Does Portland Water System have drinking water violations?
Of the 12 most recent violations in EPA's records, 4 are health-based, and the most recent began in April 2022. The violations listed here began between July 2002 and April 2022. By type: 7 monitoring and reporting, 2 contaminant level above the legal limit, 2 required treatment not met and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Interim Enhanced Surface Water Treatment Rule (7 of them). EPA lists 7 as resolved, 3 as archived and 2 as unaddressed. 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement.
