  • Legal does not necessarily equal safe. Getting a passing grade from the federal government does not mean the water meets the latest health guidelines.
  • Legal limits for contaminants in tap water have not been updated in almost 20 years.
  • The best way to ensure clean tap water is to keep pollution out of source water in the first place.

PFAS Detected (UCMR-5 Update)

The Environmental Protection Agency in August 2023 released a set of public water system testing data for the “forever chemicals” known as PFAS, as required by its Fifth Unregulated Contaminant Monitoring Rule, or UCMR5. The EPA released the following results.
