DISCUSSION AND CONCLUSIONS <br /> Based upon data collected from the site, AGE concludes <br /> Ground water elevation decreased approximately 3 6 feet at the site between the March 2001 , <br /> and the June 2001 monitoring events The inferred ground water flow direction is toward the <br /> northeast which is consistent with previous results The ground water gradient was 0 001 ft/ft <br /> • across the site <br /> Advanced GcoF,livironmental,Inc <br /> 1 _ , <br />
