PRIVILEGED & CONFIDENTIAL TPH in Sail Two samples collected from Boring B4 (B4-45 and B4-55) submitted for chemical ' analyses were reported by the laboratory to contain detectable concentrations of TPH of 165 ppm and 35 ppm, respectively. The sample from Boring B4 at 35 feet bgs was reported as not containing TPH. The laboratory results are summarized in Table 3. ' Laboratory reports and chain-of-custody forms are included as Appendix D. ' BTEX/MTBE in Soil The samples collected from Boring B4 submitted for chemical analyses were reported by the laboratory as not containing detectable concentrations of MTBE. The samples from Boring B4 at 35 and 45 contained concentrations of benzene ranging from non-detect (ND) (B4-35) to 0.057 ppm (B4-45). Toluene was reported at ' concentrations ranging from ND (B4-35) to 0.014 ppm (B4-45). Ethylbenzene was reported at concentrations ranging from 0.002 ppm (B4-35) to 0.33 ppm (B4-45). Total xylenes ranged from 0.009 ppm (B4-35) to 1.1 ppm (B4-45). Laboratory reports and ' chain-of-custody forms are included as Appendix D. Groundwater TPH in Water The groundwater samples from MW-1 and MW-3 were reported by the laboratory to contain non-detectable concentrations of TPH-g. The samples collected from MW-2 and MW-4 were reported to contain TPH-g at concentrations of 3.4 and 1.6 ppm, respectively. The sample collected from MW-2 was reported to contain TPH (C8-C44+) at a concentration of 2.3 ppm. TPH was not reported in the other groundwater samples submitted for analyses. TPH-g concentrations in ' groundwater are presented in Figure 5. The laboratory results are summarized in Tables 4 and 5. Laboratory reports and chain-of-custody forms are included as Appendix D. ' BTEX in Water The groundwater samples from MWA and MW-3 were reported by the laboratory to ' contain non-detectable concentrations of BTEX and MTBE. The samples collected from MW-2 and MW-4 and submitted for analyses were reported by ' the laboratory to contain non-detectable concentrations of MTBE. The samples collected from MW-2 and MW-4 and submitted for analyses were reported by the laboratory to contain concentrations of benzene ranging from 1.2 parts per billion (ppb) (MW-2) to 11 ppb (MW-4), toluene at a concentration of 1.8 ppb (MW-2 and MW-4), ethylbenzene from ' 20 ppb (MW-4) to 110 (MW-2) and total xylenes at concentrations from 89.1 ppb (MW-4) to 235.5 ppb (MW-2), respectively. BTEX concentrations in groundwater are presented in Figure 5. The laboratory results are summarized in Tables 4 and 5.
