Mount Polley disaster's toxic impact continues to filter through B.C. waters, 10 years later: researchers

Contents from an Imperial Metals tailings pond are pictured going down the Hazeltine Creek into Quesnel Lake near the town of Likely, B.C. on August, 5, 2014, following the collapse of the Mount Polley mine tailings dam.

The catastrophic collapse of a tailings dam sent about 25 million cubic metres of poisoned water from the Mount Polley copper and gold mine surging into waterways on Aug. 4, 2014. The environmental impacts are still being felt, scientists fear, with toxic particles swirling in Quesnel Lake's water a decade later.
