Table 1. Groundwater Well Water Levels,March 2004 Date Depth to Well Casing Groundwater Comments Water(ft) Depth(ft) Elevation(msl Elev.(ft) ft MW-1 12/15/03 Not 20.97 45.09 -- None measured MW-2 12/15/03 Not 25.05 45.41 — None measured MW-3 12/15/03 8.03 24.81 46.01 37.98 None Groundwater Conditions Groundwater occurred in MW-3 at a depth of about eight feet below the surface (see Table 1). Since only one well was measured, a groundwater contour map was not prepared. The historic groundwater flow direction is north northwesterly (see Figure 1). Water levels in the well declined slightly since the previous quarter in this well. Chemical Analysis One groundwater sample was analyzed at STL/Chromalab, Inc., a State certified analytical laboratory from the monitoring and domestic wells. The sample was tested for the following; Total Petroleum Hydrocarbons as Gasoline (TPHG) and Diesel (TPHD), Benzene (B), Toluene (T), Ethylbenzene (E) and Xylene (X), Methyl-tert-butyl-ether (MTBE) and fuel oxygenates, 1,2 Dichloroethane and Ethylene Dibromide using EPA Methods 3510/8015, 8020, 8240 and 8260. The analyses were run on a "normal" turnaround (five- to ten working days). The results are presented in Figure 2 and Table 2 and historic data in Tables 3 and 4 below. Table 2.
