DRAFT Levine-Fricke-Recon ? published map (1995) of groundwater elevations prepared by SJC FCWCD is presented in Figure 7. Groundwater elevation data collected from Chevron and Exxon monitoring wells, located in the vicinity of Lincoln Center, are presented in Appendix C. These data f were compared to groundwater elevations collected from existing Site monitoring wells ! (LFR 1996b, 1997a). Publicly available analytical results of groundwater samples collected from domestic, 1 municipal supply, and selected monitoring wells and analyzed for volatile organic compounds (VOCs), including the Hazardous Substances, are presented in Table 5. j These data were compiled from the following sources: 1 A table listing analytical results of samples collected from domestic wells located in the Study Area, which was obtained from records filed at the Project Depository located at the Margaret Troke Branch of the Stockton Public Library. The well survey was conducted in the spring of 1987. The source of this survey has not been identified. LFR contacted the RWQCB and SJC PHS/EHD to identify the source and neither agency was familiar with this historical survey. • A 1988 well survey prepared by LH in which municipal and domestic wells were sampled and analyzed for VOCs (LH 1988). The locations of the domestic wells that were sampled and reported in this reference match the locations of the domestic wells listed in the 1987 survey. Tables summarizing the analytical results of groundwater samples collected from wells LVMD #1, LVMD #2, and LVMD #6 from 1987 to 1990, prepared by Kennedy/Jenks Consultants (KJC) (Nakano 1992). Analytical results of groundwater samples collected from wells COS #4, COS #5 COS #11, and COS #12 from 1991 to 1993, provided by the City of Stockton Department of Municipal Utilities. Analytical results of groundwater samples collected from monitoring wells installed at the Chevron service station and analyzed for VOCs (Gettler-Ryan, Inc. 1995). 6 • Analytical results of groundwater samples collected from monitoring wells installed at the Exxon service station, and analyzed for VOCs (WEGE 1993, 1994, 1995). The RDFS Work Plan (LFR 1996a). Analytical results of groundwater samples collected from existing Site monitoring wells (LFR 1996b, 1997a). An evaluation of the groundwater analytical results are described in Section 3.3 of this report. Recommendations for sampling selected wells for subsequent laboratory analysis are presented in Section 4 of this report. 4111WELL.AW AW Page 5
