Thank you, Chair.
Thank you to the witnesses for being with us today.
I saw Dr. Schindler in the back as I was sharing in questioning the witnesses in the first hour. I think Dr. Schindler heard me share that I had taken a tour by river of the oil sands a couple of years ago. In that tour we stopped along the shoreline, and I saw the bitumen leaching into the soil. This was, I think, probably in June. It wasn't a terribly warm day, but warm enough, of course, that the bitumen was leaching out of the rocks of the shoreline.
In the Athabasca region, what toxins do we see naturally occurring in the boreal wetlands feeding into the Athabasca? What toxins are we seeing naturally occurring as a baseline?
