Analysis of Water Quality Impacts at the Buckhorn Mountain Mine and Recommendations for Improvement
This report (PDF, 1 MB) responds to contaminant increases that triggered adaptive management in Gold Bowl Creek. The increases are more extensive than previously reported. The report provides an overview of important events at the mine, violations and orders submitted by Ecology, information on water quality standards and exceedences that have occurred but were not noted by Kinross or Ecology, and adverse environmental effects that have occurred and their current status. The report proposes recommendations for actions that could be taken by Kinross to increase environmental protection.
The use of reverse osmosis improved the water treatment facility and lowered some contaminants downstream from the discharge points, but others related to blasting have been decreasing more slowly.
