1.3 Problem Definition/Background

1.3.1 Background

The Albert City SBA site is located on Orchard Street in the east-central portion of Albert City, Iowa

(see Figure 1, Attachment 1). The site is the location of the former Superior Manufacturing Company

(SMC), which manufactured various products on the property from 1924 to 1967. The primary product

was a line of grease guns. An estimated 17 million grease guns were manufactured by SMC during the

years of operation. Part of the production process required the use of degreasing solvents. Based on

analytical results of soil and ground water at the site, the primary solvent used was TCE (Reference 1).

The site is situated in a mixed commercial/residential area of Albert City (see Figure 2, Attachment

1). The nearest residence is located approximately 70 feet to the west of the former SMC plant property.

The Albert City-Truesdale School with 380 students is located approximately 100 feet northwest of the site

(Reference 1).

The site consists of two areas, including the former SMC plant property and the former SMC waste

storage area (see Figure 2, Attachment 1). The former plant property was used for manufacturing, which

included degreasing. The original plant building on the former SMC plant property has been razed and

the property now consists of a grass-covered open lot with a pole bam on the east portion. The former

SMC waste storage area was an open lot where waste metal shavings produced during the manufacturing

process were stored. The metal shavings were reportedly coated with oil and solvents when placed on the

ground. The former SMC waste storage area is currendy owned by the

three historical/museum buildings are on the property. These buildings include a garage used for storing

maintenance equipment, a museum annex building, and a historic school house (Reference 1).

1.3.2 Previous Investigations and Summary of Findings

Prior to the expanded site inspection (ESI) conducted by the E & E Technical Assistance Team for

$£.0 A- ; . a preliminary assessment (PA) and screening site inspection (SSI) in 1992 by IDNR;

and a site inspection (SI) in 1994 by IDNR. These investigations determined that tetrachloroethane (PCE),

TCE, and degradation products were present in soil and shallow ground water on site. TCE was

detected up to 570,000 milligrams per liter (qg/L) in shallow ground water on the former plant property

(Reference 1).

RO/LKM 1-2 0438ACSFXX/9701044/F

EPA in 1995, previous investigations of the site included a 1991 property assessment by

The ESI field investigation included collection of source (soil on site), soil off site, and ground water

samples. The on-site source soil sampling included collection of screening samples using an Organic

Vapor Analyzer (OVA) and selected laboratory confirmation samples. Based on the OVA results, VOC

contamination is present in an area approximately 100 feet by 200 feet on the former SMC plant property

and an area approximately 70 feet by 150 feet on the former SMC waste storage area. This screening was

not definitive, however, because all areas of VOC contamination were not defined and OVA results are

not contaminant specific. VOC contamination was detected in both areas at depths from 0 to 5 feet below

ground surface (BGS). PCE, TCE, and degradation products, including 1,1-dichloroethene (1,1-DCE),

cis-l,2-DCE, trans-l,2-DCE, and vinyl chloride, were the hazardous substances detected that are

attributable to the site. The highest VOC concentrations detected in on-site soil included cis-l,2-DCE at

40,000 micrograms per kilogram (/xg/kg); trans-l,2-DCE at 240 /xg/kg; PCE at 180 /xg/kg; TCE at 17,000

/xg/kg, and vinyl chloride at 1,400 /xg/kg. Concentrations of vinyl chloride detected in soil on site exceed

the EPA Cancer Risk Screening Concentration of 310 /xg/kg and the EPA Region III Risk-Based

Concentration (RBC) for residential soil of 340 /xg/kg (Reference 1).

The primary aquifer used for drinking water in the area is the glacial drift aquifer consisting of

approximately 400 feet of unconsolidated glacial deposits containing varying amounts of clay, silt, sand,

and gravel. The glacial deposits extend from the surface to approximately 400 feet BGS. All known wells

in the area, including the two Albert City municipal wells, are set in the glacial drift aquifer. Both

municipal wells are located approximately 1,600 feet northwest of the site. The depth to ground water in

the site area ranges from approximately 5.5 to 7 feet BGS. Shallow ground water flow in the immediate

area of the site is to the southeast and is apparendy controlled by a network of drainage tiles in the area.

Ground water flow direction in deeper intervals of the aquifer is unknown (Reference 1). Figure 3,

Attachment 1 illustrates the general geology and hydrogeology of the area.

