As Teck Resources plans to distance itself from coal, government records show the mining giant remains a long way from solving the widespread contamination of local rivers and creeks — despite having already invested $1.2 billion in water treatment. Last year, selenium levels 267 times higher than what’s considered safe for aquatic life were detected in waters directly affected by Teck’s Elk Valley mines, according to an internal government meeting note obtained by The Narwhal through a freedom of information request.
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?"
