i <br /> i <br /> At two of the CPT locations, MTBE was detected in groundwater-bearing zones beneath the <br /> groundwater table At CPT-4, the groundwater sample collected at 66 feet contained 86 µg11 of <br /> MTBE, and the groundwater sample collected at 78 feet contained 1,100 µg11 of MTBE and 34 <br /> µg/l of TBA At CPT-2, the groundwater sample collected at 58 feet only contained 0 59 µg11 of <br /> ' MTBE These groundwater sample results are summarized in Table 6 The laboratory report is <br /> included to Appendix F <br /> ' The groundwater samples collected from all four of the groundwater table monitoring wells <br /> contained detectable concentrations of gasoline constituent compounds The groundwater <br /> sample collected from MW-2 contained 330 µg/l of TPH-as-gasoline, 0 84 µg/l of benzene, 0 66 <br /> p.g/l of toluene, 1 3 µg/I of ethylbenzene, 2 8 µg/l of xylenes, 160 µg11 of MTBE and 19 µg/l of TBA <br /> At MW-4, only MTBE (2,800 p.g/l) and TAME (3 2 pg/1) were detected The groundwater sample <br /> collected from MW-1 only contained 0 9 µg/l of benzene, and the sample collected from MW-3 <br /> ' only contained 3 8 µg/l of MTBE The groundwater monitoring well sample analytical results are <br /> summarized in Table 7 The distribution of MTBE at the groundwater table is shown on an <br /> isoconcentration map (Figure 5) The laboratory report is included in Appendix F <br /> Gasoline constituent compounds were not detected in any of the domestic water wells sampled <br /> These analytical results are summarized in Table 8, and the laboratory report is also included in <br /> Appendix F <br /> i <br /> i <br /> 14 <br /> I <br /> I <br />
