Does Zumbro Falls have drinking water violations?
EPA's records list 11 violations for this system; 2 are health-based, and the most recent began in January 2024. The violations listed here began between April 1991 and January 2024. By type: 7 monitoring and reporting, 2 monitoring and 2 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (6 of them). EPA lists 8 as resolved and 3 as archived. 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.
