i, d •CAMBRIA Soni samples were collected from boring CPT-7 at 10, 50, 70, 100, 108, 116, and 125 fbg to assess the vertical extent of petroleum hydrocarbons in the soil TPHg was detected in soil samples from boring CPT-7 at concentrations of 12 ppm at 50 fbg, 7 2 ppm at 100 fbg, and 2 1 ppm at 125 fbg Benzene was detected to soil samples from boring CPT-7 at 0 0057 ppm at 50 fbg, 0 041 ppm at 70 fbg, 0 061 ppm at 100 fbg, and 0 084 ppm at 125 fbg No fuel oxygenates or lead scavengers were detected to any of the soil samples from boring CPT-7 The soil chemical analytical data are summarized in Table 2 and is presented on Figure 2 The certified analytical reports for the soil samples are presented in Appendix C HYDROCARBON DISTRIBUTION IN GROUNDWATER Groundwater samples were collected from boring CPT-5 at depths of 110, 120, and 130 fbg TPHg was detected in groundwater samples from boring CPT-5 at concentrations of 330 parts per billion (ppb) at 110 fbg, 14,000 ppb at 120 fbg, and 110 ppb at 130 fbg Benzene was detected in groundwater samples from boring CPT-5 at concentrations of 100 ppb at 110 fbg, 280 ppb at 120 fbg, and 3 0 ppb at 130 fbg MTBE was detected in groundwater samples from boring • CPT-5 at concentrations of 2 7 ppb at 110 fbg, and 26 ppb at 120 fbg No other fuel oxygenates or lead scavengers were detected in groundwater samples from boring CPT-5 Groundwater samples were collected from boring CPT-6 at depths of 65, 73, and 80 fbg TPHg was detected in a groundwater sample from boring CPT-6 at 65 fbg at a concentration of 320 ppb Benzene was detected in the groundwater sample from boring CPT-7 at 65 fbg at a concentration of 12 ppb MTBE was detected in the groundwater sample from boring CPT-6 at 73 fbg at a concentration of 12 ppb 1,2-DCA was detected in a groundwater sample from boring CPT-6 at 80 fbg at a concentration of 2 0 ppb No other fuel oxygenates or lead scavengers were detected in any of the groundwater samples from boring CPT-6 Groundwater samples were collected from boring CPT-7 at depths of 65, 75, 83, 93, 113, and 130 fbg TPHg was detected in groundwater samples from boring CPT-7 at concentrations ranging from 640 to 47,000 ppb Benzene was detected in groundwater samples from boring CPT-7 at concentrations ranging from 3 6 to 19,000 ppb No fuel oxygenates or lead scavengers were detected in groundwater samples from boring CPT-7 Groundwater data are summarized in Table 3 and presented on Figure 3 The certified analytical reports for the groundwater samples are presented in Appendix C 1399 4
