Massive toxic spill in British Columbia pollutes streams and lakes. The Mount Polley Mine mines copper and gold. These mines require massive amounts of toxic acids to “eat” the rocks that contain the copper and gold. The waste is “contained” in a big retention pond (in this case a huge lake). The ponds just sit there with no plans for clean up. Humans are banned from the ponds. Governments say they are safe (despite that ponds fail on average of 30%).
Millions of tons of harmful metals, soils, and wastewater spilled into pristine habitat. Canada’s response? Whooppsy! ¯\_(ツ)_/¯.

An earthen dam at Mount Polley Mine in British Columbia breached on August 4, 2014, sending contaminated water surging into nearby lakes. Wastewater and metal-laden sand spilled from a retention basin and triggered a water-use ban in Likely, British Columbia, and other nearby towns. Local authorities had lifted the ban as of August 12.
On August 5, nearly all of the wastewater in the retention basin had drained, exposing the silty bottom. Hazeltine Creek, normally about 1 meter (3 feet) wide, swelled to a width of 150 meters (490 feet) as a result of the spill. In the aftermath of the flood, a layer of brown sediment coated forests and stream valleys affected by the spill. Notice how much forest immediately north of the retention basin was leveled. Debris, mainly downed trees, are visible floating on Quesnel Lake.
