Hydrogeochemical investigation of elevated geogenic uranium in a subarctic region

Northern Canada faces environmental changes from growing resource extraction and global warming, which make an understanding of baseline conditions critical. In the Dawson Range, Yukon, naturally elevated concentrations of uranium have recently been discovered in groundwater at levels that exceed federal water-quality guidelines. This region is also the focus of advanced mineral exploration and falls within traditional territories of several First Nations. Mining activities may enhance uranium mobilization through the generation of waste rock and tailings. Thawing of permafrost might cause a similar effect by altering hydrological and geochemical conditions in groundwater. This project’s goal is to understand and communicate the baseline controls on uranium mobilization in the Dawson Range through analyses of water and rock samples and involvement with local industry, First Nations, and government.
