Thank you.
So the theory would be, then, that either things are getting through the filtered water or the people of Fort Chipewyan are drinking from the rivers, which Dr. David Schindler recommended not be done. They may also be ingesting natural foods or foods from the land that would be contaminated. That would be the transmission mechanism, I guess.
I recall Dr. Schindler saying if there are heavy metals in the sediments from the oil sands, chances are they would get caught way upstream and wouldn't make their way downstream. Have you heard that argument?
