Contaminant from coal mines already high in some Alberta rivers: unreported data

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?"

River Talk — Movement grows to build weir/dam across Koocanusa Reservoir

River Talk — Movement grows to build weir/dam across Koocanusa Reservoir

Completed in 1973, the Army Corps of Engineers dam was designed to regulate how spring snow melt in the Kootenay River watershed (87% of which originates in Canada) enters the downstream watershed. It has done so effectively, but at a considerable price to local residents. The upper end of the reservoir in Canada bears the brunt of the storage draw down each spring, and in dry years, the reservoir’s moonscape does not always refill to a level that allows for much recreation. The control over these water levels is 100% vested in American operation of Libby dam.
