Does Oilton have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in January 2026. The violations listed here began between April 2025 and January 2026. By type: 11 monitoring and reporting and 1 monitoring. The contaminants or rules involved are Chlorine, Revised Total Coliform Rule, Lead and Copper Rule and 2,4-D. EPA lists 9 as resolved, 2 as archived and 1 as addressed. 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. 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. Addressed means the violation is not resolved or archived and is covered by formal enforcement.
