Legal Doesn't Mean Safe

  • Meeting legal standards doesn't always equate to safety. A passing grade from federal authorities doesn't necessarily signify that the water aligns with the latest health guidelines.


  • It's been nearly two decades since the permissible levels of contaminants detected in tap water were last updated.


  • The most reliable method for ensuring clean tap water is by preventing pollution from entering the source water in the first place.