To characterize shallow ground water on site, ESI samples were collected from temporary

Geoprobe® wells on site and existing monitoring wells at adjacent UST sites. Results indicated that the

shallow ground water underlying the site and the surrounding area has been impacted by VOCs from the

site. The highest concentrations of VOCs detected included 1,2-DCE at 22 /xg/L; cis-l,2-DCE at 23,000

/xg/L; trans-1,2-DCE at 62 /xg/L; PCE at 50 /xg/L; TCE at 23,000 /xg/L, and vinyl chloride at 13 /xg/L.

Concentrations of VOCs in that sample exceeded the respective MCLs for all compounds except trans-1,2-

DCE (Reference I).

RO/LKM 1-3 0438ACSFXX/9701044/F

Municipal wells and the distribution system samples were collected to determine whether the site is

impacting Albert City's water supply. It was found that Albert City municipal well # 1 contained TCE at

2 /xg/L in the primary sample and 1 /xg/L in the duplicate sample. The depth of municipal well # 1 is 190

feet BGS and it is located approximately 1,600 feet northwest of the site (see Figure 1). These concentra­

tions are below the maximum contaminants level (MCL) of 5 /xg/L for TCE. Results of the municipal

water distribution sampling indicated that the sample collected from the Albert City Fire Station tap located

adjacent to the former SMC waste storage area contained TCE at 38 /xg/L and cis-l,2-DCE at 15 /xg/L.

The TCE concentration exceeded the MCL of 5 /xg/L. Water supply lines leading to the fire station are

constructed of PVC and lie under Orchard Street between the former SMC plant property and the former

SMC waste storage area. The water supply lines are buried approximately 5.5 feet BGS and the depth to

ground water is approximately 5 to 6 feet BGS in the area. This suggests that contaminants in the shallow

ground water have apparently degraded the distribution system's PVC piping underlying Orchard Street

and are entering the municipal distribution system (Reference 1).

Private wells outside the city limits were sampled to determine whether the site had impacted the

ground water in the area. TCE at 31 /xg/L and cis-l,2-DCE at 40 /xg/L were detected in the

residence's private well located approximately 0.75 mile^fitheast of the site. The TCE concentration in the.-well exceeded the MCL. The depth of ^^^Cwlll is 40 feet BGS. Due to the distances from

the site and because the ground water gradients in deeperm^rvals of the aquifer are unknown, attribution

of the contaminants in the municipal well and th^^/Well to the site is indefinite. In addition, it is unknown whether other potential sources may exisfnear these wells. An estimated 1,159 people are served

by the Albert City municipal well supply. There are approximately 456 people within a 4-mile radius of the site who obtain drinking watj^^om private wells. There are six other residences with private wells

located in the vicinity of thg$5^fc well (north and northeast of the site) and within 0.75 to 1.25 miles of

the site (Reference 1).

Surface water from the site is drained by storm drains located adjacent to the site. The storm drains

apparently drain both stormwater runoff and shallow ground water away from the area. Surface water

runoff flows through a series of underground drainage tiles for approximately 3.25 miles to the southeast

and enters a perennial stream. Due to the distance to the surface water from the site, no surface water or

sediment samples were collected as part of the ESI. However, during the ESI field work a city employee

reported that while recently excavating near the east side of the site a 10-inch diameter clay drainage pipe

was unearthed and accidentally broken. Inside the pipe black sludge with a strong volatile and petroleum-

like odor was observed. A sheen was also observed on the water in the drainage pipe (Reference 1).

RO/LKM 1-4 0438ACSFXX/9701044/F

Surface soil samples were collected during the ESI on and off site to establish contaminant concentra­

tions and determine whether migration off site has occurred. It was found that VOCs are present on site

at both the former SMC plant property and the former SMC waste storage area. In addition, surface soil

samples collected at the nearest residence and at the background location contained cis-l,2-DCE at 12

jig/kg and 22 fig/kg, respectively. Vinyl chloride was detected in soil on the former SMC waste storage

area at concentrations exceeding the CR and RBC. Both site areas are readily accessible to the public.

