It's a good question. I know that you've had presentations from and discussions with the federal and provincial people. The geology is a critical part of the hydrogeology, and the Geological Survey and the Alberta Geological Survey and Alberta Environment do all those things together. You're quite right that they have to be combined in a useful manner.
Most of my work is on lease, and the companies then have a large amount of information on lease. The geology and the hydrogeology is reasonably well understood on lease. The broader picture, which I think you were addressing, is clearly less understood. The mapping in the area, as I'm sure you've heard, is really just ramping up geologically and hydrogeologically. I believe that Alberta Environment has commissioned a study of the groundwater resources as they sit now. And the Alberta Geological Survey, I presume with the aid of the federal Geological Survey, is working on mapping these areas. Where they have mapped south of Fort McMurray, the maps are very useful, and it's a job well done. I'm not sure what percentage of the critical area is mapped, but it's certainly not 25%. So that's an ongoing activity.
The information on lease is quite good. Off lease is far less good and is very localized.
