concentrations observed in Thurston County are similar to those found in ground water in Clark County (about 75 miles south of Thurston County), where concen trations ranged from <80 to 820 pCi/L, with a median con centration of 315 pCi/L (Turney, 1990). The concen trations are not large compared with some other areas of the Nation, such as Maine, where concentrations in excess of 10,000 pCi/L have been observed in water from granitic formations.

Volatile Organic Compounds

Volatile organic compounds were detected in samples from only 6 of the 46 wells sampled in spring 1989. Sev eral individual volatile organic compounds were detected, but the median concentration of all compounds was less than the detection limit (table 8). The presence of any vol atile organic compound is generally considered to repre sent some type of anthropogenic source. Concentrations of all the detected compounds and the wells from which the samples were taken are listed in table 9.

The largest concentration of any volatile organic com- poand detected was 1.5 |ig/L of 1,2-dichloropropane in a sample from well 17N/01W-02L02. This was the only volatile organic compound detected in the sample col lected from this well in May 1989. The sample from nearby well 17N/01W-02E03 contained 0.8 |ig/L of 1,2-dichloropropane, as well as 0.9 |ig/L of 1,2-dibromoethane (commonly known as EDB) and lesser concentra tions of several other organic compounds. Both wells are located just southwest of Pattison Lake and within 0.5 mile of a strawberry farm and other agricultural activi ties. Because 1,2-dichloropropane and 1,2-dibromoethane are used as pesticides, agricultural activities are suspected as the source of these two compounds. To confirm the results of the May 1989 sampling, and to investigate the presence of an associated pesticide, 1,2-dibromo-3-chloro- propane, both wells were resampled in December 1989. A more sensitive analysis was used for the December sam ples and 1,2-dichloropropane was detected again in both samples, as was 1,2-dibromoethane. The December sam ple from well 17N/01W-02L02 also contained 1,2-dibromo-3-chloropropane. The several other organic com pounds originally detected in the sample from well 17N/ 01W-02E03 were not detected in the December 1989 sam ple. This may be related to instrument problems that occurred during the analysis of the original sample and is discussed in Appendix B.

Small concentrations of trichloromethane and bromodichloromethane were found in samples from well 18N/01W-02G02, as were trace concentrations of trichlo romethane in the sample from well 18N/01W-17H05. These compounds are usually associated with industrial or commercial activities or the chlorination of drinking water. The samples were not chlorinated, however. Trace concentrations of 1,1,1-trichloroethane were found in sam ples from well 18N/01 W-l 1P05 and are likely related to commercial activities, such as automotive repair or dry cleaning. Benzene, dimethylbenzene, and ethylbenzene were detected in samples from well 18N/01W-06A03 and are characteristic of gasoline contamination. None of these wells were resampled as part of this study to verify the small concentrations because they are public-supply wells that will be monitored by another agency in the future.

Septage-Related Compounds

Concentrations of boron, DOC (dissolved organic car bon), and MBAS (methylene blue active substances) were determined for samples from 44 wells located mostly in areas with septic systems. Boron and MBAS are present in household wastewater as detergent residues and have been identified in septage-contaminated ground water (LeBlanc, 1984). Large concentrations of DOC may sug gest the presence of several types of organic compounds, including septage compounds, oil and grease, and sol vents.

The median concentration of MBAS in the samples was 0.03 mg/L, and the maximum concentration was 0.21 mg/L (table 10). The median concentration is larger than the median concentration of 0.01 mg/L reported for ground waters in Clark County (Turney, 1990) and south western King County (Woodward and others, 1995). The median value is also slightly larger than the concentration of 0.02 mg/L, above which ground-water quality can be considered degraded, as suggested by Hughes (1975). All MBAS concentrations in Thurston County exceeding 0.04 mg/L were in samples from wells in unsewered areas, and half of these were in areas with more than 250 resi dential units per square mile. Water from well 18N/ 01W-11P05, which had an average MBAS concentration of 0.08 mg/L, also contained 1,1,1-trichloroethane. All wells with water samples having MBAS concentrations exceeding 0.04 mg/L are listed in table 11.

'Two samples collected in December 1989 had a minimum concentration of 0.12 |ig/L because a more sensitive method was used. The detection limit of the method used to analyze the samples collected in the spring of 1989 was 0.2 |ig/L.

The major source of the MBAS concentrations observed is believed to be septic tanks. The only other potential source is surfactants, which are also detected as MBAS and are used in pesticide applications for agricul tural activities. The typical agricultural usage, though, is only a few ounces per 100 gallons of pesticide/water solu tion, which is spread over several acres. Because applica tions are generally made only once or twice a year, a reasonable estimate of agricultural application is about 1 ounce per acre per year. This is a small amount com pared with the amount of laundry detergent used in just one household. Conservatively assuming 8 ounces of detergent used per week per household and a density of 250 residential units per square mile, the load of deter gents from septic tanks could easily be as large as 160 ounces per acre per year.

In samples analyzed for concentrations of both nitrate and MBAS, the correlation coefficient between these two constituents is 0.85 (fig. 14). This degree of correlation implies that sources of nitrate and MBAS are similar. Whereas nitrate may have several sources including agri cultural activities and septic systems, the only large source of MBAS is septic systems. Therefore, much, but not nec essarily all, of the nitrate in the ground water of the unsewered, densely populated areas is also likely to be from septic systems.

The median concentration of boron was 10 |ig/L. Samples from only 7 of the 44 wells had concentrations exceeding 20 |ig/L (table 11). Six of the 7 wells were located in high-density residential unsewered areas with more than 250 residences per square mile. It would seem, therefore, that even these slightly elevated boron concen trations might be associated with septic systems. How ever, boron concentrations correlated poorly with nitrate and MBAS concentrations; good correlations would have been expected if septic systems were the true source. It is possible that boron may be transported by ground water differently than nitrate and MBAS, or that the elevated boron concentrations are merely due to natural causes. Natural boron concentrations in excess of 100 |ig/L are not uncommon (Hem, 1985).

Most DOC concentrations were 1.0 mg/L or less. The median concentration was 0.4 mg/L, smaller than the value of 0.7 mg/L given by Thurman (1985) as the median concentration of DOC in ground waters throughout the United States. Samples from only four wells had concen trations exceeding 1.0 mg/L (table 11) and the maximum concentration was 3.1 mg/L. Of these four samples, one from well 18N/02W-04J08 also had a large boron concen tration (70 |ig/L), but boron concentrations in the other three samples, and nitrate and MBAS concentrations in all four samples, were not large (table 11). Overall, the corre lations of DOC with nitrate, MBAS, and boron were poor. Given the diversity of sources and the lack of correlation with other septage-related compounds, it is difficult to attribute these few large concentrations of DOC to septic systems. In addition to the anthropogenic sources of DOC mentioned, there are several natural sources, includ ing recent surficial organic matter and kerogen, the fossil ized organic matter present in most aquifer materials (Thurman, 1985).

