41st British Columbia Mine Reclamation Symposium 17-20 September, Williams Lake, BC, 2018

In 2005, the Crown Contaminated Sites Program began assessing on-site wastes, equipment, and other materials at the historic Bralorne-Takla mercury mine. Investigations confirmed the presence of unacceptable risks to human health and ecological receptors. Remedial objectives were identified to return the mine site to forest ecosystem. Remediation included capping mine openings, demolishing structures, disposing of hazardous waste off-site, consolidating non-hazardous waste in 2 on-site landfills, revegetating, and implementing administrative risk controls to protect future site users. The cover design included innovative elements to support forest growth. Selection of native species for seed mix, shrub and tree replanting focused on returning the mine site to a forest ecosystem and supporting traditional use of the land. Monitoring covers, drainage systems, landfill gases, water quality, vegetation performance, and land use risk controls are ongoing. Additional monitoring includes ambient mercury vapor monitoring and biomonitoring.
