Alberta's plan to allow for open-pit coal mining in the Rocky Mountains could be a serious threat to Saskatchewan's water supply, says the director of the Global Water Futures Project at the University of Saskatchewan. "For a water scientist to see this happening, it's just an abomination to have these types of developments suggested in the headwaters of the rivers that supply drinking water and the economy for most of Saskatchewan," John Pomeroy told CBC's Blue Sky. Last spring, the Alberta government revoked a 1976 policy that blocked open-pit coal mining on the eastern slopes and peaks of the Rockies.
