Selenium pollution from Canadian coal mines is contaminating waterways across Montana and Idaho, raising concerns about the health of the transboundary Columbia River system.
Amanda Eggert reports for Montana Free Press.
In short:
- A U.S. Geological Survey study shows that selenium from British Columbia coal mines is polluting waters over 350 miles downstream, affecting Montana and Idaho.
- Despite investments in water treatment, selenium levels continue to rise, endangering fish populations with deformities and reproduction issues.
- Environmental groups call for stricter regulations and larger reclamation bonds to protect the ecosystems from further damage.

“Prompt and adequate action is needed to prevent further degradation of the health of the beautiful and diverse Kootenai ecosystem.”

Why this matters:
Selenium contamination threatens critical aquatic habitats and fish populations in the Columbia River basin, risking long-term environmental damage if not addressed. This issue underscores the need for stronger international cooperation and regulatory action to protect shared waterways.
