I <br /> 21 August 2000 <br /> . AGE-NC Project No 95-0104 <br /> Page 3 of 6 <br /> Teflon sheets,capping,and sealing with tape Each sample sleeve was labeled with soil probe bonng <br /> location, depth, time, date and sampler's Initials The samples were stored on Ice and transported <br /> under chain-of-custody to McCambell Analytical, Inc (MAI), a State of California Department of <br /> Health Services (DHS)-certified analytical laboratory <br /> 25 LOGGING <br /> Soil was extruded from a second brass sleeve or from the unpreserved portions of the soil in the core <br /> barrel samples and were screened for the presence of organic vapor using an organic vapor meter <br /> (OVM) equipped with a photo-ionization detector (PID Thermo Environmental 580A, 10 0 eV, <br /> calibrated to isobutylene),and the OVM readings were recorded on the boring log The soil was then <br /> visually described in accordance with the Unified Soil Classification System (see Appendix B) <br /> 2 6 PROBE BORING COMPLETION <br /> Borings P1 and P2 were permanently sealed to prevent vertical migration of contaminants Soil <br /> borings P 1 and P2 were abandoned by backfilling with portland cement slurry from the total depth <br /> to surface grade <br /> 27 LABORATORY ANALYSES OF SOIL SAMPLES <br /> Selected soil samples were analyzed for <br /> • TPH-g and TPH-d in accordance with EPA Methods 8015 Modified, <br /> • BTEX with MTBE in accordance with EPA Method 8020, <br /> DIPE, ETBE, MTBE, TAME and TBA in accordance with EPA Method 8260 Modified, <br /> I3.0. FINDINGS <br /> Ground water flow direction and gradient were inferred from data collected in the field,ground water <br /> levels were within the screen interval of wells MW 1 and VW 1 and above the screened intervals in <br /> wells MW5 and MW6 The hydrocarbon impact to soil and ground water was quantified by the <br /> laboratory data obtained from the soil and ground water samples <br /> Advanced GeoEnvironmental,Inc <br />
