Does City of Rollingwood have drinking water violations?
EPA's records list 10 violations for this system; none is health-based, and the most recent began in December 2025. The violations listed here began between August 1993 and December 2025.

EPA lists 7 as resolved, 2 as archived and 1 as unaddressed. 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.

Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement.