The Albert City-Truesdale School with a student population of 380 is located approximately 100 feet to the

west of the site. Students from the school occasionally visit the historical buildings and museum on the

former SMC waste storage area. Approximately 830 people live within 1 mile of the site and 1,153 people

live within 4 miles of the site (Reference 1).

A removal assessment was conducted by START at the Albert City SBA site in Albert City, Iowa

from August 12 to 16, 1996. Sampling included wells, the municipal distribution system, the storm sewer,

and ambient air on site. Sampling of ground water included active private drinking water wells outside

Albert City, the two Albert City municipal wells, and private wells (active and inactive) in Albert City.

This ground water sampling was conducted because the ground water on site is known to be significantly

contaminated with TCE and its transformation products and previous ESI results indicated that a municipal

well and a private well located 0.75 miles northeast of the site contained TCE contamination. Additional

distribution system sampling was conducted because previous ESI results indicated that TCE was present

in a system sample collected at the fire station which is adjacent to the site. Sample results from the well

sampling and the distribution system sampling indicated no VOCs were present above detection limits,

including the samples collected at locations that had VOC contamination during the ESI. It was concluded

that this variance in sample results may be due to temporal and/or spatial changes in ground water

conditions and that additional periodic sampling is necessary to verify and monitor contaminant

concentrations (Reference 2).

Storm sewer water and sediment sample results indicate that VOCs attributable to the site are entering

the storm sewer to the east and west of the site. Sampling of the storm sewer outfall located 3.25 miles

south of the site indicated that no VOCs were present above detection limits. The storm sewer piping is

constructed of perforated piping that serves two functions: draining storm water and shallow ground water.

Because the piping is perforated, it was concluded that it may act as a conduit for water drainage that is

potentially facilitating the spread of contaminants through the system and to the shallow ground water

adjacent to the piping (Reference 2).

RO/LKM 1-5 0438ACSFXX/9701044/F

Air samples collected inside buildings (museum annex and historic school house) built or

reconstructed on top of the former SMC waste storage area indicated the presence of site-related VOCs,

including cis-l,2-DCE and TCE, in the ambient air. Concentrations of TCE in both buildings significantly

exceeded the Region III RBC for TCE in ambient air. These contaminants were also detected in surface

and subsurface soil samples previously collected around the buildings. Therefore, it was concluded that

site-related VOCs from the former SMC waste storage area are apparently being released to the ambient

air and are impacting the air inside two buildings on site. The buildings are museum buildings that are open

one day per week from Memorial Day through Labor Day and by appointment throughout the year

(Reference 2).

Currently, EPA is conducting periodic sampling of the municipal wells, selected private wells, sewer

sampling, and air sampling at the site. The last sampling event was conducted in December 1996. Not

all sample results have been received from the December sampling. Partial results from the storm sewer

sampling indicate that TCE and DCE are present in the storm sewer approximately 2,200 feet southeast

of the site. This indicates that contamination is migrating from the site in the storm sewer and because the

piping is perforated it may be releasing contaminants to the adjacent shallow ground water along the piping.

Because the site is located adjacent to a residential area and a school, residents and school children

can be exposed to contaminated soil on site via direct contact or inhalation. In addition, ground water at

the site is contaminated with VOCs and the extent of contamination has not been delineated. Albert City

acquires municipal water from two wells located 1,600 feet from the site and residents outside of the town

have private wells to supply their drinking water; therefore, if contaminants migrate in the ground water

to these drinking water sources residents could also be exposed to contaminants via ingestion.

1.4 Project/Task Description

The objectives of this project are to determine the extent and concentration levels of VOC-

contaminated soil on site and to determine whether levels exceed health-based action levels; determine the

extent and concentrations of ground water contamination on site and whether they exceed health-based

action levels; approximate the extent of soil vapor or ground water contamination off site to determine

whether it is migrating toward a drinking water source; and conduct an additional round of air, drinking

water, and storm sewer sampling at locations previously sampled or suspected of being impacted for

monitoring purposes. The resulting data will be used to determine whether the site poses a threat to

residents and to recommend further removal or response action.

RO/LKM 1-6 0438ACSFXX/9701044/F

Selected site-specific action levels have not been developed by EPA Region VII for the site. Table

1 presents general guideline values for action levels for the primary contaminants of concern based on the

Region VII Screening Table. The EPA Region VII analytical SOPs listed in Section 2.4 will provide

adequate detection limits for the soil, air, and water samples.

