A Canadian mining company is responsible for selenium pollution entering North Idaho waters. Teck Resources is a mining company in British Columbia. Waste rock from four of their mines have been leaching selenium into the Kootenai River Watershed since the early 1980s. Selenium is toxic at high levels. Since 2017, the population of westslope cutthroat trout in this watershed has decreased by 93% because of selenium pollution.
As mining waste leaches into B.C. waters, experts worry new rules will be too little, too late
Teck Coal was ordered to pay a record $60 million fine this year for polluting waterways in the Elk Valley, but despite the penalty, contaminants continue to leach from piles of waste rock at the company’s mines — and the clock is ticking on new federal regulations that observers say are long overdue. “Leadership is desperately needed in this watershed from the Canadian federal government,” said Erin Sexton, a University of Montana biologist.
Alberta’s ‘back door’ plan to free up billions of litres of water for coal mines raises alarm
In Alberta, water users are granted the right to withdraw water from rivers and streams through a licensing system. In some watersheds, including the Oldman, that system is closed. There’s a finite amount of water available, and all of the licences are spoken for. The issue is not new. A water policy directive created by the Alberta government in 2006 found “limits for water allocations had been reached or exceeded on the Bow, Oldman and South Saskatchewan River sub-basins, putting at risk Alberta’s obligation to provide water to neighbouring provinces and conserve the aquatic ecosystem.”
Contaminant from coal mines already high in some Alberta rivers: unreported data
The province's plan for large-scale expansion of the industry is fueling widespread criticism that includes concerns over selenium pollution. The data shows that same contaminant has been found for years at high levels downstream of three mines and never publicly reported. The findings raise questions about Alberta Environment, said a former senior official who has seen the data. "There were lots of [selenium] numbers and it was consistently above the water quality guidelines and in many cases way higher," said Bill Donahue, the department's one-time executive director of science. "Why did Alberta Environment sit on these data for easily the last 10 to 15 years?"
