Canadian Coal Mine Ramps Up Efforts to Challenge Montana Water Quality Standard

Canadian Coal Mine Ramps Up Efforts to Challenge Montana Water Quality Standard

An entourage of Canadian coal mining executives pressed into the Lincoln County commissioners’ conference room last week to deliver promising news for Lake Koocanusa, the 80-mile long reservoir that straddles the U.S.-Canada border in Montana and British Columbia, and which has been at the center of both statewide and international efforts to reduce transboundary environmental pollution for more than a decade. “Selenium levels in the Koocanusa Reservoir are safe,” according to a PowerPoint slide summarizing a March 30 presentation by representatives of the global mining company Teck Resources, who made the trip to Libby to deliver the news in person.

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?"
