DATA ON CHLOROFLUOROCARBONS (CC13F and CCl^ AS DATINGTOOLS AND HYDROLOGIC TRACERS IN SHALLOW GROUND
WATER OF THE DELMARVA PENINSULA
L.N. Plummer, S.A. Dunkle, and Eurybiades Busenberg
ABSTRACT
Data on concentrations of two chlorofluorocarbons (CFC's; CC13F and CC12F2), tritium, and oxygen-18 and deuterium stable-isotope composition; pH; water temperature; dissolved oxygen (DO); and specific conductance are reported for ground water from 109 shallow wells in sediments of the Delaware-Maryland-Virginia (Delmarva) Peninsula of the mid-Atlantic Coastal Plain. The shallow piezometers were sampled during May 1989 - December 1992, and are part of a network of monitoring wells established by the U.S. Geological Survey's National Water Quality Assessment Program. pH, DO concentration, specific conductance, and temperature were measured at the sampling site. Water samples collected for CFC analysis were flame-sealed into 62 milliliter borosilicate-glass ampules in the field and returned to the laboratory for analysis. The data on the chemical, isotopic, and chlorofluorocarbon composition of Delmarva ground water are tabulated in two appendixes. Recharge ages are assigned to each water sample and tabulated for each well sampled. The data are being used to evaluate the reliability and utility of CFC's as age-dating tools for shallow ground water.
INTRODUCTION
Chlorofluorocarbons are stable synthetic compounds that have been used in age-dating and tracing ground water (Randall and Schultz, 1976; Thompson and Hayes, 1979; Busenberg and Plummer, 1991, p. 542-547; Busenberg and Plummer, 1992; Busenberg and others, 1993; Plummer and others, 1993). The introduction of a sampling procedure for the collection and storage of water samples in borosilicate-glass ampules without contact with air (Busenberg and Plummer, 1991; Busenberg and Plummer, 1992) has facilitated age-dating of ground water using CFC's in a variety of environments. Busenberg and others (1993) evaluate the CFC age-dating method for ground water and unsaturated-zone air in the Snake River Plain Aquifer at the Idaho National Engineering Laboratory, Idaho. Plummer and others (1993) summarize the CFC age-dating method, evaluate the effects of hydrodynamic dispersion, and compare CFC age-dating to dating methods incorporating other environmental tracers. Dunkle and others (1993) apply CFC age-dating to shallow ground water of the Delmarva Peninsula, mid-Atlantic Coastal Plain.
This report presents data on concentrations of two chlorofluorocarbons (CFC's; CC12F, hereafter referred to as CFC-11, and CC12F2 , hereafter referred to as CFC-12) and other chemical, isotopic and hydrologic data for ground water collected from shallow coastal plain sands on the Delaware-Maryland-Virginia (Delmarva) Peninsula of the mid-Atlantic Coastal Plain. The data are discussed and interpreted in a companion report (Dunkle and others,
1993). The data were collected during May 1989 - December 1992, as part of a study being conducted by the U.S. Geological Survey to investigate applications of CFC's as tools for age-dating ground water.
DATA ON CHLOROFLUOROCARBON CONCENTRATIONS
The wells sampled were selected from a monitoring network established by the U.S. Geological Survey as part of its National Water Quality Assessment (NAWQA) Program. With few exceptions (see Dunkle and others, 1993), the wells are 5.08-cm (2-inch inside diameter (i.d.)) polyvinyl chloride (PVC) piezometers with 0.91-m (3-ft-long) screened intervals at the bottom. The location of wells on regional transects and the location of local-scale networks sampled in this study are shown in figure 1. Further details of well construction are given in Dunkle and others (1993).
Appendix A includes the assigned well number, name, local identifier, latitude, and longitude; the date of sampling; the formation sampled; a generalized classification of the hydrogeologic environment (as either recharge zone, discharge zone, confined aquifer, or location in an area of low hydraulic gradient) (see Dunkle and others, 1993, for criteria used to classify hydrogeologic environments); altitude of the land surface; depth to top and bottom of the screened interval; depth to water; time when well purging began; concentrations of tritium (3H, in tritium units, TU's, and reported for the date of sampling); stable isotope compositions of O and H (in per mil relative to Vienna Standard Mean Ocean Water (VSMOW) and compositions normalized on scales such that the O and H isotopic compositions of Standard Light Antartic Precipitation (SLAP) are -55.5 (d 18O) and -428 (dD) per mil, respectively (Coplen, 1988)); purging times corresponding to field measurements of water temperature, pH, dissolved oxygen concentration (DO, in milligrams per liter); and specific conductance (in microsiemens per centimeter (uS/cm) at 25 degrees Celsius).
