I <br />' 13 April 2005 <br /> • AGE-NC Project No 01-0827 <br />' Page 3 of 7 <br />' the boring logs After sample recovery,both ends of the second or other selected sleeve were covered <br /> with Teflon sheets,capped and sealed with tape The sample sleeves were labeled,stored on Ice and <br /> transported under chain of custody to Cal Tech Environmental Laboratories (CTEL), a State of <br />' California DHS-certified analytical laboratory <br /> 2 2 2 Logging <br /> Soil was extruded from a second brass sleeve and screened for the presence of organic vapor using <br />' an organic vapor meter (OVM) equipped with a photo-Ionization detector (PID Thermo <br /> Environmental 580, 10 0 eV, calibrated to Isobutylene), the OVM readings were recorded on the <br /> boring log The soil was then visually described by and AGE geologist in accordance with the <br /> Unified Soil Classification System (see Appendix C) <br />' 2 2 3 Well Completions <br /> Pilot boring OZ was completed using 1-Inch diameter PVC casing,with a 50 micron grade diffuser <br />' screen installed from 30 to 32 feet bsg, then a filter pack (No 3 Lonestar sand) was installed from <br /> total depth to 1-foot above the diffuser screen, and 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, and a water-tight, traffic-rated well box was Installed over the well An as-built <br /> well diagram is depicted on the boring log in Appendix C <br /> 1 <br /> 2 2 4 Laboratory Analysis of Soil Samples <br /> iA total of three selected soil samples were analyzed for <br /> • Total petroleum hydrocarbons quantified as gasoline (TPH-g) in accordance with EPA <br /> Method 8015 Modified, <br />' • Benzene, toluene, ethylbenzene and total xylenes (BTEX), and the fuel oxygenated <br /> compounds tertiary butanol (TBA), di-isopropyl ether (DIPE), ethyl tertiary-butyl ether <br /> (ETBE), tertiary-amyl methyl ether (TAME), methyl-tertiary-butyl ether (MTBE), <br /> 1,2-dichloroethane (1,2-DCA) and 1,2-dibromoethane (EDB) by EPA Method 8260 <br /> I <br /> Advanced GeoEnvironmental,Inc <br /> I <br />
