The data to understand PFAS contamination in your community exists. It's just not accessible to the people who need it most.
The EPA, USGS, and state agencies collect extensive PFAS contamination data. But it lives in technical databases, uses specialized terminology, and requires tools most people simply don't have. A parent trying to understand whether their tap water is safe shouldn't need a data science background.
PFASData.com aggregates, normalizes, and presents that data in plain language — with clear sourcing, honest coverage disclosures, and no agenda beyond public information.
We are not a testing service, not affiliated with any regulatory agency, and we don't sell data, advertising, or water filters. When you search your zip code here, you're getting government data presented clearly — nothing more, nothing less.
A note on water utilities: finding PFAS in your water system's data does not mean your utility caused the problem. In the vast majority of cases, utilities are working to treat water contaminated by industrial or military sources upstream — often chemicals discharged into the environment years or decades before current regulations existed. The utilities now bear the cost of detecting and removing chemicals they did not put there.

PFAS health effects are an active area of research and regulatory change — thresholds and recommendations evolve. Always consult your water utility, state health department, or a qualified professional before making decisions about your water supply.
All data is linked to its original government source. We encourage verification against those primary sources before making health or legal decisions.
