It’s my second filter, my community still hasn’t tested for PFAS. I did with your test kit.

New River experience
Your kit is great, easy to follow instructions with everything needed included, even the return UPS sticker. The one suggestion is what the results mean for those contaminants that are highlighted but do not exceed the EPA safety levels. Does it mean that one drink of that water likely won't affect you but if you drink it daily over a period of years that may not be the case. It's just not clear what the results indicate for those contaminants that you highlight.

The service was excellent and the test results are quite useful. It would be good to know more about sources of information regarding PFAS in drinking water.
