Ground water sample containers were labeled.:with the-boring designation, date, time, and <br /> sampler's initials and were placed in a chilled container under ice. ; <br /> The water sample was logged on a chain-of-custody and transported to a DHS-certia ied laboratory <br /> and analyzed for: <br /> • TPH-g in accordance with EPA Method GCFID 5030A; <br /> • TPH-d in accordance with EPA Method 5030/8015M; <br /> • TPH-mo in accordance with EPA Method 3550/8015M; and <br /> • BTEX with MTBE in accordance with EPA method 8020. <br /> I� <br /> I <br /> 3.3. LOGGING <br /> During probe boring activities. sample duplicates were monitored for the presence of organic vapor <br /> (OV) using an organic vapor meter equipped with a photo-ionization detector (PID: Thermo <br /> Environmental 580A, 10.0 eV, calibrated to isobutylene) and were visually described on the boring <br /> log in accordance with the Unified Soil Classification System (USCS). The boring.log is included <br /> in Appendix A. <br /> G <br /> 3.4. EQUIPMENT DECONTAMINATION <br /> All probing rods used were cleaned prior to the advancement in the probe boring location. Sampling <br /> tools and brass sleeves used for sample collection were thoroughly washed in a solution of Alconox <br /> and rinsed with clean tap water prior to each sampling run. The continuous core Teflon sleeves were <br /> new and clean. <br /> 4.0. FINDINGS <br /> Soil descriptions (lithologies),were determined from field data. Hydrocarbons were not encountered <br /> in soil or ground water at detectable concentrations in field samples screened or in laboratory <br /> samples analyzed. <br /> i <br /> Advanced Gentmvironmental,Inc. i <br /> l <br /> Fa.. 1 <br />
