Reclamation Feasibility Report - Virginia Canyon <br />• <br />• <br />Historic Structures <br />There are no historic structures or artifacts at this site. <br />Water Quality Impacts <br />Waste Pile #66 is eroded by run-on water from the slope above. Waste rock from site #189 is <br />principally eroded by road drainage. In addition, the waste rock at site #189 is located in an <br />ephemeral drainage. There is probably some leaching of the waste rock at site #189 during wet <br />periods. Berms have been place along the edge of the road to control erosion, but these berms <br />have been observed to occasionally breach during thunderstorms. <br />The waste rock at site #66 had high leachable cadmium and zinc, and had the highest <br />concentrations of cadmium and zinc of all the waste piles sampled in the total metals analysis. <br />Waste rock is eroded from site #66 onto the road. Deep gullies have been cut in the waste rock at <br />site #189. Results from the 2:1 leachate analysis are given below: <br />cc+c AAA <br />• <br />pH <br />s.u.
