I <br /> chennical analysis was labeled and placed in a cooler containing ice pending delivery to a California state-certified <br />' laboratory Soils were analyzed for TPH as gasoline(TPHg),TPH as diesel (TPHd), TPH as motor oil (TPHmo), <br /> and BTEX using EPA Method 8015-M/8020 and 5520 All samples retained by this procedure were recorded <br /> on Cham-of-Custody Records which accompanied the samples to the laboratory and are included as Appendix <br />' B <br /> To further define the types of hydrocarbons encountered on the site, the soil samples collected in February were <br />' submitted to Zymax Enviroteclinology,Inc (Zyinaa) for analysis for benzene,toluene,ethylbenzene and xylenes <br /> (BTEX), TPH C4-C40, and naphthalene using a combination of GC/MS for EPA Method 8260 and 8270 <br /> protocol All samples retained by this procedure were recorded on Cham-of-Custody Records,which accompanied <br />' the samples to the laboratory and are included as Appendix C <br /> The boreholes were abandoned by backfilling the borehole to the surface with cement grout, and resurfacing with <br />' asphalt <br /> 222 Groundwater Grab Sampling and Analysis <br />' SECOR collected groundwater grab samples from the soil boring locations Groundwater grab samples were <br /> collected by advancing the borehole 2 feet into the saturated soil A 2-inch diameter section of slotted PVC pipe <br />' was installed to the bottom of the borehole within the casing Groundwater was allowed to stabilize within the <br /> PVC pipe and groundwater samples were then collected by lowering a clean stainless steel bailer into the <br /> temporary PVC pipe Growidwater samples were transferred directly from the bailer into three 40-mi VOA vials <br /> and an amber one-literjar Care was taken when transferring the water from the bailer to the containers to avoid <br /> turbulence as much as possible The containers were filled and capped so that no air bubbles were trapped <br /> Sample containers were labeled and immediately placed in a cooler containing ice for delivery to the analytical <br /> laboratory <br /> Following sample collection,the.slotted PVC casing was removed from the borehole,steam-cleaned and properly <br /> disposed <br /> Groundwater samples collected during the January sampling were submitted to Superior Analytical accompanied <br /> by a completed chain-of-custody form Groundwater grab samples were analyzed for TPHg,TPHd,TPHmo, and <br />' BTEX using EPA Method 8015-M/8020 and 5520 All samples retained by this procedure were recorded on <br /> Chani-of-Custody Records, which accompanied the samples to the laboratory and are included as Appendix D <br />' To further define the types of hydrocarbons encountered on the site, the groundwater samples collected in <br /> February were submitted to Zyinaa for analysis for benzene,toluene,ethylbenzene and xylenes(BTEX),TPH <br /> C4-C40,and naphthalene using a combination of GC/MS for EPA Method 8260 and 8270 protocol All samples <br />' retained by this procedure were recorded on Chain-of-Custody Records,which accompanied the samples to the <br /> laboratory and are included as Appendix.
