Welcome, everyone, to this more or less first formal hearing as part of our trip out west to study the oil sands and their impact on water.
I'd like to welcome our first two witnesses, Dr. Selma Guigard, who's an associate professor in the environmental engineering program at the University of Alberta; and Dr. Murray Gray, who is a professor at the University of Alberta.
We'll start with a ten-minute presentation from each witness, and then we'll proceed to our usual round of questioning.
Who would like to go first?
