Groundwater Conditions <br /> Groundwater occurred at depths of about eight to eight and one-half feet below the <br /> surface (see Table 1). A northwesterly groundwater flow direction was plotted from the <br /> monitoring well data under a gradient of 0.003 (see Figure 1). Water levels in the wells <br /> declined since the previous quarter. The water levels and groundwater flow direction are <br /> consistent with those previously observed. <br /> Chemical Analysis <br /> Three groundwater samples were analyzed at a STL/Chromalab, Inc., a State certified <br /> analytical laboratory from the monitoring and domestic wells. These samples were tested <br /> for the following; Total Petroleum Hydrocarbons as Gasoline (TPHG) and Diesel <br /> (TPHD), Benzene (B), Toluene (T), Ethylbenzene (E) and Xylene (X), Methyl-tert-butyl- <br /> ether (MTBE) and fuel oxygenates, 1,2 Dichloroethane and Ethylene Dibromide using <br /> EPA Methods 3510/8015, 8020, 8240 and 8260. The analyses were run on a "normal" <br /> turnaround (five- to ten working days). The results are presented in Figure 2 and Table 2 <br /> and historic data in Tables 3 and 4 below. <br /> Table 2.

Highly degraded TPHD has <br /> been observed at MW-3 previously and has declined over four quarters of site monitoring, <br /> and was observed in the September 2002 sampling. Well MW-3 now shows that <br /> contaminants are not detected. <br /> Page 2 <br />
