h'9 KLEINEELDER <br /> of the southern excavation at depth from 25 to 45 feet with the highest petroleum concentrations <br /> at approximately 30 feet bgs. For a detailed listing of results see Table 8. <br /> WELL BORING SOIL SAMPLING RESULTS <br /> j Soil samples were collected for lithologic classification every five feet during advancement of <br /> four well borings (MW-1 through MW-4). No soil discoloration or unusual odors were noted <br /> either from soil cuttings or from the soil samples collected. A single soil sample was collected <br /> and submitted for analyses from each well boring at depths estimated just above first encountered <br /> groundwater. For a listing of results see Table 8. These four soil samples were collected at <br /> depths ranging from 46 to 56 feet bgs and were analyzed for various petroleum constituents as <br /> 3 listed in Section 4.2. None of the requested petroleum constituents were detected at or above <br /> laboratory reporting limits. Based on these field observations and soil sampling results, it does <br /> not appear that soils have been impacted by petroleum constituents at these locations. However, <br /> it should be noted that soils may become impacted due to the petroleum constituents detected in <br /> groundwater at the MW-4 location near first encountered groundwater including zones in which <br /> groundwater may fluctuate seasonally. <br /> P <br /> 1 <br /> p{ <br /> Z <br /> i <br /> I <br /> t <br /> Y <br /> v <br /> Y <br /> 36274/ST03RI919 Page 15 of 19 <br /> ?)2004 Kleinfelder,Inc.
