The Mount Polley Tailings Spill: Response and Recovery – 6 Years Later

Lecture Abstract


Six years after a glaciolacustrine layer under the tailings dam at the Mount Polley Mine failed, and 25 million cubic metres of water, tailings and embankment materials spilled into the surrounding environment, significant progress has been made in remediating the spill impacts. The company has invested on the order of $70 million on clean-up and repair. Human health and environmental impact and risk assessments, monitoring studies, and extensive remediation of impacted areas have been completed. Risk assessments indicate human health risks from the spill are low, while environmental impacts are low to moderate, with impacts primarily related to the homogeneous grain-size and low-organic content of the spilled tailings. The remediation response has therefore been focused on physical aspects of the spill. Ongoing monitoring indicates that impacted ecosystems continue showing positive signs of recovery. Communications with stakeholders and First Nations were maintained through regular community meetings, community newsletters, and site tours with regulators, First Nations, community representatives, and members of the local public.
