SUMMARY AND CONCLUSIONS <br />' Based upon data collected from the site, AGE concludes <br /> • The ground water gradient was calculated to be 0 001 ft/ft directed towards the northeast <br />' Depths to ground water ranged from 80 71 feet to 81 10 feet bsg for an average of 80 96 feet <br /> bsg Depth to ground water increased an average of 0 36 feet since the previous monitoring <br /> event in September 2005 Ground water elevations at the site ranged from 23 96 feet <br /> • (MW- to 24 10 feet (MW-3)below mean sea level <br /> There were no constituents of concern reported in the ground water or domestic well <br />' samples <br /> 5.0. RECOMMENDATIONS <br />' Based on the findings of the environmental activities recounted In this report, AGE recommends <br /> • Continued quarterly monitoring of the on-site ground water monitoring wells and domestic <br />' well The next monitoring event should be performed in February 2006 <br /> • If the first quarter 2006 ground water monitoring event reports continued non-detection <br />' levels of constituents of concern, then the site should be prepared for closure and a No <br /> Further Action determination made <br /> I <br /> i <br /> Advanced t;eolanvironmental,Inc <br /> I <br />
