In recent years, officials on both sides of the U.S. Canadian border have raised the alarm about increasing levels of selenium and nitrate in the Elk River and rivers and lakes further downstream, including in Northwest Montana. In 2013, a University of Montana study found that the level of selenium and nitrate in the Elk River was 5,000 times higher than in the Flathead River. That same year, the British Columbia government ordered Teck to come up with a plan to address the issue. But six years later, the issue has yet to be resolved.
