Assessment of Natural Copper-Nickel Bedrocks on Water Quality [Project]

Large deposits of copper, nickel, cobalt, and other minerals in northeastern Minnesota could provide huge economic and employment benefits to the state while becoming an important source of important metals for the country. However, the mining required to extract them could have significant water quality impacts in a region that includes the Boundary Water Canoe Area Wilderness and other environmentally sensitive watersheds. Up-to-date and accurate geochemical data is needed In order to assess and predict water quality impacts of potential mining and inform decision-making to protect water quality and sensitive ecosystems. Scientists at the University of Minnesota are using this appropriation to gather baseline data for assessing how existing concentrations of these metals in rocks, streambeds, and soils currently influence regional water quality. This information is a critical component for examining the risks posed by any potential future mining.
