05 November 1997 AGE-NC Project No 96-0249 Page 3 of 7 sampler with 48-inch acetate sleeves Selected soil samples were preserved by covenng both ends of the selected acetate sleeve section with Teflon sheets, capping, and sealing with tape Each sample sleeve was labeled with soil probe boring designation, depth, time, date and sampler's initials The samples were stoi ed in a chilled container and transported under a chain-of-custody protocol to McCampbell Analytical Inc (MAI), a state-certified laboratory Selected samples were analyzed in accordance with EPA Method 5030/8015m for total petroleum hydrocarbons quantified as gasoline and as diesel(TPH-g and TPH-d, respectively) and in accordance with EPA Method 8020 for volatile aromatics (benzene, toluene, ethylbenzene, and total xylenes, BTE&X) with methyl tertiary butyl ether (MTBE) 34 GROUND WATER SAMPLE COLLECTION Grab ground water samples were collected from P I through P4 utilizing a hydro-punch technology A Geoprobe water sampling assembly was advanced to a depth approximately five feet below the water table utilizing hollow steel rods The hollow steel rods were then retracted upward appro-umately five feet, thereby exposing a PVC screen to ground water A bailer fitting was then placed on the end of 3/8-inch diameter polyethylene tubing, inserted through the rod assembly into the exposed screen, through which water was manually pumped Sufficient sample was collected from each soil boring to fill at least three 40-m1 EPA-approved VOA vials containing 0 5 ml 18% hydrochloric acid as a preservative and one liter amber bottle Ground water sample containers were labeled with probe boring designation-H20, date, time, and samplers initials Following collection and labeling of each grab ground water sample, the sample was immediately placed In a chilled container Each sample was logged on a chain-of-custody form and transported to MAI for analysis of TPH-g, TPH-d, BTEX and MTBE in accordance with EPA method 8015M and 8020 Volatile organics were also analyzed In sample P3-H20 in accordance with EPA method 8260 3 5 LOGGING During soil probe boring activities, sample duplicates were monitored for the presence of organic vapor using a photo-ionization detector (PID Thermo Environmental 580A, 10 0 eV, calibrated to isobutylene) and were described on boring logs using the Unified Soil Classification System (USCS) Boring logs are summarized in Appendix A Advanced GeoEncironmental,Lic.
