SUMMARY AND CONCLUSIONS <br /> The following conclusions were drawn from the results of this investigation <br /> At the time of the November 2005 sampling event, depths to ground water ranged from <br />' 36 51 feet to 39 94feet below the tops of the well casings Ground water elevation at the site <br /> averaged approximately 6 10 feet above MSL,indicating an increase in average ground water <br /> elevation of approximately 0 21 feet since the last monitoring event in August 2005 <br /> - Ground water flow was inferred to be flowing toward the southwest under a hydraulic <br /> • gradient of approximately 0 004 foot/foot(ft/ft) This flow direction remains consistent with <br /> Advanced GeoEnvironmental,Inc <br /> 1 <br />
