SUMMARY AND CONCLUSIONS <br /> Based on the findings from this investigation, AGE concludes <br /> • Ground water at the site for the July 2003 rnonitoring event was inferred to be flowing <br /> toward the southwest at an average gradient of 0 0008 ft/ft The inferred ground water <br /> direction was nearly 180° from the direction of the March 2003 monitoring event The <br /> average ground water elevation at the site decreased approximately 3 36 feet since the March <br /> 2003 monitoring event <br /> I Ground water at the site for the December 2003 monitoring event was inferred to be flowing <br /> toward the northeast at an average gradient of 0 0007 ft./ft The inferred ground water <br /> direction was approximately 180° from the direction of the July 2003 monitoring event,but <br />' similar to the direction from the March 2003 monitoring event The average ground water <br /> elevation at the site decreased approximately 0 33 feet since the July 2003 monitoring event <br /> • Petroleum hydrocarbon-impacted ground water appears to be limited to the area near <br /> monitoring well MW-1 None of the target analytes were detected in samples collected from <br /> MW-2, MW-3, MW-4 and DW-1 <br /> IAdvanced GeoEnvironmental,Inc <br /> I <br />
