Title: The Mount Polley Mine Disaster: An Ecotoxicological Perspective
Speakers: Dr. Greg Pyle (University of Lethbridge)
Date: Thursday, April 15, 2021
Time: 10:00 a.m. PDT
On August 4, 2014, a tailings dam failed at the Mount Polley copper and gold mine in the Cariboo region of BC and spilled 25 M cubic metres of contaminated tailings into nearby aquatic ecosystems, including Quesnel Lake—the deepest fjord lake in the world, and the fifth largest lake in BC. The work of Dr. Pyle and collaborators examines the disaster from an aquatic ecotoxicological perspective.
