Does Muscle Shoals Utility Board have drinking water violations?
Of the 12 most recent violations in EPA's records, 3 are health-based, and the most recent began in October 2022. The violations listed here began between September 1985 and October 2022.

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.
