Massive Spill at Canadian Gold Mine Detected By Satellite
On Aug. 4, an approximately 580 acre impoundment failed at a Canadian gold and copper mine near Likely, British Columbia. The breach at Imperial Metal's Mt. Polley mine dumped an estimated 1.3 billion gallons of toxic mine waste into the surrounding environment. On Aug. 5, Landsat 8 acquired an image of the mine showing that grey sludge from the tailings dam has entered Polley Lake, saturated the entire length of Hazeltine Creek and entered Quesnel Lake more than five miles downstream of the failed impoundment.

The spill has prompted drinking water bans throughout the region, since the pond contains a slurry laden with arsenic, lead, mercury, selenium and other toxic metals and compounds.

The president of Imperial Metals, Brian Kynoch, claims that the water in the tailings pond is "near drinking water quality" and expressed disbelief that the impoundment could fail so catastrophically, despite the fact that Canadian officials had issued multiple warnings to Imperial Metals for exceeding water quality standards for effluent and exceeding the permitted wastewater levels in the pond.
Local citizens anticipating the arrival of a salmon run now fear the worst for the environment and tourism, especially as they begin to document dead fish in Quesnel Lake.
Environmental groups across North America will be watching this story closely given the similarities to the proposed Pebble Mine in Alaska's Bristol Bay watershed, the world's most productive wild salmon fishery. Tailings ponds at Pebble mine would cover a surface area 13 times larger than the Mt. Polley impoundment and would have similar earthen dams taller than the Washington Monument.

Torrents of wastewater flow daily from the nation's 1.5 million active oil and gas wells and the agency's own research has warned it may pose risks to the country's drinking water supplies.