Bacteria

Bacteria were present in samples from 20 of the 359 wells and springs. Fecal coliform were present in 2 sam ples and fecal streptococci in 15 samples; 3 samples con tained both types of bacteria. Median concentrations of fecal coliform and fecal streptococci bacteria were both less than 1 colony per 100 milliliters (table 12). Both types of bacteria are merely indicators; that is, they are not pathogenic themselves, but can occur in conjunction with pathogenic bacteria. Fecal coliform are the only bacteria for which a quantitative relation with a pathogen (salmo nella) has been observed (Geldreich and Van Donsel, 1970).

Figure 14. Comparison of nitrate and methylene blue active substances (MBAS).

The sites that contained bacteria are listed in table 13. The only results that are readily explainable are those for Abbott Springs (18N/01E-19J01S) and Allison Springs (18N/02W-18L01S). Samples from both springs were col lected from ponds into which the springs discharge. These ponds are easily accessible to and extensively used by wildlife such as ducks, which are prolific sources of bacte ria. The sources of bacteria in wells are more difficult to determine. Seme of the wells containing bacteria, includ ing 16N/02W-27H02, 19N/01W-18F01, and 19N/01W- 29C02, are located near barns, which suggests that farm animals may be the source of the bacteria. Other wells may be near septic tanks, another potential source of bac teria. However, nitrate concentrations in most bacte ria-contaminated wells were less than 1.0 mg/L, suggest ing a source other than septic systems or animal wastes. Regardless of the source(s), the presence of bacteria in ground water in Thurston County was limited, and no areal patterns were evident.

Drinking Water Regulations

The USEPA has established drinking water regula tions with several sets of laws and legislation. These regu lations may be considered in two groups. Primary drinking water regulations generally concern chemicals that affect human health. The maximum concentration allowed for each constituent is referred to by USEPA as the maximum contaminant level, or MCL (U.S. Environmental Protection Agency, 1988a, 1988b, 1989), and is legally enforceable by the USEPA or State regula tory agencies. Secondary drinking water regulations (U.S. Environmental Protection Agency, 1988c) pertain to the esthetic quality of water and are guidelines only. A sec ondary maximum contaminant level, or SMCL, is not enforceable by a Federal agency. Both sets of regulations legally apply only to public supplies, but can also be used to help assess the quality of private systems.

The drinking water regulations for all constituents determined in this study are shown in table 14. Because the regulations are subject to revision, this report uses the MCL or SMCL in effect at the time the samples were col lected. Along with each MCL or SMCL, the number of wells from which samples did not meet the regulation is also shown in table 14.

The only primary MCL that was not met was the one for nitrate, in one sample from well 17N/01W-16E02, which had a nitrate concentration of 19 mg/L. Although less than the MCL of 10 mg/L, the nitrate concentration in well 17N/01E-13M02 was 9.9 mg/L. The nitrate MCL is

based on the concentration that can cause methemoglobin- emia in infants. This disease can result in suffocation because the oxygen-carrying capacity of hemoglobin is impaired by large concentrations of nitrate in the blood. Older children and adults generally are not affected at these levels.

Although total coliform bacteria were not analyzed for, the presence of fecal coliform bacteria in samples from five sites implies that the MCL for total coliform was exceeded. The presence of fecal coliform bacteria sug gests some type of fecal contamination, and as such is con sidered a drinking water problem.

The most important SMCL's that were not met may be those for chloride and dissolved solids, because large con centrations of these constituents in ground waters in the study area usually suggest seawater intrusion. The chlo ride SMCL of 250 mg/L was not met in samples from 11 of 461 wells, or 2 percent. Of these, 5 wells were from the group of 359 sampled for all common constituents, and 6 were from the 102 coastal wells sampled for chloride only. Only one of the 11 wells, 16N/02W-05R01, was located far enough from the coast that intrusion was unlikely. This is the well believed to be affected by connate seawater from the Mclntosh Formation. The SMCL for chloride is the level at which the taste of the water may be affected.

Of the six water samples that did not meet the dissolved-solids SMCL of 500 mg/L, five also did not meet the chloride SMCL. The large dissolved-solids concentra tion in the sixth well, 19N/01W-32B01, most likely was due to a large alkalinity concentration. Four of the five wells that also did not meet the chloride SMCL were prob ably intruded with seawater. The exception was well 16N/ 02W-05R01, likely affected by connate seawater. Like chloride, the SMCL for dissolved solids is based largely on taste, although other undesirable properties such as cor- rosiveness or hardness may be associated with large dis solved-solids concentrations.

More samples did not meet the SMCL for manganese (50 |J.g/L) than for any other constituent: samples from 107, or 30 percent, of the 359 wells sampled. However, as described elsewhere, these large manganese concentra tions occur naturally and are common. The SMCL for manganese is based on the level at which staining of laun dry and plumbing fixtures may occur; the stain is usually black or purple. The taste of the water may also be affected at concentrations greater than 50 |J.g/L. Extremely large concentrations of manganese may cause human health problems, but no such instances have ever been reported in the United States (U.S. Environmental Protection Agency, 1986).

Concentrations of iron in samples from 57 wells, or 16 percent, did not meet the SMCL for iron of 300 |J.g/L. As with manganese, these large concentrations are likely due to natural causes. Iron concentrations exceeding the SMCL may cause objectionable tastes and may stain plumbing fixtures a characteristic red or brown color. Some industrial applications, such as paper production, food processing, and chemical production, may require concentrations less than 300 |J,g/L.

Samples from 34 wells, or 9 percent, had pH values outside the acceptable range of 6.5 to 8.5 (U.S. Environmental Protection Agency, 1986). Of these, 29 had values less than 6.5 and 5 had values greater than 8.5. Samples from another 19 wells had pH values equal to 6.5. A broader pH range from 5 to 9 is often considered accept able for domestic supplies because water in this range is readily treatable (U.S. Environmental Protection Agency, 1986). Samples from only four wells were above this range and none had a pH value below this range. Small pH values may be corrosive to pipes and plumbing and can increase copper, lead, zinc, and cadmium concentra tions. Large pH values may adversely affect the chlorination process and may cause carbonate to deposit in pipes.

