ti, w <br /> • <br /> Groundwater Conditions <br /> Groundwater occurred at depths of about 41 to 42 feet below the surface (see Table 1) A <br /> east southeasterly groundwater flow direction was plotted from the monitoring well data <br /> under a gradient of 0 0013 (see Table I and Figure 1). <br /> Chemical Analysis <br /> Seven groundwater samples were analyzed at Kiff Analytical, LLC, a State certified <br /> analytical laboratory These samples were tested for the following, Total Petroleum <br /> Hydrocarbons as Gasoline (TPHG) and Diesel (TPHD), Benzene (B), Toluene (T), <br /> Ethylbenzene (E) and Xylene (X), Methyl-tert-butyl-ether (MTBE) and fuel oxygenates, <br /> 1,2 Dichloroethane and Ethylene Dibromide using EPA Methods 3510/8015, 8020, 8240 <br /> and 8260 The analyses were run on a "normal" turnaround (five- to ten working days) <br /> The results are tabulated and presented in Table 2. <br /> Discussion <br /> The sample results show that contaminants were observed in monitoring wells MW-2 and <br /> SMW-3 The other wells showed that contaminants were not detected <br /> Conclusions and Recommendations <br /> Wright has competed the quarterly monitoring for the Stefano's site The monitoring data <br /> - show that TPH contaminants are present m MW-2 and MW-3 Additional subsurface <br /> investigation by Ramage showed that the groundwater contaminants are present in deeper <br /> strata and appear to be moving off-site to the east Wright has completed a proposed <br /> workplan for PHS EHD regarding additional off-site assessment with monitoring well <br /> installation following Upon obtaining permits and access agreements for offsite locations <br /> and upon approval of PHS EHD, the assessment work will continue <br /> Wright recommends that the quarterly monitoring program for TPHG, TPHD and BTEX <br /> and MTBE and oxygenates continue and the existing monitoring wells are scheduled for <br /> sampled in the next quarter. <br /> i <br /> Page 2 <br /> K ` <br />
