I'll give you my point. Then Jason can likely add to it.
At the municipal level, it's certainly being looked at. However, from a cost perspective, it becomes overwhelming.
For PFAS, as an example, the investment to do this at a municipal level would be very large in terms of the resins alone. I was just watching a webinar today in which they were proposing some technology for putting a PFAS meter on people's taps, so they could watch and see whether they have PFAS coming into their home. That technology has to be built—maybe this is a perfect opportunity for Ms. Gomez—but I think it's easier, quicker and perhaps faster to address it in the home right now. We want to make sure the health of Canadians is looked after.
Jason, do you have anything?
