Sure. Thank you for that.
I think one of the biggest things, obviously, is that we, as an association, quite often try to work on that cross-boundary with other associations, but similarly right now we're waiting to hear what level of PFAS is going to be acceptable for us to treat in Canada. They've had it in the States, and they've even lowered it there. It is also very prevalent where it's been given a limit in Europe and things like that, but we seem to be sort of lagging behind when it comes to having that emerging contaminant quantified for us within Canada.
