The locations of the soil samples are shown on the <br />attached Site Sketch Map. <br />The water that accumulated in the open excavation was pumped out and <br />stored in a poly tank. Approximately 400 gallons of water was pumped <br />from the excavation into the tank. During the pumping, the water in the <br />excavation was never fully evacuated, however, the water level was <br />lowered such that groundwater was observed flowing into the excavation. <br />The soil samples were collected using a hand sampler which contained a <br />two-inch diameter, six-inch long brass liner. Prior to sampling, The <br />sampler and brass liners were cleaned with a trisodium phosphate solution, <br />rinsed with clean water and then deionized water. The soil samples were <br />rubber -capped, refrigerated and transported under chain--of-custody to the <br />analytical laboratory. <br />The water sample was retrieved from the pit excavation approximately one <br />hour after the pumping was completed. The sample was taken using a <br />teflon bailer cleaned as described for the brass tubes. The water sample <br />was transferred into glass containers which had been prepared by the <br />analytical laboratory. After the sample was obtained it was refrigerated <br />and transported under chain -of -custody control to the laboratory. <br />ANALYTICAL TESTING RESULTS <br />The analytical testing program consisted of the following analyses: <br />Test Name <br />Total Petroleum Hydrocarbons <br />("gasoline") with <br />Benzene, toluene, xylene, <br />ethylbenzene (BTXE) <br />EPA Test Method <br />5020/8015-5030/8015 (GUID) <br />8020/602 <br />The analytical results of the second round of testing were all below <br />detection levels, excepting the water sample, which had detectable gasoline <br />(but not at quantifiable levels) and 25 parts per billion (ppb) xylenes. <br />The complete analytical test data, including the chain -of --custody record, <br />are presented in the attached Appendix A. <br />FTNniN(1S <br />The initial round of analytical testing by Precision Industries, of native <br />soils at the project site, discovered no detectable hydrocarbon <br />contamination. Nor did our second round of analytical testing of native <br />soils and backfill soils detect any hydrocarbons contamination. <br />Koldveer Associates <br />
