Does Elsberry Pws have drinking water violations?
EPA's records list 9 violations for this system; 3 are health-based, and the most recent began in March 2026. The violations listed here began between August 1993 and March 2026. By type: 5 monitoring and reporting, 2 required treatment not met, 1 reporting and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Groundwater Rule (5 of them). EPA lists 4 as archived, 4 as resolved and 1 as unaddressed. 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. 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.