All other applicable USEPA drinking water regula tions were met. Note, however, that even though the MCL for a particular regulation was met, the constituent may have been present in concentrations smaller than the MCL, indicating a potential water-quality problem. This is espe cially true for the organic compounds 1,1,1-trichloroethane, 1,1-dichloroethene, trichloroethene, benzene, and MB AS. As discussed previously in this report, the nature of these compounds is such that their mere presence indi cates some degree of contamination.

For more information on drinking water regula tions, the reader is referred to documents of the U.S. Environmental Protection Agency (1976, 1986, 1988a, 1988b, 1988c, 1989).

Variations of Water Quality at Times of High and Low Water Levels

Samples were collected from 26 wells and 2 springs in the area between McAllister Springs and Lake St. Clair during November 1988, before the entire study area was sampled in spring 1989. These samples were collected to provide background data from the McAllister Springs area for the Thurston County Health Department. Because 23 of the 26 wells and the 2 springs (Abbott and McAllister) were resampled in the 1989 effort, the variation of water quality at times of high and low water levels can be exam ined for this area.

In general, there were no large differences between constituent concentrations in samples collected in late 1988 and in early 1989. Most of the paired concentrations (from 1988 and 1989) differed by less than 10 percent. For some constituents, such as dissolved oxygen, sulfate, nitrate, and iron, concentration pairs from several wells differed by more than 10 percent, but for most of these

47

cases, concentrations were small and the absolute differ ence in concentration also was small. Even when the dif ferences were considered large, such as for the nitrate data (table 15), the differences appear to be limited to specific wells, and no areal trend could be discerned. The data from each well sampled in November 1988, along with data collected from these same wells in spring 1989, are listed in Appendix C.

Although differences in these samples are few, there still may be some unobserved seasonal variations or long-term trends in the study area. Only two data points have been considered for each of the wells discussed, and usually more data are needed to discern seasonal varia tions. Many more data over several years are needed to determine trends.

Water-Quality Problems

Several occurrences of large concentrations of certain constituents in the ground waters of Thurston County have been identified and attributed to one or more sources. Some of these large concentrations are a health concern; others affect only the esthetic qualities of the water. In either instance, a water-quality problem or concern exists, and to understand the problem it is helpful to understand its source, if known, and how it affects water quality and water chemistry. A complete description of all the sources of water-quality problems in Thurston County is beyond the scope of this report. However, brief discussions of the more important ground-water quality problems are pre sented below. The extent and severity of water-quality

problems depend not only on the source, but on many geohydrologic conditions, including aquifer mineralogy, ground-water flow direction and rate, depth to water, recharge rate, and water chemistry.

Seawater Intrusion

Wells in coastal areas are at risk of pumping some seawater because the ground water at depth in these areas may consist partly, or wholly, of water from Puget Sound. In addition to larger concentrations of sodium and chlo ride, intrusion of seawater into wells can also lead to increased concentrations of calcium, magnesium, potas sium, sulfate, barium, and some trace elements. Once seawater intrudes an aquifer, it may be difficult and expensive to control or reverse the condition. Because ground water moves slowly, remedial measures may require years or decades to take effect.

In about 1900, hydrologists working along coastal areas of Europe observed that seawater occurred beneath fresh ground water not at sea level, but at a depth below sea level of about 40 times the height of the freshwater above sea level. The freshwater appeared to "float" on the seawa|er as a lens- or wedge-shaped body. This relation, known as the Ghyben-Herzberg principle after the two sci entists who first described it, occurs because the density of freshwater is slightly less than the density of seawater. The principle assumes static ground-water conditions and a sharp boundary between freshwater and saltwater.

The result of this effect is somewhat different for Puget Sound, where the water is slightly more dilute and less dense (1.020 grams per milliliter) than typical seawa ter (1.025 grams per milliliter) due to freshwater inflow (Wagner and others, 1957). Applying the Ghyben- Herzberg principle to locations along Puget Sound, for every 1 foot of altitude that the water table is above sea level, fresh ground water will extend about 50 feet below sea level. For example, if the water table at a given site is 3.0 feet above sea level, the freshwater-seawater boundary is theoretically 150 feet below sea level. The thickness of the freshwater body is, therefore, 153 feet at that site. The principle also implies that if the water table in an aquifer is lowered 1 foot, the boundary will rise 50 feet, thereby reducing the total thickness of the freshwater layer by 51 feet.

In addition to the relative densities of freshwater and seawater, the position of the boundary at any one time is also affected by tides, the seasonal position of the water table, the hydraulic characteristics of the aquifer, and recharge-discharge relations within the aquifer. The

48

boundary is seldom sharp, but rather is a "zone of transi tion" in which the chloride concentration gradually increases from that of freshwater to that of the surrounding salt water body. This zone may be narrow or broad, depending on the hydraulic characteristics of the aquifer and other factors. Because the position of the boundary is a function of recharge, discharge, and the spatial variation of aquifer hydraulic characteristics, the Ghyben-Herzberg principle should only be used to provide an approximate position of the transition zone.

Under natural conditions, the altitude of the water table in a coastal area is higher than sea level and decreases toward the shoreline; if recharge and discharge are in equilibrium, the boundary (zone of transition) is maintained in a relatively constant position (fig. 15). Freshwater under these conditions will move downgradi- ent toward the sea and eventually, if not intercepted by pumping wells, discharge to low-lying coastal areas and to the sea. When the freshwater gradient is decreased or reversed, such as by pumping from wells, the seaward flow of freshwater is decreased and the boundary moves landward and upward. Conversely, when water levels increase, the boundary moves seaward and downward.

The saline water surrounding the Thurston County shoreline typically contains about 15,000 mg/L of chloride (Wagner and others, 1957); uncontaminated ground water in most coastal areas of Washington generally contains less than 10 mg/L of chloride (Dion and Sumioka, 1984). Chloride is chemically stable and will move through the saturated zone of an aquifer at virtually the same rate as intruding seawater. For this reason, chloride serves as a good indicator of seawater intrusion.

In this study, chloride concentrations were 5 mg/L or less in samples from 77 percent of all wells. This concen tration can be considered a maximum "background" level. Concentrations in excess of 5 mg/L may be due to intru sion, but only if the samples are from wells completed below sea level and located along the coast. Twenty-nine of 73 samples with chloride concentrations from 5.1 to 50 mg/L can be attributed to such coastal wells; the other 44 samples came from wells too far inland to be intruded. The chloride concentration at which a well is intruded is uncertain but is likely within this range. Thus a chloride concentration of 50 mg/L was conservatively selected as the level above which a coastal well can be considered intruded. Of 32 samples with chloride concentrations larger than 50 mg/L, 25 were from coastal wells.

