There's tons of things you can do.
What you should not bother doing is replacing your cooking pans because PFAS does not come from that. (Nor does it come from food storage containers or water bottles.)
The first thing to do is avoid paper dishes, no paper straws or any other kind of compostable dishware. The are frequently sprayed with PFAS to make them waterproof, and unless you are buying them yourself and checking you have no way to know what kind they are.
Avoid snowboarding - snowboards (and skis also I think) are sprayed with PFAS to make them slippery. The snow in the area will be covered in it, so just don't do that kind of sport.
Check your outdoor clothing, and kind of breathable clothing that is also waterproof is most likely coated with PFAS to make that happen. This is not just rain jackets, but also active-wear advertised as "quick drying".
Add a carbon filter (any kind) to your drinking water, you don't need reverse osmossis, carbon works fine. And helps for tons of other things you don't know are in there - plus it tastes better.
As a general rule any time you see an object that should get soaked with water stay dry be careful!
