Contamination score

Higher = more contaminated vs. other cities.

The City of Adams shut down one of its two municipal drinking-water wells in May 2022 after sampling found PFAS ('forever chemicals') at levels the Wisconsin DNR and Dept. of Health Services considered a health concern, as reported by the Wisconsin Examiner and CBS News. This was part of a broader wave of PFAS well closures across central Wisconsin (including nearby Marshfield). The city has continued relying on its remaining well while addressing the contamination.
