Well borings S-5 and S-6 were drilled north of the site on Elmwood Avenue Soil samples collected <br /> from 15 fbg, from both borings, did not contain detectable levels of TPPH, benzene, or fuel <br /> oxygenates <br /> The soil chemical analytical data are summarized in Table 2 and presented on Plate 2 The certified <br /> analytical reports are presented in Appendix D <br /> Hydrocarbon Distribution in Ground Water <br /> Ground water samples were collected from CPT-1 at depths of 40, 50, and 60 fbg, and from CPT-2 <br /> at depths of 40 and 60 fbg An attempt was made to collect a water sample at 50 fbg from CPT-2, <br /> but the formation did not produce sufficient ground water for sample collection at this depth <br /> The ground water sample from CPT-I at 40 fbg contained 620 ppb TPPH, 280 ppb TEPH, 14 ppb <br /> benzene, and 3 1 ppb MTBE The EPA 8260 analysis did not confirm the presence of MTBE in the <br /> ground water sample from 40 fbg The ground water samples from CPT-1 at 50 and 60 fbg did not <br /> contain detectable concentrations of TPPH, benzene, and fuel oxygenates, but contained 88 and 97 <br /> ppb TEPH, respectively Fuel oxygenates were not detected in the ground water samples collected <br /> from CPT-1 <br /> The ground water sample from CPT-2 at 40 fbg contained 680 ppb TPPH, 420 ppb TEPH, 21 ppb <br /> benzene, and 8 6 ppb MTBE The EPA 8260 analysis confirmed the presence of MTBE in this <br /> sample at 7 1 ppb The ground water sample from 60 fbg contained 110 ppb TPPH, 110 ppb TEPH, <br /> and 2 7 ppb benzene MTBE and other fuel oxygenates were not detected in the ground water sample <br /> from 60 fbg <br /> Ground water samples collected from Well S-1 contained 1,400 ppb TPPH, 1,200 ppb TEPH, 45 ppb <br /> benzene, and X10 ppb MTBE Fuel oxygenates were not detected in the ground water samples <br /> collected from this well with the exception of 49 ppb DIPE <br /> Ground water samples collected from Well S-2 contained 23,000 ppb TPPH, 7,800 ppb TEPH, 190 <br /> ppb benzene, and 120 ppb MTBE The EPA 8260 analysts did not confirm the presence of MTBE <br /> detected by the EPA 8020 analysis Fuel oxygenates were not detected in the ground water samples <br /> collected from this well <br /> Ground water samples collected from Well S-3 contained 530 ppb TPPH, 530 ppb TEPH, 53 ppb <br /> benzene, and non-detectable levels of MTBE Fuel oxygenates were not detected in the ground water <br /> samples collected from this well with the exception of 200 ppb DIPE <br /> 240-0943 6 <br />
