Does Pendleton-Pea Ridge Water Assn have drinking water violations?
Of the 12 most recent violations in EPA's records, 3 are health-based, and the most recent began in August 2025. The violations listed here began between April 2011 and August 2025. By type: 5 public notice, recordkeeping or other, 2 required treatment not met, 2 monitoring and reporting, 1 reporting, 1 monitoring and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Consumer Confidence Rule (5 of them). EPA lists 10 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.
