Does Easton Pws have drinking water violations?
EPA's records list 5 violations for this system; 1 is health-based, and the most recent began in July 2025. The violations listed here began between November 1996 and July 2025. By type: 1 reporting, 1 public notice, recordkeeping or other, 1 monitoring, 1 contaminant level above the legal limit and 1 monitoring and reporting. The contaminant or rule involved most often is Total coliform bacteria (TCR) (2 of them). EPA lists 2 as unaddressed, 2 as resolved and 1 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.
