k" KLEiNFLLDER <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 />Soil samples were collected for lithologic classification every five feet during advancement of <br />four well borings (1\4W-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 />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 />363741 ST03R1919 Page 15 of 19 <br />(i 2004 Kleinfelder, Inc.
