Ecological Risk Assessment of Copper within the Koala Watershed, Ekati Diamond Mine (BHP Billiton, October 2001)
1 October 2001Report
A screening-level ecological risk assessment of copper in the Koala Watershed at the Ekati Diamond Mine evaluating whether copper concentrations in water and sediments pose risks to aquatic organisms. The assessment concludes that four locations (Panda Diversion Channel, Kodiak Lake, Kodiak-Little Stream, and Little Lake) present low to negligible risk, with all other locations showing negligible risk of adverse ecological effects from copper exposure.
