Has my water system found PFAS?
This map shows water systems included in the EPA's PFAS testing records, as of May 16, 2024. It's based on boundaries developed by SimpleLab, a water-testing company. Points represent systems where the exact boundaries are not available.
Enter an address to locate the nearest water systems. Then click on a system to review its PFAS detections.
The EPA has defined limits for six types of PFAS. If a water utility met or exceeded these limits at least once, they’re listed in the “Pollutants at/over limit” column. Systems are split into five categories:
- Annual average over limit: 293 systems surpassed the limit for at least one of the six limited PFAS when an entire year’s test results were averaged. They may need to act to comply with the EPA’s new rule.
- PFAS detected at/over limit: 502 systems had at least one sample meet or exceed the new limits, but the annual average of all measurements stayed below the limit.
- PFAS detected below limit: 306 systems detected one of the six limited PFAS chemicals, but the measurements were all below the limit.
- Unregulated PFAS detected: 492 systems detected one of 23 other PFAS compounds that currently have no legally enforceable limits.
- No PFAS detected: 3,157 systems found no detectable amount of 29 types of PFAS in their water.
