Water is one of the four areas we're looking to accelerate environmental performance on. Great advancements have been made in water usage.
Actually, in some of the leading practices in the operations that use wells, the in situ fresh water is just a small fraction of the water used. Generally what we're doing is taking the water from non-potable sources, from saline, which can't be used for humans. That's the water we're using for production of the steam to recover the oil.
Most of the fresh water used in our facilities is actually for the camps, to support the people who are there. That's a really important progression that we've made to that stage.
The second thing is, yes, recycling is extensive. A range of 80% to 90% of the water is recycled. We're continuing to advance intellectual property. Numerous patents are out there—which again gets to R and D and the innovation going on in this field in the oil sands, of worldwide recognition—to really tighten up that recycling and that use that much more.
