As Teck Resources hopes to expand its mountaintop-removal coal mining in British Columbia, water quality monitors in Canada and the United States warn the company’s existing mines already cause significant ecological damage. In 2019, the company’s research revealed that more than 90% of the cutthroat trout population had vanished in a 37-mile reach of the Upper Fording River near its mines around Sparwood, British Columbia. On March 26, Teck pleaded guilty to two counts of illegally discharging selenium and other pollutants into the watershed and paid a $60 million fine – the largest of its kind in Canadian history.
