SUMMARY AND CONCLUSIONS <br />' Based on data collected during the monitoring event, AGE concludes <br />' The general ground water flow direction for HU1/HU2 was towards the west-northwest <br /> during the second quarter and the ground water flow direction was calculated to be north or <br /> . northwest in the lower flaw units (HU3 to HU6) <br /> Advanced GeoEnvironmentai,Inc <br />
