PFAS checker · published city records

Do public records report PFAS in your water?

Enter a city to locate its published report and inspect PFOA, PFOS and PFHxS findings. A city result is a starting point, not confirmation of the supplier or water at a specific tap.

What this checker can sayIt can show reported findings, non-detects and monitoring gaps. It cannot turn missing data into “PFAS-free” or issue a household safety verdict.

Or read your own lab result

How the checker works

Four steps, in order

1. Location
  Match the city to a published PurityMap report.
2. Public record
  Read only the PFAS entries supplied by that report.
1. Evidence state
  Keep detects, non-detects and missing monitoring distinct.
2. Next action
  Review treatment requirements and certification claims.

If a PFAS concern is confirmed

A public record is not a tap test.

Distribution conditions and household plumbing can differ from system sampling. When a household decision depends on the result, use a qualified laboratory and keep the reporting limit with the result.
