Showing 3 of 3 cities · scores are system-level, not tap tests

Ranked by the Purity Score of each city's main water system, highest first. Scores belong to water systems; there is no county score. The score is computed only from contaminants measured in the published EPA record, so this ranks the record, not which city's water is safest. How the score works.

The ranking compares the records, not which city's water is safest, and your own tap can differ with household plumbing.

How many Outagamie County cities had a PFAS sample above a 2024 EPA limit?

None of the 3 Outagamie County city reports had a PFAS sample above a 2024 EPA limit in EPA's UCMR 5 testing. PFAS were detected below the limit in 1.

Is there lead in Outagamie County tap water?
