minor amounts of BTEX & TPHg, MTBE was absent <br /> SP-C; All samples were ND <br /> SP-D, Samples at 6 ' & 12 ' were ND, , BTEX & TPHg were measured in <br /> the samples from 16 ' & 21 ' MTBE was absent in all samples . <br /> SP-E, The soil samples at 6 ' and 26 ' were ND The samples from <br /> 111 , 161 , and 21 ' recorded BTEX & TPHg; the levels at 16 " were <br /> the highest of any of the soil samples MTBE was ND This probe <br /> hole was between the two pump islands, which appeared to have <br /> been a major source of contamination. <br /> SP F, The sample at 6 ' was ND The ones at 11 ' & 16 , recorded <br /> varying amounts of BTEX & TPHg, with the highest levels at 16 ' <br /> MTBE was ND <br /> SP-G; Samples at 61 , 111 , & 21' were ND Benzene was measured at <br /> . 014 mg/kg in the sample from 161 , all other components were ND . <br /> MTBE was also ND <br /> The highest levels of contamination were encountered in SP-E, <br /> SP-F, and SP-D, with lesser amounts in SP-B & SP-G <br /> Using the data from the lithologi.c plots, 6 cross-sections were <br /> constructed through the soil probes and monitoring wells, their <br /> locations are shown on PLATE IV Those cross-sections are <br /> identified as follows - A-B is PLATE VI-A, C-D is PLATE VI-B, E-F <br /> is PLATE VI-C, G-H is PLATE VI-D, I-J is PLATE VI-E, and K-L is <br /> 1 PLATE VI-F. The results of the laboratory analyses from the soil <br /> samples are shown on each cross-section <br />' PLATE VTI-A shows the laboratory results from soil samples taken <br /> at 6 ' bgl ; all were ND PLATE VII-B shows the lab results of <br /> soil samples taken from 11 ' -121 ; only SP-E & SP-F measured any <br />' <br /> contamination at that depth PLATE VII-C shows lab results of <br /> soil samples in the 14-16 ' interval SP-B, SP-D, SP-E, SP-F, <br /> SP-G, and monitoring wells MW-1 & MW-3 revealed varying amounts <br /> of BTEX & TPHg This depth range had the greatest areal extent <br />' PLATE VII-D shows the results in the interval 21 ' -231 , only SP-D, <br /> SP-E, & MW-3 recorded readings SP-A, B, & C did not penetrate <br /> to that depth PLATE VII-E shows lab results at the 25-26 ' <br />' depth; only SP-E & MW-1 & MW-2 had sample analyses at that depth, <br /> they were ND. <br />' SUMMARY OF WORK PERFORMED <br /> The work completed to date can be summarized as follows <br /> 5 <br />
