Videos and the homeowner side

 

Short video explainers of these papers are on the Safe Home Drink YouTube channel, including Five Open Studies on Safe Drinking Water at Home and Why New Homes Should Come With a Drinking-Water Line.

For homeowners, the same research is turned into plain, sourced guides at safehomedrink.com: how to read your water report, which filter certification matters, and what PFAS claims on filter boxes really cover.
