How to get your Washington D.C. water tested for PFAS

EPA UCMR 5 tested 3 public water systems in Washington D.C. — but at the utility entry point, not your tap. Aging pipes and indoor plumbing can change what reaches your home, and private wells aren't covered by UCMR 5 at all. To find out what's actually in your water, test it with a certified lab.
