Groundwater and soil samples were analyzed for TPHg by EPA <br /> Method 8015 (Modified) or equivalent, benzene, toluene, <br /> ethylbenzene, and xylenes (BTEX) by EPA Method 8021B or <br /> equivalent, and fuel oxygenates (MTBE, di-isopropyl ether <br /> [D1PE], ethyl tertiary butyl ether [ETBE], TAME, and TBA) and <br /> lead scavengers (112-dichloroethane [1,2-DCA] and <br /> 1,2-dibromoethane [EDB])by EPA Method 8260B <br /> HYDROCARBON DISTRIBUTION IN SOIL <br /> Soil samples were collected from boring CPT-1 at depths of 62, 78, 88, and 99 fbg TPHg and <br /> BTEX were not detected in any of the soil samples MTBE was detected at 3 5 ppm at 62 fbg <br /> No other fuel oxygenates or lead scavengers were detected in samples from this boring <br /> Soil samples were collected from boring CPT-2 at depths of 62, 82, 91, and 100 fbg No TPHg, <br /> BTEX,fuel oxygenates, or lead scavengers were detected in samples from this boring <br /> The soil chemical analytical data are summarized in Table 2 and TPHg, benzene, and MTBE <br /> results are presented on Figure 2 The certified analytical reports for the soil samples are <br /> presented in Appendix C <br /> HYDROCARBON DISTRIBUTION IN GROUNDWATER <br /> Groundwater samples were collected from boring CPT-1 at depths of 59-62, 75-78, 88-91, and <br /> 97-100 fbg TPHg and BTEX were not detected in any of the groundwater samples from this <br /> boring MTBE was detected in each of the samples at concentrations ranging from 3 0 to <br /> 68,000 ppb, with the maximum concentrations at 59-62 fbg TAME and TBA were detected in <br /> the sample collected at 59-62 fbg at 96 and 14,000 ppb, respectively No other fuel oxygenates <br /> or lead scavengers were detected in any of the other samples from this boring <br /> Groundwater samples were collected from boring CPT-2 at depths of 61-64, 79-82, 89-92, and <br /> 97-100 fbg TPHg was detected at 77 ppb in the 79-82 fbg sample BTEX was not detected to <br /> any of the groundwater samples from this boring MTBE was detected to each of the samples at <br /> concentrations ranging from 2 8 to 5,400 ppb, with the highest concentration at 61-64 fbg TBA <br /> 0955 5 <br />
