Moved here from Michigan. Check out the PFAS situations in Rockford MI, the Huron River, and Oscoda MI if you like cringing and being pissed off. My old neighborhood in New Hudson, MI was sick with cancers, autoimmune disorders, and infertility. The EPA "safe" level for PFAS in drinking is currently 0.004 PPT. It was 70 PPT just a few years ago. Open water samples in the Huron River 1/2 mile from my old house were as high as 54,000 PPT.

One of the draws of Vermont for my family is that the drinking water is generally clean. Sure there are a few super fund sites, but they are generally small and contained. I've been told that Burlington's water system produces some of the cleanest drinking water in the state. I have not tracked down stats to verify or disprove this.

I ended up assembling a big 10-stage water filtering and reverse osmosis system that helped a lot. I do not feel like this level of protection is required in most Vermont communities, but a reverse osmosis system could provide some piece of mind. Under sink units run from like $80 to $500 depending on the features included and brand. Did you know you Vermont has an extensive water sampling system that spans the whole state? Most of the time, the latest reports are published for the public to see here:
