SUMMARY AND CONCLUSIONS <br /> Based on the data collected from the site, AGE finds <br /> • Ground water flow at the site on 08 August 2003 was inferred to be generally toward the <br /> south at an average gradient of 0 01 feet/feet, which is consistent with the historical ground <br /> water flow direction at the site Ground water elevations at the site decreased in wells MW-5 <br /> through MW-7 an average of 1 6 feet since the second quarter 2003 monitoring event <br /> f • TPH-g, TPH-d,BTEX and fuel additives were not detected at or above Iaboratory reporting <br /> limits in the ground water sample collected from well MW-8 <br /> Advanced GcoEnvironmental,Inc <br /> I <br />
