1 <br /> f Page 4 <br /> I <br /> These soil samples were collected on November 13, 1998, in the following manner. Each <br /> soil sample was obtained by inserting a brass, two-inch diameter by six-inch long brass <br /> sleeve into the soils. A soil slide hammer was used to insert the sleeves into the soil, each <br /> end was wrapped with teflon, sealed with plastic end caps and wrapped with tape. <br /> The samples were labeled, logged on a Chain of Custody form and transported on blue ice <br /> to Acculabs Inc., (State of California, environmental laboratory, certification number <br /> 2330), to perform the required analysis, (Chain of Custody form is presented in Appendix <br /> C). <br /> Soil Analytical Results <br /> Soil samples from the diesel tank excavation, and sock piles, were analyzed for Total <br /> Petroleum Hydrocarbons as diesel and for Benzene, Toluene,Ethylbenzene, Xylene <br /> (BTEX) by EPA methods 8020 and 8015M. <br /> Excavation Soil Sample Results <br /> The analytical results for tank pit sample, T-W.1(14), taken from the west end of pit <br /> bottom at an estimated depth of 14'6" detected 4,900 ppm as TPH-D(Total Petroleum <br /> Hydrocarbons as Diesel), detected Non-Detect as Benzene, detected Non-Detect as <br /> Toluene, detected Non-Detect as Ethylbenzene, detected Non-Detect as Xylenes. <br /> The analytical results for tank pit sample, T-E.1(14), taken from the east end of pit <br /> bottom at an estimated depth of 14' detected 410 ppm as TPH-D (Total Petroleum <br /> Hydrocarbons as Diesel), detected Non-Detect as Benzene, detected .02I mg/Kg(.021 <br /> parts per million) as Toluene, detected Non-Detect as Ethylbenzene, detected Non-Detect <br /> as Xylenes. <br /> The analytical results for excavation soil pile sample SP-1 A,1,1 A2 collected from <br /> excavation soils at the west end of soil pile, detected 450 ppm as TPH-D (Total <br /> Petroleum Hydrocarbons as Diesel), detected Non-Detect as Benzene, detected 0.050 <br /> mg/Kg(0.026 parts per million) as Toluene, detected Not-Detected as Ethylbenzene, <br /> detected 0.025 mg/Kg(0.025 parts per million) as Xylenes. <br /> i <br /> The analytical results for excavation soil pile sample SP-IB,1,1B2 collected from <br /> excavation soils at the east end of soil pile, detected 200 ppm as TPH-D (Total Petroleum <br /> i Hydrocarbons as Diesel), detected Non-Detect as Benzene, detected 0.014 mg/Kg (0.014 <br /> 1 parts per million) as Toluene, detected Not-Detected as Ethylbenzene, detected Not- <br /> Detected as Xylenes. <br /> 4fi <br /> 1 <br />
