22 May 2002 <br /> AGE-NC Project No.01-0877 <br /> Page 5 of 9 <br /> define the vertical extent of soil and ground water at the site.Proposed well locations are illustrated <br /> in Figure 2. <br /> The borings will be advanced utilizing a truck-mounted, hollow stem drill rig equipped with <br /> 8.25-inch diameter hollow-stem augers. The proposed ground water monitoring well borings will <br /> be advanced to approximately 40 feet below surface grade (bsg). The proposed soil boring will be <br /> advanced to approximately 70 feet bsg,or until petroleum hydrocarbons are no longer detected from <br /> two consecutive soil samples as determined by field observation and field screening using an organic <br /> vapor monitor(OVM).However, total depths of all borings may vary according to site conditions <br /> 1 encountered during drilling. <br /> J Selected soil samples will be analyzed by a California Department of Health Services (DHS)- <br /> certified laboratory for the following constituents: <br /> • TPH-g, TPH-d and TPH-mo by EPA Method 8015 Modified; <br /> Benzene, toluene, ethylbenzene and total xylenes (BTEX)by EPA Method 8260. <br /> • Fuel additives including methyl tertiary butyl ether(MTBE), tertiary-butyl alcohol (TBA), <br /> di-isopropyl ether (DIPE), ethyl tertiary-butyl ether (ETBE), tertiary-amyl methyl ether <br /> - (TAME) ethylene dibromide (EDB) and 1,2-dichloroethane (1,2-DCA) by EPA Method <br /> l 8260. <br /> l A grab ground water sample will be collected from the total depth of the deep soil boring utilizing <br /> a hydro-punch sampling tool; the water sample will be analyzed by a DHS-certified laboratory for <br /> ( j the following constituents: <br /> • TPH-g, TPH-d and TPH-mo by EPA Method 8015 Modified; <br /> BTEX by EPA Method 8260. <br /> • Fuel additives MTBE, TBA, DIPE, ETBE, TAME, EDB and 1,2-DCA by EPA Method <br /> 8260. <br /> Laboratory reports for the soil and grab ground water analyses, testing methods, laboratory quality <br /> i assurance/quality control (QA/QC) reports, and sample chain of custody documentation will be <br /> presented in a report with findings and recommendations. <br /> I— <br /> 1 Advanced GcoEnvhonmental,Inc. <br /> I <br /> I <br />