The field work will take 14 to 18 days to complete and will be initiated within 3 weeks of EPA’s

approval of this project plan.

1.5 Quality Objectives and Criteria for Measurement Data

The project data quality objective is to provide valid data of known and documented quality for the

area sampled to determine the area impacted by VOC contamination for comparison to the associated

action levels. The data quality indicators to be measured are identified below.

RO/LKM 1-7 0438ACSFXX/9701044/F

The goals for analytical precision and accuracy are described in Region VII EPA/ENSV SOP

3122.2C and will be applicable to this project. Representativeness will be addressed by collecting the

samples as described in this document. Comparability will be addressed by collecting, analyzing, and

reporting the data as described in this document. A completeness goal of 100 percent is required for this

project. Valid data are required to allow an appropriate decision regarding further action at this site.

1.6 Special Training Requirements/Certification

The only required formal training of site personnel will be the completion of a basic 40-hour health

and safety training course (Hazardous Waste Operations and Emergency Response [HAZWOPER]) and

annual refreshers of the same. Familiarization with sampling equipment and procedures will also be

necessary for the START sampling team.

1.7 Documentation and Records

START personnel will maintain a field logbook to record all pertinent activities associated with the

sampling event. Sample documentation will follow Region VII EPA/ENSV SOP 2130.3B: “Identification,

Documentation and Tracking of Samples”. Information pertaining to samples (i.e. sample dates, times,

matrix, location) collected during this project will be recorded on field sheets provided by Region VII EPA

Laboratory personnel (generated by the Labor and Sample Tracking System [LAST]).

Analytical information will be handled according to Region VII EPA/ENSV SOPs 2410: “LABO

Branch Data Management Procedures” and 2410.10A: “Analytical Data Submission Packages”.

RO/LKM 1-8 0438ACSFXX/9701044/F

2.0 MEASUREMENT/DATA ACQUISITION

2.1 Sampling Process Design and Methods Requirements

The sampling approach will be divided into six tasks: 1) Soil sampling on site; 2) Soil gas survey;

3) Monitoring well installation, development, sampling, and aquifer testing; 4) Drinking water sampling;

5) Air sampling; 6) Storm sewer sampling. Each of these tasks is discussed in detail in subsections 2.1.1

through 2.1.6.

2.1.1 Soil Sampling On Site

To delineate the areal and vertical extent of VOC-contaminated soil on site in the vadose zone and

to establish contaminant concentration levels, soil samples will be collected and then screened in the field

using a gas chromatograph (GC). Approximately 10% of the samples will be submitted for laboratory

analysis to confirm screening results. Samples will be collected from the former SMC plant property and

at the former SMC waste storage area. Properties adjacent to the storage area will also be sampled because

information indicates waste may also have been stored on those properties.

Initially, a grid with 30-foot spacing will be set up over the properties. Figure 4 illustrates the grid.

Samples will be collected at the grid centers from depth intervals of 0 to 2 feet and 3 to 5 feet BGS. A

maximum depth of 5 feet BGS will be sufficient to characterize the vadose zone soil contamination because

depth to ground water is approximately 5.5 to 6 feet BGS. Past experience at similar sites indicates that

a 30-foot grid spacing and the depth interval sampling will be sufficient to delineate the VOC contamination

for removal considerations. Grid spacing may be adjusted to a smaller spacing (e.g. 15 foot) in selected

locations depending on the results and need to more precisely define areas. It is estimated that

approximately 120 to 140 screening samples will be collected and 12 to 14 samples will be submitted for

laboratory confirmation.

Soil sampling procedures with a Geoprobe sampling unit will follow the Region VII SOP 2230.7A:

“Geoprobe Operations”. A sampling tube (2-foot length and 1-inch inside diameter with a disposable

inner acetate soil sampling sleeve) attached to the probe rod will be advanced through the soil to the

starting sampling depth. A 2-foot composite soil sample will be collected from 0 to 2 feet BGS and 3 to

5 feet BGS. Sample containers (40-mL VOA vials) will be filled immediately with aliquots collected along

the entire length of the sample core. In addition, the lithology of each sample will be logged. All soil

RO/LKM 2-1 0438ACSFXX/9701044/F

sampling will follow Region VII SOP 2230.3B: “ Sampling Soils for Determination of Volatile Organic

Compounds” and Region VII SOP 2231.12A: ERT tt 2012; “Soil Sampling”.

