I can start there, though I can't provide you with specific information on what occurred from pipeline leakage or fracture or issues in that respect. But again, it raises an interesting and important point that I intended to include in my brief, but I didn't want to give you guys a tome.
We use a concept called water footprint or virtual water in a lot of our work. Monsieur Ouellet, you alluded to it this morning when you talked about the water that's embedded in a barrel of oil. In fact, when you follow oil sands bitumen along its supply chain, you realize that in fact we're having impacts not only on the Athabasca River, but on others as well. As the bitumen moves to the North Saskatchewan River basin and Edmonton and Upgrader Alley, we're having impacts on the water use in that river basin. And then when we pipe that, as we're planning to, or are already doing, to the Great Lakes basin, we displace that issue to an area that I'm sure is as close to your heart as it is to mine.
So we're in fact having impacts along a number of watersheds, and the virtual water concept helps us to understand that. But it's an important point to recognize that when we start to extract this resource, by the time it gets to its end use—in fact, even before it gets to its end use, because we're still talking only about the products that come out of the refiners—we're in fact impacting a number of watersheds and a number of areas of important freshwater habitat and resources across the country.
