The groundwater samples were contained in laboratory-supplied containers, and transported in <br /> an iced cooler with chain-of-custody documentation to Kiff Analytical, LLC (Kiff), a state of <br /> California certified analytical laboratory (#2236) Kiff analyzed the groundwater samples for <br /> TPH-as-gasoline, benzene, toluene, ethylbenzene, xylenes (BTEX), MTBE, di-isopropyl ether <br /> (DIPE), ethyl-t-butyl ether (ETBE), tent-amyl methyl ether (TAME), tert-butanol (TBA) and 1,2- <br /> DCA by EPA Method 82608 <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 five of <br /> the eight monitoring wells sampled, at a maximum concentration of 210 µgll at MW-5 1,2-DCA <br /> was also detected in five of the eight monitoring wells sampled, at a maximum concentration of <br /> 19 µg11 at MW-5 Groundwater from Irrigation Well#2 did not contain detectable concentrations <br /> of any of the gasoline compounds The cumulative analytical results are summarized in Table 2, <br /> and the laboratory reports and chain-of-custody document are included as Appendix A <br /> i <br /> I <br /> 1 6 <br /> r <br />