The coastal areas where chloride concentrations in some wells exceeded 50 mg/L were identified previously as the northeastern and western shores of Johnson Point peninsula, the northern shore of Boston Harbor peninsula,

the northern half of Cooper Point peninsula, the northern end of Griffin peninsula, and the area around the southern end of Mud Bay (pi. 6). Seawater intrusion does not appear to occur selectively in any particular geohydrologic unit (among the units present along the shorelines) or at any particular depth or altitude. Intrusion occurs in both Qc and TQu, the units most heavily pumped along the coast. Chloride concentrations larger than 50 mg/L occurred in wells completed at altitudes (horizons) of -12 to -235 feet (relative to sea level).

Samples from coastal wells completed at similar alti tudes and near each other were found to have widely vary ing chloride concentrations. Samples from wells 19N/ 01W-10L02 and 19N/01W-10Q02 had chloride concentra tions greater than 300 mg/L; however, the sample from well 19N/01W-15G01, which is about half a mile south, had a concentration of only 3.0 mg/L. All three wells are completed at altitudes of -40 to -55 feet, the first two in Qc and the latter in TQu. Likewise, a sample from well 19N/ 01W-20G01 had a chloride concentration of 92 mg/L, but a sample from well 19N/01W-20R03 had a concentration of only 1.2 mg/L. Both wells are completed in Qc at alti tudes 19 feet apart. It is evident that the occurrences of intrusion can vary widely and are probably affected more by pumping patterns and (or) heterogeneities in local geo logic conditions than by regional geohydrologic features.

The degree of intrusion does not appear to be chang ing significantly with time over widespread areas. Except for Johnson Point peninsula, all of the areas identified as being intruded in this study were also identified by Noble and Wallace (1966) as being intruded in 1961. A compar ison of chloride concentrations in samples collected from 112 wells sampled during this study and in 1978 (Appen dix C, table C6) showed that concentrations in samples from 57 wells differed by 10 percent or less (table 16). The differences for another 29 wells were greater than 10 percent, but chloride concentrations were 5.0 mg/L or less for both samples, so the actual concentration differ ences were small. Only 26 pairs differed by more than 10 percent and had concentrations larger than 5.0 mg/L. Interestingly, of these 26, 12 showed an increase from 1978 to 1989 and 14 showed a decrease. Of 17 pairs where concentrations were more than 50 mg/L, signifying seawater intrusion, 11 differed by more than 10 percent; however, 7 showed an increase and 10 showed either a decrease or no change. Overall, samples from 57 wells showed an increase and samples from 55 wells either a decrease or no change. No clear direction or magnitude of change is apparent. This comparison does not take into consideration any natural seasonal, tidal, or other cyclical variations in concentration. Changes in the degree of intrusion for an individual well may be more or less than that determined by this limited comparison.

Agricultural Activities

Agricultural activities can lead to several types of water-quality problems, most commonly the presence of various nitrogen species, pesticides and associated com pounds, and bacteria. Sulfate, chloride, and phosphorous also may be present. Most problems are related to fertiliz ers, pesticides, or barnyard wastes.

Virtually all fertilizers include some type of nitrogen in the form of ammonia or nitrate. In some, the nitrogen is part of a solid organic compound and is released over sev eral days or weeks to the soil; in others an aqueous solu tion of nitrogen, usually as ammonia, is injected directly into the soil and is released immediately. Any ammonia is usually converted by bacteria to nitrite and then to nitrate in the process of nitrification. Nitrate, whether applied or converted from ammonia, then is taken up by the crops. Any remaining nitrate can be transported by water perco lating down through the soil and the unsaturated zone to the water table. Nitrate generally does not sorb, or attach, to the aquifer material, therefore it is transported at a rate

similar to that of the ground water. In some instances, unconverted ammonia may be transported to the ground water also, either as ammonium ion or as an organic ammonia compound. Ammonia tends to sorb to soil parti cles, so it may not be transported as quickly as nitrate. Usually, any ammonium or ammonia compound reaching the ground water ultimately will be converted to nitrate. Fertilizers also contain other chemicals that may be intro duced into the ground water, such as potassium, sulfate, and phosphorous, but the resulting concentrations are usu ally small compared with those of nitrate.

Barnyard wastes, including those from dairies and feedlots, contain urea, chloride, and bacteria, along with other constituents in smaller quantities. Urea eventually is converted to nitrate, which is transported in the aquifer in a manner similar to nitrate from fertilizers. Chloride is generally unreactive and will also be transported to the water table. Many different types of bacteria are present in barnyard wastes, including the indicator bacteria (fecal coliform and fecal streptococci) analyzed for in this study. Their viability while being transported to and within the

51

ground water depends greatly on such factors as water temperature and depth to water. Sodium, potassium, sulfate, and phosphorous are among the other constituents that may also be transported to the ground water from barnyard wastes, but natural sources generally mask these contributions.

The transport of pesticides and their associated com pounds to the ground water is complex. Most pesticides undergo chemical and biological transformations as part of one or more of the following processes: biodegradation, photolysis, hydrolysis, or oxidation. The products of these reactions may be as great a contamination problem as the original pesticide. Also, solvents or carriers, such as tolu ene, are applied with pesticides to assure an even applica tion of the pesticide. The transport of all these pesticide- related compounds is affected by physical processes such as dissolution in the water, sorption to aquifer material, and volatilization to the atmosphere as soil gas. Because of these factors of pesticide transport and all of the geohydrologic variables, the occurrence of pesticides in ground water can vary widely over both space and time. Addi tionally, pesticides can remain a water-quality problem for many years.

The most serious agriculture-related water-quality problem identified during this study was the presence of pesticides in ground water. The pesticides 1,2-dibromoethane (EDB), 1,2-dichloropropane, and 1,2-dibromo-3- chloropropane were detected in samples from wells along the southwestern shore of Pattison Lake. These same pes ticides were previously reported in samples from wells about 3 miles east, just south of Lake St. Clair, in an area where the pesticides had been applied on strawberry fields. In this latter case, alternative water supplies were required for several residences with contaminated wells. (The pres ence of EDB near Lake St. Clair was not investigated as part of this study because it had been addressed as part of another study and was under litigation at the time.)

Barnyard wastes probably contributed to elevated nitrate concentrations in some small areas. However, large areas of elevated nitrate concentrations, such as those east and southeast of Lacey, are not likely due to agricultural sources, but rather to septic systems. Isolated bacterial problems in the general study area may also be due to barnyard wastes.

