Choke point for oil sands may be water shortage

The amount of water available in Northern Alberta isn’t sufficient to accommodate both the needs of burgeoning oil sands development and preserve the Athabasca River, contends a study issued jointly yesterday by the University of Toronto and the University of Alberta.

The study, written in part by Dr. David Schindler, a University of Alberta biologist considered Canada’s top water expert, suggests that the choke point for the province’s oil sands expansion may not be the huge carbon dioxide emissions arising from mining and processing the sticky, bitumen containing tar sands, as is widely assumed, but a lack of water.
