Why Search Water Quality by ZIP Code?
Localized Contamination Risks
Water quality varies dramatically by location. ZIP code searches reveal contamination specific to your neighborhood, including PFAS from nearby military bases, lead from local infrastructure, or agricultural runoff affecting rural areas.
EPA Doesn't Regulate Everything
The EPA only sets legal limits for 90 contaminants, but over 300 pollutants can be present in drinking water. Many utilities test for additional contaminants—our ZIP code tool shows what's actually in your water, not just what's legally required.

Once you know what's in your water, you can take action. Our platform connects you with:
- •NSF-certified filters proven to remove specific contaminants
