i <br /> ' The groundwater samples were contained in laboratory-supplied containers, labeled, and <br /> transported in an iced cooler with chain-of-custody documentation to Kiff Analytical, LLC (Kiff), a <br /> state of California certified analytical laboratory (#2236) <br /> Kiff analyzed the groundwater samples for TPH-as-gasoline, benzene toluene, ethylbenzene, <br /> ' xylenes (BTEX), MTBE, di-isopropyl ether (DIPE), ethyl-t-butyl ether (ETBE), tert-amyl methyl <br /> ether (TAME), tert-butanol (TBA) and 1,2-DCA by EPA Method 8260B The laboratory reports <br /> and chain-of-custody document are included as Appendix A <br /> Analytical results of the groundwater samples indicate that dissolved concentrations of gasoline <br /> hydrocarbons continue to exist in groundwater beneath the site TPH-as-gasoline and the BTEX <br /> compounds were not detected in any of the groundwater samples MTBE was detected in six of <br /> the ten monitoring wells sampled, at a maximum concentration of 400 µg11 at MW-7 1,2-DCA <br /> was also detected in six of the ten monitoring wells sampled, at a maximum concentration of 27 <br /> µg11 at MW-7 Groundwater from Irrigation Well #2 did not contain detectable concentrations of <br /> any of the gasoline compounds analyzed The cumulative analytical results are summarized in <br /> Table 2 <br /> i <br /> 1 0 <br /> r <br /> 6 <br /> r <br />