The samples will be screened on site with a GC, which will provide rapid real-time, semiquantifiable

results of the target VOCs. The GC will be calibrated to detect 1,2-DCE, TCE, and vinyl chloride, which

are the contaminants previously detected at the highest concentrations in the soil and ground water at the

site. The operation of the GC will follow Region VII SOP 2231.109A: ERT #2109; “Photovac GC

Analysis for Air, Soil Gas, Water & Soil”. Analytical documentation will consist of a sample printout with

the sample number or identifier, date, time, TDD number, and chromatographic results. A logbook will

be kept with entries pertaining to calibration, instrument settings, sample locations, and analytical results.

All confirmation samples will be submitted to the Region VII EPA Laboratory for VOC analyses. Table

2, on page 2-9, provides a summary of the proposed samples.

2.1.2 Soil Gas Survey

To delineate the extent of soil vapor contamination in the vadose zone in areas off site, a soil gas

survey will be conducted. A grid with an approximately 150 foot spacing will be set up surrounding the

site area in all directions. Grid spacing ranging from 100 feet to 300 feet has been used for soil gas

surveys at similar sites by START and has been adequate to delineate soil vapor contamination. A vertical

profile will be performed by collecting soil gas samples at various depths at a location near the site to

determine the optimum sample depth. Soil gas samples will be analyzed in the field using a GC. Once

the sample depth has been established, samples will be collected at the grid nodes. Initially, samples will

be collected at or near the site and then subsequent samples will be collected from the grid in areas where

soil vapor contamination is present and continue until the boundaries of soil vapor contamination are

defined. The specific locations and number of samples will be determined in the field, based on field­

screening results. It is estimated a maximum of 35 soil gas samples will be collected. The approximate

locations of the grid nodes are illustrated on Figure 5. It is anticipated that locations will be adjusted based

on field conditions (i.e. access to property, buried utilities, buildings).

The soil type underlying the area consists of clayey glacial till, which may be dense and contain little

pore space for soil gas. If the soil pore space is insufficient, collection of adequate volume for soil gas

sampling may not be possible. If this occurs, soil samples from the vadose zone will be collected at the

grid locations in the manner described previously and screened for target VOCs.

RO/LKM 2-2 0438ACSFXX/9701044/F

Laboratory confirmation of the on-site analyses will include submittal of samples to the EPA Region

VII Laboratory. Confirmation samples for laboratory analysis will be collected and submitted for

approximately 10 percent (3 samples) of the soil gas or soil headspace screening samples. These sample

locations will be selected based on screening results, with a goal of confirming a range of concentrations.

Soil gas or soil sampling procedures, using the Geoprobe sampling unit will follow the Region VII

SOP 2230.7A: “Geoprobe Operations”. The techniques for collection of soil gas and soil samples are

briefly described below.

Soil gas samples will be collected by pushing successive 3-foot sections of (1-inch outside diameter,

0.75-inch inside diameter) steel rods with a disposable point into the subsurface using a hydraulically driven

Geoprobe. When the desired depth is attained, the rod sections will be raised approximately 6 inches.

Polyethylene tubing will be inserted inside the rod, threaded downward, and secured to the bottom section

with a hollow nipple attachment. The soil gas from the bottom of the rod will then be extracted through

the tubing using a vacuum pump and collected in a glass bulb for field screening or a Summa canister for

laboratory analysis. Summa canister samples will be collected in accordance with Region VII SOP

2231.704A : ERT#1704; Summa Canister Sampling.

Soil samples will be collected using a sampling tube (2-foot length and 1 inch inside diameter with

a disposable inner acetate soil sampling sleeve) attached to the probe rod. The tube will be advanced

through the soil to the starting sampling depth. A 2-foot composite soil sample will be collected. Sample

containers (40-mL VO A vials) will be filled immediately with aliquots collected along the entire length of

the sample core. All soil sampling will follow Region VII SOP 2230.3B: “ Sampling Soils for

Determination of Volatile Organic Compounds” and Region VII SOP 2231.12A: ERT # 2012; “Soil

Sampling”.

