Ecological impact of Mount Polley mine disaster confirmed by new study

A newly published scientific study confirms the deep ecological impact of the Mount Polley mine disaster in B.C.'s Cariboo region nearly eight years ago. The study, published last week in the academic journal Environmental Science and Pollution Research, shows small invertebrates taken from lake water affected by the tailings spill disaster had a higher concentration of copper and other metals than those taken from unaffected lake water.

Seven years after Canada's largest tailings spill, the two engineers who were involved have been found in breach of their professional codes of conduct. On Aug. 4, 2014, a four-square-kilometre tailings pond breached at Mount Polley mine in central British Columbia, leaking vast amounts of water and effluent into Polley and Quesnel lakes and Hazeltine Creek.
