Does Pioneer Park have drinking water violations?
EPA's records list 6 violations for this system; none is health-based, and the most recent began in October 2025. The violations listed here began between October 2024 and October 2025. By type: 5 monitoring and 1 monitoring and reporting. The contaminant or rule involved most often is Revised Total Coliform Rule (5 of them). EPA lists 4 as archived, 1 as unaddressed and 1 as resolved. Archived means the violation was not marked resolved but is more than five years past the end of the noncompliance period, so it no longer counts toward current compliance status. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement. 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.
