1-4 Soil and Groundwater Sample Laboratory Analyses <br /> The soil and groundwater samples were submitted to Kiff Analytical LLC(Kiff)located in Davis,California <br /> Kiff is a California-certified analytical laboratory, for analysis Chain of custody procedures, including the <br /> use of chain of custody forms, were used to document sample handling and transport from the time of <br /> collection to delivery to the laboratory for analysis The chain of custody forms and laboratory analytical <br /> reports are presented in Appendix 5 Kiff Analytical report numbers 34597,34755,and 34808 are included <br /> in Appendix V of this report <br /> The analyses were conducted on a normal turn-around basis in general accordance with U S Environmental <br /> Protection Agency(USEPA)specified holding times All analyses were conducted with USEPA Test Method <br /> 8260B protocol The soil samples collected from each soil boring were analyzed for TPH-gasoline using <br /> 8260B protocol Benzene,toluene,ethylbenzene,and xylene as well as selected gasoline oxygenates/additives <br /> were determined by USEPA Test Method 8260B The selected oxygenates/additives that were analyzed for <br /> include ethanol(E),tertiary-butanol(TBA),Di-isopropyl Ether(DIPE), Ethyl tertiary-butyl ether(ETBE), <br /> tertiary-amyl methyl ether(TAME),methyl tertiary butyl ether(MTBE) Lead scavengers were analyzed and <br /> included 1,2- Dichloroethane (1,2-DCA) and 1, 2- Dibromoethane (1,2-EDB) Groundwater samples <br /> collected from the soil borings and monitoring wells were submitted for analysis using USEPA Test Method <br /> 8260B for the same petroleum hydrocarbon constituents described above Analytical results are presented <br /> in Tables 3 and 4 <br /> 3_5 Investigation Derived Waste Disposal <br /> Drill cuttings generated during the field investigation were contained for disposal on visqueen sheets and <br /> stockpiled at the site Total volume generated was less than 5 cubic yards of soil This soil was sampled <br /> on November 25, 2003 and analyzed using USEPA Test Method 8260B for determination of appropriate <br /> disposal and/or remediation Concentrations of TPH-gas, BTEX, 5 oxygenates, and lead scavengers were <br /> reported to be below analytical detection limits <br /> Mam1D 1EnwromnenW\Pan=TexacoaeportslSAR1203 wpd Page 17 <br />
