Is Your Tap Water Safe?

This past summer I wrote a post about PFAS chemicals in farm produce.  The source of the chemicals was from ground water that had been contaminated from firefighter foam used primarily on military bases.  At the time, the contaminated ground water seemed relatively contained to areas in close proximity to military bases.  Now, EWG has updated their database and it shows PFAS contamination of tap water in almost 1400 sites in 49 states.