The.soil gas or soil samples will be screened on site with a GC providing rapid real-time,

semiquantifiable results of the target VOCs. The GC will be calibrated to detect 1,2-DCE, TCE, and vinyl

chloride, which are the contaminants previously detected at the highest concentrations in the soil and

ground water at the site. The operation of the GC will follow Region VII SOP 2231.109A: ERT #2109;

“Photovac GC Analysis for Air, Soil Gas, Water & Soil”. Analytical documentation will consist of a

sample printout with the sample number or identifier, date, time, TDD number, and chromatographic

results. A logbook will be kept with entries pertaining to calibration, instrument settings, sample

locations, and analytical results. All confirmation samples will be submitted to the Region VII EPA

Laboratory for VOC analyses. Table 2, on page 2-9, provides a summary of the proposed samples.

RO/LKM 2-3 0438ACSFXX/9701044/F

2.1.3 Monitoring Well Installation, Development, Sampling, and Aquifer Testing

As previously described, the static water level at the site is between 5 to 7 feet BGS and is within

unconsolidated glacial drift deposits that are approximately 400 feet thick. This aquifer is used throughout

the site area for municipal and private water supplies. No monitoring wells have been installed on the site

to determine the contaminants and concentration levels; however, monitoring wells do exist in the site

vicinity at three UST sites. Therefore, six (6) shallow (—15 to 20 feet BGS) monitoring wells will be

installed and sampled on the former SMC properties to establish contaminant concentrations and six (6)

existing monitoring wells will be sampled at the UST sites to determine whether contaminants attributable

to the site are migrating off site in the shallow portion of the aquifer. To evaluate vertical migration of

contaminants and gradients single deep wells (~ 30 to 35 feet BGS) will be collocated at 3 of the shallow

well locations. In addition, aquifer testing will be conducted to establish aquifer properties for evaluating

flow rates, gradients, contaminant transport, and to assess the feasibility of removal or remedial

alternatives.

Three shallow monitoring wells will be installed on the former SMC plant property. Two shallow

monitoring wells will be installed on the former SMC waste storage area. One shallow well will serve as

a background well and will be located north of the properties. One deep well will be located on the former

SMC waste storage area and two will be located on the former SMC plant property. The proposed

approximate well locations are illustrated on Figure 2. The existing UST monitoring wells that will be

sampled include three at the Buena Vista County UST site, two at REDACT?^ -■ UST site,

and one at ReDAC site. figure 2 also illustrates the locations of the UST wells.

2.1.3.1 Monitoring Well Installation

The nine unconsolidated monitoring well boreholes will be drilled with 4.25-inch inside

diameter (I.D.) hollow-stem augers. For the shallow wells the hollow stem augers will be advanced to

approximately 8 feet beneath the top of the static water table, where a 2-inch I.D. stainless steel (type 304)

monitoring well will be constructed. It will necessary to use stainless steel rather than PVC because TCE,

which will degrade PVC, is known to be present in the ground water at high concentrations (up to 570,000

ug/L). Continuous soil cores will be collected from each borehole using a 5-foot-long wire line core

barrel. The lithology of each soil core will be described and recorded by the on-site geologist. The hollow

stem augers will be used as a temporary casing for the construction of the monitoring wells, preventing the

collapse of natural formation materials around the well screen and casing. The deep wells will be drilled

and constructed using the same procedures.

RO/LKM 2-4 0438ACSFXX/9701044/F

Figure 6 illustrates the proposed monitoring well construction details. The well casing will be

constructed of 2-inch I.D. 304 stainless steel with flush-threaded joints. No solvents or glues will be used

as joining compounds. The bottom of the casing will terminate with 10 feet of stainless steel screen. The

shallow wells will have 8 feet of screen below and 2 feet of screen above the water table, to allow for

seasonal water table fluctuations. Based on geologic information, it is anticipated formation materials in

the screened interval will be clay till with minor amounts of silt, sand, and gravel. Therefore, the screen

will be factory slotted with a slot size of 0.006 inches. The annular space between the well screen and the

borehole wall will be backfilled with 40-140 mesh clean silica sand. The sand will be rounded to

subrounded and placed to a level at least one and up to 2 feet above the top of screen. A 2-foot thick

bentonite seal will be placed above the sand pack. The remainder of the annular space will be backfilled

with a portland cement bentonite (5% bentonite by weight) grout to within 2 feet of ground surface. All

backfilled materials will be placed in 5-foot lifts prior to retraction of the augers with a minimum of two

feet of materials remaining in the augers at all times. Each lift will be tagged for depth prior to retraction

of the augers. The well installation will be completed with a concrete plug in the upper 2 feet of the

borehole in which a flush-mounted steel protective outer casing with locking cap will be installed. A 3-

by 3-foot sloping concrete pad 4 inches thick will be constructed at ground surface to divert any surface

water away for the well head.

