1.0 INTRODUCTION chis report describes field activities that were performed during the third quarter of 2003 on behalf of Mr and Mrs James Fisk, owners of the property located at 8125 S E1 Dorado Street in French Camp, California (Figure 1) Mr and Mrs Fisk operate J&L Market and Service at this address, and have been designated by the State Water Resources Control Board UST Cleanup Fund as the Responsible Party (RP) for petroleum contamination related to underground fuel tanks at that facility Contamination was discovered during the removal of three single-walled UST s and related piping in November 1995, and extensive interim remediation in the form of soil excavation then took place Upgradient Environmental Consultants (Upgradient Enviionmental) conducted further investigation in November 2001 to determine whether groundwater was impacted by the petroleum release, and submitted a Preliminary Investigation and Evaluation Report (PIER) in December 2001 Because evidence of groundwater contamination was obtained, the lead regulatory agency (the Central Valley Regional Water Quality Control Board [CVRWQCB])requested the RP to install groundwater monitoring wells and begin quarterly well monitoring The wells were drilled and sampled in June 2002 and placed on a schedule of quarterly monitoring This report presents the results for the third quarter of 2003 2 0 PROCEDURES Monitoring was performed on September 3, 2003 The wells were opened and the water level was allowed to equilibrate with atmospheric pressure for approximately 15 minutes before the depth to water was measured Each well was then purged of approximately 6 gallons of water, and pH, temperature, and electrical conductivity were measured at 2- gallon intervals to confirm that the standing water had been removed and these parameters had stabilized (Appendix A) Water samples were collected by lowering a disposable Teflon® bailer to the water table Three 40-m1 vials and a 1-liter bottle were collected from each well and preserved in a cooled ice chest for later shipment to the laboratory The water samples were analyzed for Total Purgeable Petroleum Hydrocarbons in the gasoline range (TPH-g), Total Extractable Petroleum Hydrocarbons in the diesel range (TPH-d), benzene, toluene, ethylbenzene, and xylene (BTEX), five gasoline oxygenates, and dichloroethane (1,2-DCA) The laboratory report is included in Appendix B, and the results are discussed in section 3 0 s 2
