Chemical Analytical Methods and Results <br /> Three groundwater samples were analyzed using EPA Methods 5030/8015, 602 and 8260 f or <br /> Total Petroleum Hydrocarbons as Gasoline (TPHG), Benzene, Toluene, Ethylbenzene and Xylene <br /> (BTEX) and fuel oxygenates including Methyl-tert-butyl-ether (MTBE) The analytical results <br /> of the groundwater samples are attached and listed below (see Table 2), <br /> Table 2.