2.1.3.2 Monitoring Well Borehole Soil Sampling

Each of the nine monitoring wells will be drilled using 4.25-inch internal diameter (ID) augers

and continuous soil samplers. The unconsolidated materials will be continuously sampled and logged to

obtain lithology. Each continuous sample will be field screened in the field laboratory using procedures

described in section 2.1.1. One screening sample will be collected for each 5-foot interval (e.g. 0'-5', 5'-

10', 10'-15’ etc.) at each of the nine monitoring well locations resulting in up to 30 soil screening samples.

Approximately 10 percent (3 samples) of the screening samples will be submitted for laboratory

confirmation. Samples will be collected in accordance with Region VII EPA SOP #2230.3B “Sampling

Soils for Determination of Volatile Organic Compounds”. Each laboratory sample will be collected into

two 40-mL vials and cooled to 4°Celsius. Soil confirmation samples will be submitted to the Region VII

EPA Laboratory for VOCs analysis.

In addition, six soil samples will be collected from three monitoring well locations (one on the

former SMC waste storage area and two on the former SMC plant property) and submitted for grain size,

moisture content, and total organic carbon (TOC) analyses. The specific locations will be determined in

RO/LKM 2-5 0438ACSFXX/9701044/F

the field. Two samples will be collected at each location, including one sample from the vadose zone and

one sample from the screened portion of the aquifer. Results of these analyses will be used when

evaluating the feasibility of alternative remedies. These analyses will be performed by a laboratory under

subcontract to START. Table 2, on page 2-9, provides a summary of the proposed samples.

2.1.3.3 Well Development

Newly completed monitoring wells will not be developed for at least 24 hours after well

completion. Each well will be developed by surging and pumping or bailing until the well is visibly free

of sediment. In addition, the pH, temperature, and specific conductance will be monitored during the

development. Stabilization will be considered to have been achieved when the variation between three

consecutive readings is no greater than 10 percent. No acids, dispersing agents, or explosives will be used

to enhance well development. No water or other liquid will be introduced into the well other than

formation water from that well.

2.1.3.4 Monitoring Well Sampling

After stabilization of the water levels in each well, an electronic water level indicator will be

used to measure the depth to ground water. Before a ground water sample is collected, a minimum of three

volumes of the standing water column will be purged. Ground water temperature, pH , and conductivity

will be measured after each volume has been purged to ensure that stagnant water in the well is removed.

Analytical samples will be collected from each well using a dedicated bailer. The samples will be poured

direcdy from the bailer into the appropriate sample container.

A total of 15 ground water samples for VOCs will be collected from the nine newly installed

monitoring wells and the six existing UST monitoring wells (Table 2). The ground water samples will be

collected in accordance with Region VII SOP 2334.15A: “Ground Water Sample Collection”. The ground

water samples will be collected in four 40-mL VOA vials, preserved with hydrochloric acid to a pH less

than 2, and cooled to 4°Celsius. All monitoring well samples will be submitted to the Region VII EPA

Laboratory for lower detection limit (LDL) VOC analyses. In addition, three ground water samples will

be collected from three monitoring wells (one on the former SMC waste storage area and two on the

former SMC plant property) and submitted for total dissolved solids, hardness, pH, and sulfates analyses.

The specific locations will be determined in the field. Results of these analyses will be used when

evaluating the feasibility of alternative remedies. Table 2, on page 2-9, provides a summary of the

proposed samples.

RO/LKM 2-6 0438ACSFXX/9701044/F

2.1.3.5 Aquifer Testing

A slug test will be performed on selected wells including at least three (2 shallow and one deep)

on the former SMC plant property and two (one shallow and one deep) on the former SMC waste storage

area. The slug test will be performed by suddenly removing a slug (segment of solid PVC pipe) of known

volume and observing the recovery of the water surface to its original level. The slug will be removed

from the well as quickly as possible after measurements indicate that the water level has stabilized.

