Okay. So let me take it a step toward where Health Canada would become involved. Just so the committee is very clear, we heard testimony that the water used by the residents of Fort Chip is all surface water. They're not using groundwater; they're not drilling water wells or anything like that for human consumption in the area.
What can you tell us about the state of the water treatment facilities in all first nation communities downstream of the oil sands? Fort Chip is not the only one that's downstream. What do we know about the state of water treatment facilities throughout the entire basin?
