Does Marshell Station have drinking water violations?
EPA's records list 5 violations for this system; none is health-based, and the most recent began in February 2026. The violations listed here began between January 2017 and February 2026. By type: 3 monitoring and reporting, 1 public notice, recordkeeping or other and 1 monitoring. The contaminant or rule involved most often is Nitrate (3 of them). EPA lists 3 as resolved, 1 as unaddressed and 1 as archived. 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. 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.
