Does New Hampton Pws have drinking water violations?
EPA's records list 8 violations for this system; 3 are health-based, and the most recent began in October 2021. The violations listed here began between May 1992 and October 2021.

Resolved means at least one resolving action is on record: the system returned to compliance, the rule no longer applies, or no further action was needed.
