�J,NW04 <br /> Working To Restore Nature <br /> 1992 (Figure 2). Soil samples were collected from the borings between the depths of 5.5 and <br /> 11 feet. TPHd was detected in the samples collected from boring SBI (installated within the <br /> f former tank pit ). Low concentrations of aromatics were also detected in these samples. <br /> Petroleum hydrocarbon analytes were not detected in the samples collected from boring SB2, <br /> 1 located east of the tank pit. Soil sample results are summarized in Table 2. <br /> 0 During October 1992, the former diesel tank location was excavated until all residual <br /> contaminated soil which was physically accessible was removed. The excavated area is shown <br /> on Figure 2. Analysis of confirmation soil samples collected from the side walls of the <br /> excavation indicated that some residual petroleum hydrocarbons remained along the west wall <br /> beneath the equipment storage building. Analytical results are summarized in Table 2. <br /> �l �P g g• Y <br /> f <br /> In order to investigation the extent of residual soil contamination beneath the building two soil <br /> frr borings (BIW and B2W) were drilled and sampled on June 25, 1993. The locations of the <br /> =` borings are shown on Figure 2. <br /> yy. <br /> Four soil samples were collected from boring BIW, and two were collected from boring B2W. <br /> Collected samples were analyzed for BTEX, and TPHd. <br /> Petroleum hydrocarbon analytes were not present at or above method detection limits in either <br /> Ff" sample collected from boring B2W. Petroleum hydrocarbon analytes were present in the soil <br /> samples collected from boring BIW between the depths of 7.5 and 9.25 feet. No analytes were <br /> detected in the sample collected from BIW at a depth of 6 feet. Benzene was not detected in <br /> any sample (Table 2). <br /> c.. <br /> F'=� J <br /> 0W01951REP0RT51CL012594.FNL 4 <br />
