Dr. Barker, in your brief summary you stated something that's very interesting to me. You stated that formerly, the big oil sands operations, Suncor and Syncrude, were able to site on impermeable material, but the new ones are being forced to site the tailings ponds on or near shallow aquifers with permeable land.
Would it be fair to suggest that it's probably really important to complete these studies to know what the risks are before we steamroll ahead with operations on lands that are permeable?
