The total amount of water is of the order of 12 to 13 barrels, as some of the publications suggest. Of that, about 80% to 90% is recycled. Syncrude, in their last sustainability report, published a figure of 88% recycled.
So if you take the 12 to 13 barrels and recycle 80% to 90% of that water, you will need some water to make up for what is still needed. That comes from the Athabasca River. It's about two to four and a half barrels.
