i <br /> 01 November 2000 <br /> AGE-NC Project No 95-0173 <br /> Page 2 of 6 <br /> I 30 inches The number of blows required to drive each 6-inch length of the sampler (blow counts) <br /> was recorded on boring logs by an AGE staff geologist <br /> Soil samples were preserved by covering both ends of the second brass sleeve with Teflon sheets, <br /> capping and sealing with tape Each preserved sample sleeve was labeled with soil boring location, <br /> depth, time, date and sampler's initials <br /> ISelected preserved samples were logged on a chain-of-custody form, placed in a chilled container <br /> and transported to a California Department of Health Services(DHS)-certified laboratory for analysis <br /> for <br /> • Total petroleum hydrocarbons quantified as gasoline and diesel (TPH-g and TPH-d, <br /> Irespectively)by EPA Methods 3550/5030/8015M, <br /> • Volatile aromatic compounds - benzene, toluene, ethyl benzene and xylene (BTEX) with <br /> Imethyl-tertiary butyl ether(MTBE) by EPA Method 8020, and <br /> • Fuel oxygenated compounds - 1,2-dichloro ethane (1,2-DCA), ethylene dibromide (EDB), <br /> methanol, ethanol, tertiary butanol (TBA), di-isopropyl ether(DIPE), ethyl tert butyl ether <br /> (ETBE), tert amyl methyl ether (TAME) and MTBE by EPA Method 8260 Modified <br /> The results of the soil analyses are contained in Table 1 <br /> I2 3 EQUIPMENT DECONTAMINATION <br /> The hollow stem augers were steam cleaned prior to each bore hole advancement Sampling tools <br /> Iand brass sleeves used for sample collection were thoroughly washed with a solution of Alconox, <br /> and were thoroughly rinsed with clean tap water prior to each sampling run At the conclusion of <br /> I field activities, all rinseate generated from decontaminating the equipment was placed in properly <br /> labeled DOT-approved model 17H 55-gallon drums and was stored on-site in an area lacking public <br /> access <br /> 1 <br /> 24 SOIL BORING LOGS <br /> During drilling, sample duplicates were visually described on boring logs in accordance with the <br /> Unified Soil Classification System (USCS) Boring logs are included as Appendix A <br /> Advanced GeoEnvironmental,Inc <br /> I <br />
