Nobody knows? I find that mind-boggling.
I'm going to move on to another question.
Ms. Switucha, sorry to target you, and it's not targeting you; it's the system. On the sampling focus you mentioned, where you found 92% compliance, or only 8% sampling, I'm just questioning why you would sample at the leading end of the system.
It seems like you would be sampling the top end of a river system, where the water is quite pure, but when you look at the Fraser River, after it's passed municipal effluent, outflows, and so on, it's not so pure. If you started at the tail end, would you not be able to trace back to where the problems were much better than sampling at the top end, where it's actually quite pure still?