A group of agricultural activities that was outside the scope of this study and is not included in the above assess ment is sometimes referred to as "hobby farming." This includes agricultural activities similar to those discussed, but on a smaller scale for private rather than commercial

use. Examples include backyard gardens, pet pens or cor rals, and lawns. Most hobby farms are in suburban or urban areas, and as such are not considered commercial agricultural activities. However, pesticide and fertilizer use is extensive and these chemicals are often overapplied because of a lack of knowledge, experience, or motive for cost effectiveness. Little documentation has been done on hobby farming, but researchers have reported that urban lawn fertilizers may contribute as much nitrate to ground water as do septic systems (Porter, 1980).

Septic Systems

A septic system, consisting of a septic tank and drainfield, can be a source of several constituents in ground- water. The most familiar of these is nitrate, but others include sodium, potassium, sulfate, chloride, phosphorous, ammonia, boron, MBAS, and bacteria. Because septic systems are used virtually everywhere that central sewer systems are not available, they are a widespread source of these constituents and may remain so long after they are abandoned.

In the operation of a septic system, household sewage is piped into a tank that typically has a capacity of approx imately 1,000 to 1,500 gallons for a single household unit. In the tank, solids settle to the bottom and liquids dis charge to a drainfield, which is a subsurface trench filled with permeable material such as sand or gravel. The drainfield allows the liquid to infiltrate the natural soil or geologic formation over a large area. Ultimately, the efflu ent percolates down through the unsaturated zone. Where septic tanks are used in densely populated areas, the com bined discharge from them may be a large component of the total ground-water recharge.

Once in the unsaturated zone, the individual constitu ents in the effluent are susceptible to the same chemical and biological transformations as constituents that origi nate at land surface. Urea is transformed by bacteria to ammonia and eventually to nitrate. The nitrate, along with chloride, then flows through the aquifer at virtually the same rate as the ground water. Sodium, potassium, sul fate, MBAS, and other constituents, however, may undergo sorption, ion exchange, or degradation reactions that can hinder their transport to and within the ground- water body.

The good correlation between MBAS and nitrate con centrations (fig. 14) suggests that septic systems were the source of much of the nitrate found in Thurston County ground water. As discussed in previous sections, the large

52

areas where nitrate concentrations were in excess of 2.0 mg/L are, for the most part, densely populated areas where septic systems are common. Isolated concentra tions of nitrate in excess of 1.0 mg/L may be from individual septic systems, but could also be from local agricultural activities.

Commercial and Industrial Activities

Many widespread commercial and industrial activities in Thurston County use chemicals that are potential sources of ground-water contaminants. Service stations are potential sources of benzene and other hydrocarbon compounds from fuels and oils. Dry cleaners and paint shops are potential sources of solvents such as 1,1,1- trichloroethane and trichloroethene. Solvents, along with metals such as chromium, copper, zinc, and lead, can come from electronic, machine, and automotive-repair shops. Parking lots and roads may also be sources of many of these chemicals. In general, most of the chemi cals are volatile organic compounds or trace elements. Industrial activities such as shipping, manufacturing, and food processing can also be sources of these chemicals, but there are few of these activities in Thurston County.

Chemicals are sometimes spilled or dumped onto the ground, where they are dissolved or otherwise incorpo rated into the recharge water. In the case of large spills of liquids, such as fuels or oils, the chemical itself may travel into the unsaturated zone unaltered. In other instances the chemical may reach the ground water only after being sub jected to physical or chemical transformation processes, such as volatilization, sorption, biodegradation, hydroly sis, or oxidation. As a result, the contaminants in ground water may eventually include any of the initially spilled compounds or their transformation products.

Contamination of ground water in Thurston County by commercial and industrial activities was apparently minimal at the time these samples were collected. Of six samples found to contain volatile organic compounds, four were from wells located north and east of Lacey in com mercial or industrial areas. Potential sources of the chem icals are different for each well and were likely from the types of activities described in this section. No large con centrations of trace elements were associated with these activities.

Because this study was designed to determine large- scale areal variability, it is unlikely that all areas of con tamination by commercial and (or) industrial activity in northern Thurston County were discovered. Sources are

generally isolated, therefore areas contaminated as a result of commercial or industrial activity are typically small. On the scale of this study, the areal density of sampled wells was too low to detect small contaminated areas.

Natural Conditions

Most of the water-quality problems in the study area were attributable to natural conditions. Large concentra tions of iron and manganese are the most widespread natu ral problems. Connate water with large chloride concen trations is another naturally occurring water-quality prob lem. Fortunately, most of these problems are esthetic and not health threatening.

BENEFITS OF MONITORING AND POSSIBLE ADDITIONAL STUDIES

The long-term effects of various ground-wafer man agement alternatives and of changing land-use conditions in northern Thurston County could be monitored by the establishment of a water-level measurement and water-sampling network. Water-level declines beyond those expected for seasonal or climatic reasons could pro vide an early warning of ground-water overdrafts; water-quality degradation could indicate the need to revise land-use controls or other management practices.

A long-term cost-effective monitoring program would include measuring water levels in selected wells every 2- 3 years in spring and autumn, corresponding to times when water levels in shallow wells are at their seasonal highs and lows, respectively. One-third of the wells could be measured annually. More frequent measurements could be made as desired or needed. The aquifers of great est concern would be those that are the most heavily used for ground-water supplies. Observation wells could be selected to provide broad geographic coverage of the aqui fers of concern, with emphasis on the areas of greatest ground-water withdrawal.

A minimum water-quality monitoring program would include the periodic collection of samples for the analysis of nitrate, chloride, and bacteria. An expanded program could include analyses for concentrations of common ions, trace elements, and organic compounds (including pesti cides). Samples would be collected from the areas east and southeast of Lacey, immediately upgradient of McAllister Springs, and in rapidly growing residential areas that depend on septic systems, to determine the tem poral trends of nitrate concentrations.

53

Samples from coastal wells finished below sea level would be analyzed for chloride concentrations in order to detect incipient seawater intrusion. A gradual increase in chloride concentrations with time, or concentrations in excess of normal seasonal highs, could be interpreted as evidence of seawater intrusion.

The monitoring program proposed above would be reviewed periodically to evaluate the number and loca tions of wells and the frequency of their measurement and sampling. This evaluation would reflect changing cul tural, managerial, and hydrologic conditions. Modifica tions could be made, but ideally would be kept to a minimum because the long-term success of a monitoring program depends in part on continuity.

