L <br /> L Section 5 <br /> L Analytical Results <br /> L <br /> Based on the results of the laboratory analyses, diesel (TPI) compounds were not reported <br /> Labove the laboratory detection limits (1 ppm for soil, 50 ppb for water) in any of the soil or <br /> groundwater samples collected for analysis. Organic lead was not reported above the detection <br /> limit of 0.75 ppm in any of the soil or groundwater samples collected for analysis. Toluene was <br /> reported at .0042 ppm in BP2-W, the down-gradient hydropunched water sample. No other <br /> LBTEX compounds were reported in sample BP2-W. BTEX compounds were not detected in any <br /> of the other soil and water samples collected. Laboratory data reports are presented in Appendix <br /> D. A summary of the laboratory data is presented in Table 5-1. <br /> TABLE 5-1 <br /> SUNIlVIARY OF LABORATORY RESULTS <br /> L-Woe (SPA 801 (EPA 820) <br /> HP1-10'(soil sample) ND ND/ND/ND/ND <br /> LHPl-W(groundwater Ie) ND ND/ND/ND/ND <br /> HP2-9'(soil sample) ND ND/ND/ND/ND <br /> LHP2-W(groundwater le) ND ND/.W42/?M/ND <br /> STP-1(soil sample) <br /> LAnalytical data reponed in ppm <br /> ND Not Detected above laboratory detection limits <br /> Detection limits are as follows: TPH(diesel) = 1 ppm for soil, 50 ppb for water <br /> LBTEX= 5 ppb for soil, 0.5 ppb for water <br /> Organic Lead = 0.75 ppm for soil and water <br /> L <br /> V <br /> L <br /> L <br /> L� <br /> TETRA TECH:Castle Rock Forest Fire Station,Preliminary Site Assessment Report Page 14 <br /> L <br />
