16 Based on these results, POI conducted a soil sampling and soil removal event <br /> in November 1996 Shallow soil samples collected at approximately 1 foot bsg <br /> were obtained from 18 locations around the two compressors pads and <br /> analyzed for extractable TPH and VOCs by a mobile lab The results of this <br /> sampling are presented in Table 2, laboratory reports are presented in <br /> Appendix A The sample locations are shown on Figure 4 Based on the <br /> results of these analyses and the previous TES sampling, POI excavated and <br /> disposed of soil from the eastern edge of the K-3 compressor pad, along the <br /> ' perimeter of the K-4 compressor pad, and in the vicinity of the hazardous <br /> material storage area <br /> During excavation at the eastern edge of the K-3 pad, soil samples were <br /> collected from locations K3-D1, K3-D2, K3-D3 and K3-D4 and K3-D7 after the <br /> excavation of 1 foot of soil The results of this sampling are presented in Table <br /> 3 and laboratory reports are included in Appendix A Sample locations are <br /> shown on Figure 5 Locations K3-D2, K3-D3, and K3-D4 contained TPH as <br /> motor oil In addition, K3-D2 and K3-D4 contained TPH as diesel Soil <br /> excavation continued at these locations to a depth of 2 5 feet bsg Samples K3- <br /> D5 and K3-D6 were collected at 2 5 feet bsg from the same location as K3-D4 <br /> and K3-D2, respectively Both of the deeper samples did not contain detectable <br /> concentrations of extractable TPH <br /> At the K-4 compressor pad, eight soil samples were collected from a depth of 1 <br /> foot bsg Soil sample locations are presented on Figure 5, analytical results are <br /> presented in Table 3 and laboratory reports are included in Appendix A A low <br /> concentration of TPH as diesel was detected in sample K4-D8 located on the <br /> northeastern corner of pad K-4 Low concentrations of acetone were detected in <br /> itwo locations (K4-D3 and K4-D8) <br /> Soil was excavated to a depth of 3 feet in the former hazardous material storage <br /> area Nine soil samples were collected during excavation activities to determine <br /> the extent of the impacted soil Figure 5 shows the approximate extent of <br /> excavation and the sample locations Analytical results for samples collected <br /> during <br /> Page 2 <br />
