We had taken almost 500 water samples in Quebec. That was probably the largest database on PFAS in drinking water in Canada. It was very valuable information that the people at Health Canada could have based their recommendations concerning PFAS on.
The recommendations do have to incorporate the effects of PFAS on health, but we have to come up with something that can be managed reasonably. It includes an element of management. We can't say that all Canadians' drinking water is no good and all water has to be treated. We have to do a cost assessment and see whether it is reasonable. The data show, based on what Health Canada proposed, that less than 5% of water systems had water that needed to be treated. It is complicated for the people in La Baie, for example, but these are very special cases. If we know the places where water poses a problem, we can manage that handful of cases.
