AGE-NC Project No 97-0343 <br />' Page 2 of 6 <br />' For each sample,both ends of the leading or other selected sleeve were covered with Teflon sheets, <br /> capped and sealed with tape The samples were properly labeled,stored on Ice and transported under <br /> chain-of-custody to Cal Tech Environmental Laboratories, a State of California Department of <br />' Health Services (DHS)-certified analytical laboratory <br />' 2 2 2 Logging <br /> Soil was extruded from the remaining brass sleeves and was screened for the presence of organic <br />' vapor using an organic vapor meter(OVM) equipped with a PID,the OVM readings were recorded <br /> on a boring log The soil was then visually described on the boring log in accordance with the <br /> Unified Soil Classification System (see Appendix B) <br /> 1 <br /> 2 2 3 Well Completions <br />' Pilot boring MW8 was completed as a ground water monitoring well using two-inch diameter <br /> schedule 40 PVC casing with 0 020-Inch slotted screen Installed from approximately 90 feet to 95 <br /> feet bsg, with blank casing extended to the surface The filter pack (No 3 Lonestar sand) was <br /> installed from approximately 88 feet to 95 feet bsg A nominal 2-foot bentonite chip plug was then <br /> Installed above the filter pack and hydrated The well was then grouted to near the surface with <br /> portland cement A water-tight, traffic-rated well box was then installed over the well An as-built <br /> well diagram is depicted on the boring log in Appendix B <br /> 2 2 4 Laboratory Analyses of Soil Samples <br /> After collection, the samples were properly labeled, placed in a chilled container and transported <br /> under chain-of-custody to Cal Tech Environmental Laboratories (CTEL), a California Department <br />' of Health Services-certified analytical laboratory, for analysis The samples were analyzed for <br /> • Total petroleum hydrocarbons quantified as gasoline and diesel (TPH-g and TPH-d) in <br /> accordance with EPA Method 8015-modified for gasoline and diesel, <br /> • Benzene, toluene, ethylbenzene and total xylenes (BTEX) and the fuel additives methyl- <br /> tertiary butyl ether (MTBE), di-isopropyl ether (DIPE), ethyl-tertiary butyl ether (ETBE), <br /> tertiary-amyl methyl ether(TAME), tertiary butanol (TBA), 1,2-dibromoethane (EDB) and <br /> 1,2-dichloroethane (1,2-DCA) in accordance with EPA Method 8260B <br /> • <br /> Advanced CeoEnvironmental,Inc <br /> I <br />