The large chloride concentrations thought to be asso ciated with marine rocks could be investigated further. In particular, additional wells in the vicinity of Offutt Lake could be sampled to determine the extent of the large chlo ride concentrations, and a more thorough study made to determine the cause.

The occurrences of moderate concentrations of vola tile organic compounds in samples from six wells in the eastern part of the study area could be investigated in greater detail. Individual, focused studies would be needed for each occurrence.

Although excessive concentrations of iron and man ganese pose no health risk and are controlled primarily by natural geochemical reactions, their presence is annoying and considerable time and money is spent by well owners to avoid or minimize their effects. A study to determine the specific conditions and processes that contribute to large iron and manganese concentrations in western Wash ington would be of interest.

SUMMARY AND CONCLUSIONS

Northern Thurston County is underlain by as much as 1,800 feet of unconsolidated glacial and nonglacial depos its of Pleistocene age. Beneath these unconsolidated deposits is bedrock, composed of consolidated rocks of Eocene to Miocene age. Interpretation of 17 preliminary geologic sections and about 1,140 drillers' logs led to the delineation of 7 major geohydrologic units. Six of the geohydrologic units are in the unconsolidated deposits. In general, the unconsolidated deposits are lithologically var ied and most geohydrologic units have limited vertical and lateral extent. More than 90 percent of the wells used to

collect geologic and hydrologic data for this study are completed in the uppermost 250 feet of the Quaternary deposits.

Although four coarse-grained geohydrologic units (Qvr, Qva, Qc, and TQu) function as the principal aquifers of the study area, usable quantities of ground water can also be obtained from units Qvt, Qf, and the bedrock (Tb). Even though the fine-grained units generally function as confining beds, numerous wells produce water from thin, local lenses of sand or gravel within them.

Water-level data indicate that ground water in the principal aquifers of the study area generally moves later ally to the marine shoreline and to major surface drainage channels. Beneath the upland areas, ground water has a downward vertical component; along the marine shore lines and the major drainage channels, ground water has an upward vertical component.

Discharge from the ground-water system occurs as seepage to streams, springs, and coastal bluffs; as evapora tion from soils and transpiration by plants; as underflow (submarine seepage to Puget Sound and flow to ground water outside of the study-area boundary); and as with drawals from wells.

More than 33,000 acre-ft/yr of ground water dis charges as springs from the GWMA. Approximately 21,000 acre-feet of water was withdrawn from the ground-water system of the GWMA through wells in 1988. Total ground-water use was approximately 37,000 acre-ft. About 16,000 acre-feet of the water that discharges through springs was used together with water withdrawn by wells for domestic supply, agricultural, commercial, industrial, institutional, and aquaculture and livestock uses.

The chemical quality of ground water in the study area is generally good, and 94 percent of the water sam ples were classified as soft or moderately hard. Dis- solved-solids concentrations tended to be higher in the lower units as is typical of glacial deposits in western Washington. The major cations were calcium and magne sium and the major anion was bicarbonate. Calcium/ bicarbonate and calcium-magnesium/bicarbonate were the most common water types.

Perhaps the most widespread anthropogenic water-quality problem is seawater intrusion, which has resulted in local chloride concentrations as large as 570 mg/L. For this study, areas in which seawater has intruded were defined as coastal areas where concentra-

54

tions of chloride exceeded 50 mg/L. Such concentrations were found on the northeastern and western shores of Johnson Point peninsula, the northern shore of Boston Harbor peninsula, the northern half of Cooper Point penin sula, the northern tip of Griffin peninsula, and near the southern end of Mud Bay. However, there are many coastal areas where no intrusion is evident. A comparison with data from 1978 gives no indication that the degree and extent of intrusion have changed significantly in the sampled wells since that time.

Agricultural activities may be responsible for the presence of pesticides in samples from two wells south west of Pattison Lake. The pesticides detected were 1,2-dibromoethane (EDB), 1,2-dichloropropane, and l,2-dibromo-3-chloropropane, and are the same ones pre viously detected in samples from wells about 3 miles east, south of Lake St. Clair. Barnyard wastes may contribute to elevated nitrate concentrations locally and to isolated bacteria problems. However, large areas of elevated nitrate concentrations likely are not a result of agricultural activities.

Septic systems are probably the largest contributors of nitrate to the ground-water system of northern Thurston County. Even though the median nitrate concentration was 0.33 mg/L, some areas have nitrate concentrations in excess of 2.0 mg/L. These areas are east, southeast, and south of Lacey, and south of Tumwater, and all areas of relatively high housing density and septic tank use. Con centrations of detergents correlated well (correlation coef ficient of 0.85) with nitrate concentrations, implying a common source. Because septic tanks are the only major source of detergents, this correlation is evidence that much of the nitrate likely comes from septic systems.

Most water-quality problems in northern Thurston County result from natural causes. Iron concentrations were as large as 21,000 }J.g/L, and manganese concentra tions were as large as 3,400 |ig/L. At these levels, the taste of water may be adversely affected and plumbing fix tures may be stained red, brown, or black. These problems were evident throughout the county and are common in western Washington ground waters. These large concen trations are due largely to the dissolution of naturally occurring iron and manganese in the aquifer minerals.

Another natural water-quality problem is the presence of connate seawater in the southern part of the study area. There, Tertiary marine rocks of the Mclntosh Formation, which are naturally high in chloride, are exposed or are

just beneath the surface. Water from this formation proba bly flows into the overlying unconsolidated deposits, caus ing varying degrees of salinity in some wells.

Concentrations of selected constituents were com pared with maximum contaminant levels, or MCLs, for applicable USEPA drinking water regulations. The only primary MCL that was not met in all cases was the one for nitrate, which is 10 mg/L. The secondary maximum con taminant level (SMCL) of 250 mg/L for chloride was not met in samples from 11 of 461 wells (2 percent), 10 of which were from wells most likely affected by seawater intrusion. More samples did not meet the SMCL for man ganese than for any other standard. Some 30 percent of all wells had samples that did not meet the manganese SMCL of 50 |ig/L. Likewise, 16 percent did not meet the SMCL of 300 |ig/L for iron.

APPENDIX B

Quality-Assurance Assessment of Water-Quality Data

The quality-assurance plan for this study (G. L. Turney, U.S. Geological Survey, written commun., 1989) calls for quality-control procedures at all levels of data collection and analysis. Whereas many of the procedures address only methodology, some require the collection and analysis of quality-control samples. The resulting data are reviewed to determine the quality of the project data.

