A subsurface investigation was undertook around the perimeter of Basin F. The purpose of the investigation was two-fold to delineate the ground water contamination levels around the reservoir and identify potential areas for leakage out of the basin, and to delineate the subsurface conditions around the basin as a first step to aid in the design for a full-depth containment system around the basin. Conclusion drawn in this report include The bedrock surface underneath the basin is at more shallow depths than previously thought and in some places has the capability to transmit water. Ground water flows underneath Basin F in a generally northward direction and a ground water divide occurs on the North side of the reservoir. There is a hydraulic connection between the near surface aquifer and a permeable bedrock sediment. On the basis of ground water gradients and water quality determinations, there are four to five leakage points around the basin.
