Failure of Water Treatment Plant at B.C. Coal Mine Raises Downstream Concerns – by Tristan Scott (Flathead Beacon – June 20, 2017)

As British Columbia’s downstream neighbour, Montana has long been concerned about mining pollution spilling across the international border and into its world-class watersheds — fears that a growing body of research and evidence confirms are well founded.

Most recently, conservation groups and scientists on both sides of the border have renewed their calls for Teck Resources to halt new coal mines in the Elk River Valley, a step they say gained urgency when an experimental water treatment facility designed to stem the flow of a mining contaminant called selenium was taken offline because it was releasing an even more biologically toxic form of the heavy metal.

The trouble brewing in the Elk River is equally worrisome for Montana, where the upstream waterways of British Columbia flow into two shared bodies of water straddling the international boundary — Lake Koocanusa and the Kootenai River.

A spokesperson for Teck, the Vancouver-based global mining giant that operates five steelmaking coal mines just across the border from Montana, acknowledged the problem at the company’s water treatment plant and said efforts are underway to correct it.

“We are working to address a challenge related to selenium compounds at our West Line Creek Active Water Treatment Facility,” according to a statement. “We have a dedicated team working on this issue and have identified a corrective option that is now undergoing pilot-scale testing at the facility. We are also conducting ongoing, extensive aquatic monitoring. It’s not believed that this selenium compound issues poses any immediate risk to aquatic or human health.”