Depth-time measurements will commence immediately following removal of the slug (t=o) and will

continue until the water level returns to equilibrium conditions. The hydraulic conductivity will then be

estimated according to the following calculation:

K = r2 In (L/R)2 LT0

where:

K = hydraulic conductivity (ft/sec)

r = casing radius (ft)

L = length of open screen (or borehole) (ft)

R = filter pack (borehole) radius (ft)

T0= basic time lag (sec), where value of t on semilogarithmic plot of (H-h)/(H-H0) vs. t, when(H-h)/(H-H0) = 0.37.

H = initial water level prior to removal of slug

Hq= water level at t = 0

h = recorded water levels at t>0

The monitoring wells will be surveyed for elevation and the water levels will be measured to the

nearest 0.01 foot to determine precise ground water flow directions.

2.1.4 Drinking Water Sampling

As part of the continuing monitoring for the site, drinking water samples will be collected from wells

and the municipal distribution system at locations known or suspected to be impacted by the site. Samples

will be collected from five private wells, the two municipal wells, and at four distribution points. The

RO/LKM 2-7 0438ACSFXX/9701044/F

locations of the private wells and the municipal wells are illustrated on Figure 1. Three of the distribution

samples will be collected from the Albert City School and one from the Albert City Fire Department (see

Figure 7).

The drinking water samples will be collected in accordance with Region VII SOP 2334.10A:

“Drinking Water Sample Collection”. The samples will be collected in four 40-mL VOA vials, preserved

with hydrochloric acid to a pH less than 2, and cooled to 4°Celsius. All drinking water samples will be

submitted to the Region VII EPA Laboratory for LDL VOC analyses. Table 2, on page 2-9, provides a

summary of the proposed samples.

2.1.5 Air Sampling

Previous air samples collected in buildings on or adjacent to the former SMC storage area contained

elevated concentrations of TCE and cis-l,2-DCE. To determine whether other buildings near the site are

being impacted, three additional air samples will be conducted. Samples will be collected inside the two

nearest residences on Orchard Street west of the site and from the Albert City-Truesdale School. Figure

7 illustrates the proposed air sample locations.

Air sampling will be conducted with Summa canisters over a 10-hour sampling period, which will

run from approximately 0800 hours to 1800 hours. The evacuated canisters will be attached to a vacuum

pump to obtain a pressurized sample (filled to approximately 7 pounds-per-square-inch [psi]) to allow for

lower detection limits (as compared to subatmospheric pressure sampling). The air samples will be

collected in accordance with Region VII SOP 2231.704A: ERT #1704; “Summa Canister Sampling”.

Prior to sampling, the canisters will be cleaned according to Region VII SOP 2231.703A: ERT #1703;

“Summa Canister Cleaning”. Air samples will be submitted to the Region VII Laboratory for VOC

analysis. Table 2 summarizes the proposed samples.

2.1.6 Storm Sewer Sampling

As part of the continuing monitoring at the site, storm sewer water samples will be collected from

locations known to be impacted by the site. The storm sewers in Albert City are constructed of perforated

piping and serve two purposes: collection and draining storm water runoff; and draining of shallow ground

water. Samples previously collected from the storm sewer have contained TCE, 1,2-DCE, and vinyl

chloride. Three storm sewer water samples will be collected: one from the access on the southeast comer

of the former SMC plant property; one from the access located approximately 2,200 feet southeast of the

RO/LKM 2-8 0438ACSFXX/9701044/F

site; and one from the storm sewer outfall located approximately 3.25 miles south-southeast of the site.

Figures 2 and 8 illustrate the proposed sample locations.

The storm sewer water samples will be collected in accordance with Region VII SOP 2334.7A:

“Surface Water Sample Collection”. The samples will be collected in four 40-mL VOA vials, preserved

with hydrochloric acid to a pH less than 2, and cooled to 4°Celsius. All storm sewer water samples will

be submitted to the Region VII EPA Laboratory for low detection limit (LDL) VOC analyses. Table 2

provides a summary of the proposed samples.
