1 <br /> D <br /> • 3.2 ANALYTTCAL RESULTS <br /> 1 <br /> A summary of the analytical data for the May 1999 groundwater sampling is presented in Table <br />' 3-2 Mstoncal groundwater analytical results are presented in Table A-1 in Appendix A. The <br /> analytical reports and Chain of Custody forms are presented in Appendix C <br />' Petroleum hydrocarbons were detected in samples collected from MW-2, MW-2A, MW-3A, <br />' MW-6, and NfW-7. Purgeabie petroleum hydrocarbons as gasoline occurred above the detection <br /> limit for the third time in MW-6. No petroleum hydrocarbons were detected in samples <br /> collected at MW-4, MW-5, or MW-9. <br /> 1 <br /> Table 3-2 <br />' Organic Analytical Results <br /> San Joaquin County Human Services Agency <br /> 17 through 19 May 1999 <br /> Groundwater Ethyl- <br /> Elevation Benzene Toluene benzene Total Xylene TPH-G <br />'.