The water-quality data used in this study were good by most measures. Errors associated with most standard and duplicate samples were within project criteria for most constituents. Exceptions occurred where constituent con centrations were near detection limits and small absolute errors resulted in large percentage errors. Concentrations in blanks, various internal sample checks, and compari sons of field and laboratory determinations were within acceptable limits for most constituents and samples. The results of the quality-assurance analyses did not affect any interpretations of ground-water quality data.

In the following sections, data from standard refer ence samples, sample duplicates, blanks, internal sample checks, and checks on field values are discussed. The data are included in the tables of Appendix C.

Standard Reference Samples

Standard reference samples of various concentrations for selected inorganic constituents were inserted as blind samples into the laboratory sample runs at the National Water Quality Laboratory (NWQL). Each standard sam ple was submitted several times to obtain enough data to be statistically meaningful. The results were summarized and are available through computer programs maintained by the U.S. Geological Survey's Branch of Quality Assur ance (BQA). The summary provides the mean concentra tion determined by the NWQL for each standard during a given period, along with the standard deviation of the lab oratory concentrations, coefficient of variation, and num ber of times the standard was submitted and analyzed. These data for standards submitted from April 1 to July 15, 1989, were used to assess the error in the analyti cal accuracy of samples collected and analyzed from 461 Thurston County wells during that period. The standards used in the assessment were only those that enclosed the range of the sample concentrations or, in cases when that was not possible, those that best represented the sample concentrations.

First, the standard deviation of the concentration of a standard reference sample from the true concentration was determined for each standard reference sample using the following equation:

s. = U-MPV (1)

where

s. is the standard deviation of the concentration of the standard reference sample from the true concentration;

s is the standard deviation from the meansconcentration determined by the NWQL;

ug is the mean concentration of the standardreference sample as determined by the NWQL; and

MPV is the most probable value of the standard reference sample. This is an estimate of the true concentration of the standard reference sample based on analyses by as many as 150 independent laboratories.

Then equation 2 was used to determine the coefficient of variation f CV. 1 for the analysis of each standard:

CV. =s. i

MPV(2)

Then the overall coefficient of variation for a particu lar constituent was determined by averaging the squares of the coefficients of variation for all the standards that were in the range of concentrations found in Thurston County. This average was weighted by the number of times each standard was analyzed in the period as follows:

The overall coefficient of variation usually overem phasizes standards at larger concentrations when the con centration ranges over several standards. This is because standards are submitted in approximately equal numbers over a large concentration range, but the concentrations in the ground-water samples are mostly near the smaller end of the range; only a small percentage of samples are near the larger end of the concentration range. In fact, in most cases the median ground-water concentration was smaller than the smallest standard, even though the sample con centration range covered several standards. In extreme cases, such as barium and chromium, the smallest standard concentration was larger than the largest ground-water concentration, so only the smallest standard was used. The consequences of these unequal concentration distribu tions between standards and samples is minimal, though, because the coefficients of variation for the standards do not vary much with concentration.

The overall coefficient of variation was used to esti mate the overall error of analysis of the standard reference samples for the constituent, at the 95-percent confidence level. The following equation was used:

E = I 1.96 xCVol 100 (4)

where

E = overall error of analysis, in percent.

This error is also a representation of the average error in analytical accuracy of the samples from Thurston County and is shown in table B1 for each constituent. It is recognized that this error includes a degree of analytical precision. However, the accuracy and precision are diffi cult to separate in the given data and, in the interest of con servation, the error is considered to be entirely in the accuracy.

The average absolute standard deviation (S0 ) for each constituent, in units based on concentration, is calculated using equation 5 and is shown in table B1.

The estimated errors for the major cations and anions determined in this study are generally reasonable. Qual ity- assurance goals for this study called for a maximum error of 10 percent for cations, anions, and nutrients; all

except potassium, fluoride, and nitrate are in that range. The errors for potassium and nitrate are 20 and 17 percent, respectively, and are probably representative. The larger error of 82 percent for fluoride is a result of the small con centrations that were close to the detection limit. At these low concentrations, acceptable small absolute errors (stan dard deviation) produce large percent errors. For example, an absolute error of 0.2 mg/L is a 20-percent error for a concentration of 1.0 mg/L, but is only a 2-percent error for a concentration of 10 mg/L.

Errors for metals range from 6.1 to 168 percent. In a few instances, the error is well within the goal of 20 percent. However, the generally large percent errors associated with metals usually occur because concentra tions were at or near detection limits for all metals. Even though the percentages themselves are large at these low levels, the absolute errors are acceptable.

Internal surrogate standards were injected into each sample to be analyzed for concentrations of volatile organic compounds. The standards are used to determine percent recoveries, and those that are not detected within a certain percentage of the known concentrations (variable, dependent upon the compound) are identified by the NWQL. No samples were reported to have substandard volatile organic compound recoveries.

There might have been an analytical problem with one of the samples collected in May 1989 from well 17N/01W-02E03. This sample was reported as containing small concentrations of six volatile organic compounds (see table 9 on p. 48). Immediately after this sample was analyzed on the gas chromatograph/mass spectrometer, the instrument malfunctioned. During subsequent testing, the same sample was reanalyzed and no volatile organic com pounds were detected. This second analysis was con ducted, however, several days after the first, and after the suggested sample holding time of 14 days had expired. A second sample was collected in December 1989, and only two of the six compounds detected in May were present in December: 1,2-dibromoethane and 1,2-dichloropropane. Given this confirmation, it was concluded that these two compounds were likely present in the May sample. There fore, the first analysis in May, which identified these two compounds and four others, is probably representative and the data were accepted. From the opposite point of view, the argument for rejecting this analysis and accepting the second May analysis of the original sample (which detected nothing) requires ignoring the violation of the holding time, which could be the real reason nothing was detected.

*At 95-percent confidence level. Computed using equations described in the text and data supplied by the U.S. Geological Survey's Branch of Quality Assurance. Error criterion is 10 percent for cations, anions, silica, dissolved solids, and nutrients. Error criterion is 20 percent for metals and trace elements.

Duplicate Samples

Duplicate pairs of samples were collected for all types of analyses performed. Precision criteria were a 10-percent maximum difference for cations, anions, silica, dissolved solids, and nutrients and a 20-percent maximum difference for trace elements and organic compounds. A difference for each pair was computed as a percentage of the average concentration for the pair. The average differ ence of all pairs and the number of pairs exceeding the dif ference criteria are listed for each constituent in table B2.

