11 <br /> 6 0 LABORATORY ANALYTICAL RESULTS <br /> The final laboratory reports for chemical analyses performed on the soil and ground <br /> water samples are presented in Appendix E Table 2 summarizes the results of the <br /> isoil boring and ground water samples Figure 3 shows the location of organic <br /> compound concentrations detected during the November 5, 1992, ground water <br /> sampling event Figure 4 shows the organic compound concentrations that were <br /> detected in the soil The following sections describe the results of the sample <br /> analyses <br /> 6 1 Results of Soil Sample Analysis <br /> Toluene and EDB were not detected in any of the samples collected from the soil <br /> borings TPH-G and xylenes were detected in soil samples collected from W-2, W-3, <br /> and W-4 The sample collected from a depth of 10 0 feet to 10 5 feet in W-4 was <br /> found to contain the highest concentration of contaminants, TPH-G, ethylbenzene, <br /> and xylenes were indicated at 290, 3 4, and 30 parts per million (ppm), respectively <br /> Ethylbenzene was not detected in soil samples collected from W-1 or W-2, or from <br /> W-5 through W-7 Benzene was detected at a concentration of 0 0060PP m in a <br /> sample from W-3 collected at a depth interval of 14 0 to 14 5 feet <br /> 6 2 Results of Ground Water Analysis <br /> Ground water sampling results indicate that TPH-G, benzene, toluene, ethylbenzene, <br /> and EDB are not present in the ground water at the Site However, xylenes were <br /> detected at a concentration of 0 00055 ppm, barely over the 0 0005 detection level, <br /> in Well W-3 Coliform bacteria and fecal coliform were present in the ground water <br /> sample collected from W-5 <br /> POW V91 6341REPORMSITE ASSVMANTECAVMANTECA APT IAPr 26 031 CsnonleEnvlronmental <br />
