Three years of mining, 40 years of taxpayer clean up for river downstream of Vancouver Island copper mine

After an abandoned copper mine destroyed the Tsolum River in Canada, it took decades and cross-sector collaboration to reduce acid runoff and bring back fish populations. The government, a restoration society, and even the mining industry worked together to come up with solutions to save the river. Their latest attempt — capping the mine waste with glacial sediment and an asphalt covering — in 2009 succeeded. In 2015, 129,000 pink salmon came back to the river — a record return since fish counts began in 1953.
