Editorial interest 83/100 Selection signal · not a rating of the site

A searchable, city-level guide to U.S. tap-water records on fluoride, PFAS, lead, and violations.

Landing page captured for the 2026-10-25 issue.

For: U.S. residents checking local tap-water records
Worth noticing: The site says it matches utilities to places using service-area boundaries and census blocks, rather than relying on city limits.

Field notes

The homepage displays searchable city records, county maps for PFOA/PFOS and fluoridation, state summaries, and recent health-based violations. Its methodology describes combining EPA records for 49,342 community water systems, 1,265,267 violation records, and 1,991,977 PFAS test results with CDC fluoridation data. It says service-area boundaries and census blocks are used to connect places with utilities, and that figures are presented against legal limits without site-created ratings.
