14� <br /> Groundwater Contour Map and Flow Gradient <br /> A groundwater contour map to a known datum was prepared for the data listed in Table 1 above <br /> (see Figure 1) The groundwater flow direction was to the northerly under a calculated gradient <br /> of 0 0027 The flow direction is consistent with historic observed trends, and remains <br /> relatively flat Overall groundwater levels appear to have risen about 0 5 foot from the <br /> previous quarter <br /> Chemical Analytical Methods and Results <br /> Nine groundwater samples were analyzed using EPA Methods 503018015, 602 and 8260 f o r <br /> Total Petroleum Hydrocarbons as Gasoline (TPHG), Benzene, Toluene, Ethylbenzene and Xylene <br /> (BTEX) and fuel oxygenates including Methyl-tent-butyl-ether (MTBE), Tert-Butyl Alcohol <br /> (TBA), Di-Isopropyl Ether (DIPE), Ethyl tert-butyl ether (ETBE), Tert-Amyl Methyl Ether <br /> TAME), 1,2-Dichloroethane (1,2-DCA) and Ethylene Dibromide (EDB) The analytical results <br /> of the groundwater samples for this sampling event are attached and listed below in Table <br /> 1(historic data is presented in attached spreadsheet Table 2), <br /> Table 1.
