The groundwater samples collected from all three of the groundwater monitoring wells contained <br /> detectable concentrations of petroleum hydrocarbons The groundwater sample collected from <br /> MW-1 contained 7,900 µg11 of TPH-as-diesel, 8,300 µg11 of TPH-as-gasoline, 20 µg11 of benzene, <br /> 1,000 µg11 of ethylbenzene, and 40 µg/l of xylenes The groundwater sample collected from MW-2 <br /> contained 2,200 µg11 of TPH-as-diesel, 800 µg11 of TPH-as-gasoline, and 0 81 µg11 of <br /> ethylbenzene The groundwater sample collected from MW-3 contained 11,000 µg11 of TPH-as- <br /> diesel, 2,900 µg11 of TPH-as-gasoline, 16 µg/l of benzene, 370 µg11 of ethylbenzene, and 23 µg11 of <br /> xylenes The gasoline oxygenate compounds and 1,2-DCA were not detected in any of the <br /> groundwater samples The groundwater monitoring well sample analytical results are <br /> summarized in Table 2 The concentrations of TPH-as-diesel, TPH-as-gasoline and benzene are <br /> posted on Figure 4 The laboratory report is included as Appendix A <br /> 9 <br />