For most constituents, the average percent difference is well within the criteria presented above. Exceptions are iron and several trace elements. In almost all cases, the larger percent errors were a result of small absolute differ ences in small concentrations near the detection limit, and are therefore considered acceptable. For iron, a pair of samples from well 19N/01W-32B01 had concentrations of 660 and 840 |ig/L and a pair from 19N/03W-25K01 had concentrations of 68 and 85 |J,g/L, well above the detection limit of 3 |ig/L. This disparity may reflect a sampling or analytical problem, but the overall difference for iron is 16 percent (including these pairs) and the problem is prob ably isolated.

Difference criterion is 10 percent for cations, anions, silica, dissolved solids, and nutrients. Percent-difference criterion is 20 percent for all metals, trace elements, radiochemicals, and organic compounds. No percent-difference criterion was established for bacteria.

2Organic compounds were not detected in any of the duplicate samples, therefore, all differences for these compounds are zero.

Blanks

Blanks of deionized water were processed in the same manner as water samples and sent to the NWQL for analy sis. Although no criteria were set for constituent concen trations in blanks, the significance of any constituent present in a blank is based on how close the constituent concentration is to the detection limit and how small it is compared with the median sample concentration. Also important is the number of times the constituent was detected in blank samples. These data are presented in

table B3 and, when compared with these criteria, concen trations in blanks were considered insignificant for all con stituents except iron, MBAS, dichloromethane, and toluene. Even though iron was detected in 13 blanks, and the maximum concentration was 31 fig/L, the average blank concentration was 6 fig/L. Excluding the one larg est value, the average was 4 fig/L, which is acceptable considering that the median iron concentration was 23 fig/1 in the samples (table Bl). For ground-water MBAS, the largest blank concentration was equal to the median concentration of 0.03 mg/L. However, the con-

157

centrations of concern in the study were 0.04 mg/L or larger, so interpretations are not affected. Blank concen trations of the three volatile compounds were small, but their mere presence is of significance. Dichloromethane and trichlorofluoromethane were not detected in any water

samples. Toluene was detected in one water sample but at a concentration of 0.4 mg/L, twice the largest blank con centration. Toluene may have originated from the labora tory or from the column used to prepare the deionized water.

Internal Sample Checks

Various sums, differences, and ratios based on the principles of aquatic chemistry were computed for each sample. These computations check the consistency between constituent concentrations in a sample, and pro vide a gross check in the accuracy and completeness of the analysis. Two of the most useful computations are the cation-anion balance and the calculated dissolved-solids con centration, which are discussed in the following paragraphs.

The cation-anion balance is calculated as a percent difference, using the following equation:

cations -V anions^ + 100 percent

cations + anons(6)

where

^ cation = the sum of the concentrations of cations, in milliequivalents; and

^T anion = the sum of the concentrations of anions, in milliequivalents.

Ideally, this value is zero, but nonzero values occur when a cation or anion concentration is in error or when an ion present in large concentrations (often a metal) is not analyzed for. The acceptable percent difference varies with the total sum of cations and anions, as shown on figure B1. For the samples collected in Thurston County, the cation-anion balance was good: only 19 of 359 analy ses exceeded the allowable percent difference. Of these, 11 had iron concentrations in excess of 1,000 (ig/L, and the cation sum exceeded the anion sum. For these 11 sam ples, the alkalinity determinations may be too low because the iron could have precipitated as iron carbonate in the untreated alkalinity sample. Of the remaining eight, seven were highly mineralized, with dissolved-solids concentra tions greater than 300 mg/L, and six had chloride concen trations greater than 100 mg/L. It is possible that the large amount of dissolved minerals may contribute to precipita tion reactions in untreated samples, which could have altered the sample chemistry enough to produce an unac ceptable balance. In all 19 analyses, suspect concentra tions were verified by reanalysis. All 19 analyses were kept and used because the indicated error was not likely to be large enough to affect any interpretations of the data. Even the largest difference was only 10.1 percent. Also, when the error could be attributed to a likely constituent, such as the alkalinity, there was no way to determine the correct concentration.

FIGURE B1. Cation and anion percent difference curve.

Calculated solids is the dissolved-solids concentration determined by summing the concentrations of cations, anions, silica, and other major dissolved constituents. This value is theoretically equal to the dissolved-solids concentration determined analytically. Differences usu ally are due to errors in analyses of the various cations or anions (which may be verified by the cation-anion bal ance) or to errors in the analyzed dissolved-solids concen tration.

For this study, the percent difference between the cal culated and analyzed dissolved-solids concentrations was large for many samples. Samples from 106 of 359 wells had differences greater than 10 percent, up to a maximum of 31 percent. Only 139 samples had a difference of 5 percent or less. Furthermore, for 272 samples, the ana lyzed concentrations were less than the calculated concen trations, suggesting a strong bias for one of the determinations.

It was determined that the calculated concentrations of dissolved solids were the more accurate, on the basis of several considerations. First, no widespread problems could be found with the major ion analyses from which the calculated concentrations were determined; as noted previ ously, cation-anion balances were acceptable for most analyses. Secondly, errors in the calculated concentrations are normally errors of omission, usually by not analyzing

159

for a contributing constituent. When that is the case, cal culated concentrations are lower than analyzed concentra tions, the opposite of that observed. Also, when questionable dissolved-solids concentrations were deter mined a second time, commonly the number was substan tially different from the original. This discrepancy is also reflected by an average difference in duplicate pairs of 4.3 percent for analyzed concentrations, but only 0.5 percent for calculated concentrations (table B2). Finally, the error in analysis of the analyzed concentra tions was 9.4 percent (table B1), which is somewhat large, given that all of the dissolved-solids concentrations were much larger than the detection limit.

It was decided, therefore, to use the calculated dis solved-solids concentration for interpretations in the study. This does not imply that the analyzed concentration is a poor number; it is just not as good as the calculated con centration. Subsequent investigations of the problem by personnel of the BQA and the NWQL have determined that a negative bias existed in some dissolved-solids anal yses during the period the samples from this study were analyzed.

Checks on Field Values

The primary controls on the determinations of field values of pH, specific conductance, dissolved oxygen, and temperature are proper instrument calibration and field procedures. However, pH and specific conductance are also determined in the laboratory as standard procedure. Values of laboratory and field specific conductance dif fered by more than 5 percent for only 24 of 359 samples, and exceeded 10 percent for only 10 samples. Field and laboratory pH differed by more than 0.3 units for 86 of 359 samples, but only 31 of these differed by more than 0.5 units; the maximum difference was 1.6 units. Because pH and specific conductance values can change during the time between the field and laboratory determinations, these comparisons must be considered approximations at best, but the good agreement generally serves to confirm the field values.
