After identifying elevated metal concentrations in two seepages from a waste rock pile at Mount Polley Mine, an investigation was launched to determine the potential source as well as the implications for potential treatment. Evidence points to a previously unidentified source of acid mobilizing metals from the waste rock pile and being neutralized along the way, before daylighting at the base of the pile. The most likely source that was identified was a sulphur pile, which was stockpiled on site as a source of acid for leach pad research.

The August 2014 tailings dam breach at the Mount Polley Mine, BC severely disturbed downstream forest ecosystems through erosion and tailings deposition. The impacted area presents an opportunity to research using ecosystem legacies (components that survive a disturbance) to rehabilitate disturbed sites.

The Mount Polley tailings impoundment failure released 24 million m3 of mine-influenced water and sediment into the surrounding watershed. The scale of this spill is unprecedented in BC history, and the effects on current and future ecosystems are unknown. Of paramount concern is the containment of toxic metal-containing compounds that threaten aquatic life. My research addresses the role of wetlands and riparian soils in remediation of this spill. I established permanent monitoring sites under a Mitacs Accelerate award to track the progression of contaminants throughout the watershed.
