What we can help with

• A number looks wrong. Send the page address and what you believe is correct. Our corrections policy explains what happens next.
• Your city shows the wrong water system. Tell us your ZIP code and the name on your water bill.
• Press and research. You're welcome to cite any page. The national PFAS report and each state report include a suggested citation and a CSV download.
• Utilities. If your system's results changed, the update appears after EPA's next quarterly release. We'll add a note to the page in the meantime.

What we can't help with

We can't give medical advice or interpret a home test for you. Your state drinking water program or local health department can. You can compare a lab report with the federal limits yourself using Check your test results.

Is the water unsafe right now, or did you get a boil-water notice? Follow your utility's instructions first. What each type of notice means.
