SUMMARY AND CONCLUSIONS <br /> Based on data collected on the site, AGE concludes <br /> • Depth to ground water at the site averaged approximately 29 45 feet bsg on 30 <br /> December 2004 <br />' Ground water elevation in the monitored area ranged from 17 36 feet to 19 00 feet below <br /> MSL Flow direction was inferred to be toward the east-northeast under a gradient of <br /> approximately 0 010 ft/ft <br /> • In well MW-1, TPH-g,BTEX and 1,2-DCA were detected with concentrations of benzene, <br /> ethylbenzene, and total xylenes significantly above the DHS's Maximum Contaminant <br />' Levels established for these compounds in drinking water <br /> • The extents of petroleum hydrocarbon and BTEX compounds at the site have not yet been <br /> defined <br /> 5.0. RECOMMENDATIONS <br /> Based on the findings recounted in this report, AGE recommends <br /> • Continued quarterly monitoring of the site, the next monitoring event should take place in <br /> March 2005 <br /> • Once the impacts to soil and ground water have been delineated, a work plan should be <br /> prepared for feasibility testing to evaluate various remedial alternatives at the site <br /> Advanced GeoEnvironmental,Inc <br />