The duration of well purging was at least that required to remove three well volumes prior to sampling (typically 20 to 40 minutes). Water samples were collected by means of a helical-rotor submersible pump (Keck1) with a 1.3-cm (0.5-inch i.d.) Teflon discharge line at pumping rates of approximately 20 to 80 cm3/s. Typically the wells were purged with the pump positioned 1 to 2 m above the screened interval. Stability in the field-recorded properties pH, temperature, DO, and specific conductance was also used to determine purging times prior to the start of CFC sampling. After purging was completed, the pump was lowered into the screened interval for sampling.
A total of 109 wells were sampled for CFC's (Appendix B). Multiple samples were collected for CFC analysis (typically six samples) during each well sampling. Many of the wells were sampled in the fall of 1991 and in the spring of 1992. Some wells were sampled on four separate occasions. Each water sample was flame-sealed into a borosilicate-glass ampule

and returned to the U.S. Geological Survey Chlorofluorocarbon Laboratory in Reston, Virginia, for analysis. CFC data for selected surface waters on Delmarva are included in Appendix B (samples 110-116).
Appendix B lists measured concentrations of CFC-11 and CFC-12 in each sealed ampule, in picograms per kilogram of solution (pg/kg), for each sampling time at each well. Busenberg and Plummer (1992) describe the sampling and analytical procedures. Appendix B also includes the calculated atmospheric CFC concentration that would exist in equilibrium with the analyzed concentration in the ground water at the recharge temperature. The recharge temperatures used to calculate the equilibrium partial pressures of CFC's were 9°C for wells 1-97 and 14°C for wells 98-109 (Dunkle and others, 1993). The water temperatures used for surface water samples 110 to 116 are given in Dunkle and others (1993) where additional information on the method of calculation of recharge age also is given. Appendix B also gives the modeled CFC-based recharge dates resolved to the nearest 0.5 years for CFC-11 and CFC-12 for each water sample (ampule) and a summary for CFC-11 and CFC-12 analyses of all samples for the sampling date; the appendix lists the average Julian recharge date, the average water age, and the standard deviation of water age, in years, as reported in Dunkle and others (1993).
The CFC-based ages are referenced to the National Oceanographic and Atmospheric Administration (NOAA) atmospheric air scale for air sampled at Niwot Ridge, Colorado (Elkins and others 1993). The atmospheric concentrations of CFC's used to calculate water ages are given in Busenberg and others (1993) and Dunkle and others (1993). The reader is referred to Hamilton, Shedlock and Phillips (1989), Hamilton and Shedlock (1992), and Shedlock and others (1993) for information on the Delmarva Peninsula study area, and to Dunkle and others (1993) for discussion of the results of the CFC dating of Delmarva ground water.
Dashed lines in Appendix B indicate that the concentrations of CFC-11 or CFC-12 were below the detection limit of 1 pg/kg, or that the CFC-11 or CFC-12 peak on the chromatogram could not be separated from another peak such as that of N2O. The assigned age is determined for the remaining samples according to procedures given in Busenberg and Plummer (1992) and Dunkle and others (1993). The wells sampled in 1989 show extreme variations because of the infancy of the dating technique at the time they were collected. Samples were also contaminated with CFC-11 that was introduced from the Tygon tubing used in the sampling equipment at the time. For these wells, the analyses were not averaged, but the oldest age obtained for any sample was chosen as the assigned age; this oldest age represents a minimum age. Some ages appear to be more uncertain compared to other ages of water samples from a particular well; however, there is no obvious basis to discard these uncertain ages, which, although retained in the data base, were not included in obtaining the averaged assigned ages (Appendix B). Dunkle and others (1993) discuss the criteria used in assigning recharge ages for the Delmarva waters.
