1 <br /> V j <br /> k <br /> The results indicated that the petroleum constituents were not present in the soil in the north and <br /> east walls of the excavation, but that petroleum constituents were present in the soil near the <br /> . center of the floor of the excavation. <br /> �E <br /> Permission was obtained from SJHD to excavate additional soil as needed to remove all soil <br /> n December 20 1991 and additional <br /> containing petroleum constituents. Excavation continued o , <br /> gP <br /> + soil was removed from the west end and the floor of the pit. This soil was placed in stockpile <br /> SP-2. The final configuration of the pit is indicated on Figures 4 and 5. Soil samples E-4, E-5, <br /> and E-6 were collected from the west wall at a depth of 20 feet, the south wall at a depth of 18 <br /> r feet and the floor at a depth of 20 feet, respectively. Sample locations are indicated on Figures <br /> 4 and 5. These samples were collected from the excavator bucket and transported to the <br /> k � <br /> laboratory for analysis for BTEX and TPH-D as previously described. Analytical results are <br /> r <br /> j presented in Table 5, and laboratory reports are included in Appendix E. <br /> After the completion of excavation, soil samples were collected from the stockpiles to determine <br /> concentrations of petroleum constituents for soil disposal purposes. At the direction of SJHD, <br /> four samples were collected from stockpile SP-1 and composited, two samples were collected <br /> : a <br /> from stockpile SP-2 and composited, and two samples were collected from stockpile SP-3 and <br /> composited. Sample locations are indicated on Figure 3, and analytical results are presented in <br /> Table 6.
