10 INTRODUCTION <br /> This report describes field activities that were performed during the first quarter of 2003 <br /> on behalf of Mr and Mrs James Fisk, owners of the property located at 8125 S El <br /> Dorado Street in French Camp, California(Figure 1) Mr and Mrs Fisk operate J&L <br /> Market and Service at this address, and have been designated by the State Water <br /> Resources Control Board UST Cleanup Fund as the Responsible Party (RP) for <br /> petroleum contamination related to underground fuel tanks at that facility <br /> Contamination was discovered during the removal of three single-walled UST's and <br /> related piping in November 1995, and extensive interim remediation 1n the form of soil <br /> excavation then took place Upgradient Environmental Consultants (Upgradient <br /> Environmental) conducted further investigation in November 2001 to determine whether <br /> groundwater was impacted by the petroleum release, and submitted a Preliminary <br /> Investigation and Evaluation Report (PIER) in December 2001 Because evidence of <br /> groundwater contamination was obtained, the lead regulatory agency (the Central Valley <br /> Regional Water Quality Control Board [CVRWQCB]) requested the RP to install <br /> groundwater monitoring wells and begin quarterly well monitoring The wells were <br /> drilled and sampled in June 2002 and placed on a schedule of quarterly monitoring This <br /> report presents the results for the first quarter of 2003 <br /> 2.0 PROCEDURES <br /> Monitoring was performed on March 26, 2003 The wells were opened and the water <br /> level was allowed to equilibrate with atmospheric pressure for approximately 15 minutes <br /> before the depth to water was measured Each well was then purged of approximately 10 <br /> gallons of water, and pH, temperature, and electrical conductivity were measured at 2- <br /> gallon intervals to confirm that the standing water had been removed and these <br /> parameters had stabilized (Appendix A) <br /> Water samples were collected by lowering a disposable Teflon® bailer to the water table <br /> Three 40-m1 vials were collected from each well and preserved in a cooled ice chest A 1-, <br /> liter bottle was also collected from JLM-3 and JLM-5 <br /> The water samples were shipped to McCampbell Analytical Laboratory in Pacheco, <br /> where they were analyzed for Total Purgeable Petroleum Hydrocarbons in the gasoline <br /> range (TPH-g), Total Extractable Petroleum Hydrocarbons in the diesel range (TPH-d), <br /> benzene, toluene, ethylbenzene, and xylene (BTEX), five gasoline oxygenates, and <br /> dichloroethane (1,2-DCA) The laboratory report is included in Appendix B, and the <br /> results are discussed in section 3 0 <br /> 2 <br />
