Therefore, <br />all recrorded monitoring events are considered Operational. <br />Borehole B-8 is located below the West Ridge Waste Pile sedimentation pond and monitors subsurface <br />groundwater flow from the sedimentation pond. Borehole 8-8 is dry. <br />There is no baseline collection possible for points initiated after the influence of mining. <br />Ground Water <br />Figure No. 6 <br />
