A breach in a tailings pond from the open-pit Mount Polley copper and gold mine sent five million cubic meters (1.3 billion gallons) of slurry gushing into Hazeltine Creek in B.C. That’s the equivalent of 2,000 Olympic swimming pools of waste, the CBC reports. Tailings ponds from mineral mines store a mix of water, chemicals and ground-up minerals left over from mining operations.
The flow of the mining waste, which can contain things like arsenic, mercury, and sulfur, uprooted trees on its way to the creek and forced a water ban for about 300 people who live in the region. That number could grow, as authorities determine just how far the waste has traveled. The cause of the breach is still unknown.
GR: Such a great waste of the land. Ecological succession, the natural process of recovery after a landslide or flood can take hundreds of years. However, the mined landscape looks almost as harsh as a lava flow. Humans could be long gone by the time nature reclaims the land. Oh Canada, what have you done?
