You're aware of the big Canadian report on groundwater that was completed by Dr. Jim Bruce, who just testified here. He also documents in his study unanswered questions identified by the Alberta Research Council in 2007. There is a whole list of issues on unknowns about groundwater in that area in northern Alberta.
Dr. Rivera, I think you alluded to the fact that we know something about the geology in the area, but we don't specifically know about the aquifers. In order to make any determinations on whether or not either the in situ or the mining will have an impact, is it necessary to know about the specific aquifers and where they're located?
