Overview
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.
AquaPura's analysis shows 10 contaminant(s) detected in Northwest Utility District-SD's water exceed recommended health guidelines, though they may be within legal limits set by the EPA.
