Does Steeleville have drinking water violations?
Of the 12 most recent violations in EPA's records, 2 are health-based, and the most recent began in January 2026. The violations listed here began between October 2025 and January 2026. By type: 10 public notice, recordkeeping or other and 2 contaminant level above the legal limit. The contaminant or rule involved most often is Public Notice (10 of them). EPA lists 7 as unaddressed, 3 as resolved and 2 as archived. 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. 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.
