My concern would be that most of the fresh water that we have on the planet is in groundwater. It's not in lakes and it's not in rivers and it's not in the ice caps. It's right in the ground. Once you contaminate an aquifer, it becomes virtually impossible to clean it up.
It would seem to me that we should be testing the aquifers. And if it is the case that this aquifer has been contaminated, then it can be kissed off, because there's going to be no rehabilitation for many centuries. But at the very least, use that water, and be very careful before you do any tailings ponds that don't take into account what the aquifers are doing and what activity is there. It staggers the mind.
I come from the Waterloo region, and we're very much dependent on groundwater there. I know that if you contaminate a deep aquifer, that's it, there's no rehabilitation for it.
Can we have some kind of testing in terms of monitoring what's happening there now? We'd want to know it for the sake of science anyway.
