Soil Classification System The lowermost intact sample from each interval was retained for <br /> possible analysis The sample ends were covered with Teflon TM sheets and tight fitting plastic <br /> caps Once labeled and sealed, the samples were placed in an ice-chilled cooler Each sample <br /> was identified on a chain-of-custody form, which followed the samples to the analyzing <br /> laboratory A diagram illustrating the piston sampler utilized by Gregg In Situ, Inc is included <br /> in Appendix C Soil and groundwater sampling intervals, and soil descriptions, are presented on <br /> the borehole sampling logs included in Appendix D <br /> Analytical Methods <br /> Soil and groundwater samples were forwarded to Alpha Analytical, Inc , a California state- <br /> certified laboratory (ELAP #2019), for chemical analysis under strict chain-of-custody <br /> procedures Soil and groundwater samples were analyzed for TPHG using USEPA Method <br /> 8015B, and for BTEX, MTBE, TBA, ethyl tertiary butyl ether (ETBE), di-isopropyl ether <br /> (DIPE), tertiary amyl methyl ether (TAME), ethanol, methanol, 1,2-dichloroethane (1,2-DCA), <br /> and dibromoethane (EDB) using USEPA Method 8260B Soil analytical results are presented in <br /> Table 2, and groundwater analytical results are presented in Table 3 Certified Analytical <br /> Reports with chain-of-custody records are presented in Appendix E <br /> • <br /> K\USA Gasoline\0835\Reports\usa835-scm-assessment-report doc Page 7 5TRATU5 <br />
