Does City of Asherton have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in May 2025. The violations listed here began between January 2022 and May 2025. By type: 9 monitoring and reporting, 1 public notice, recordkeeping or other, 1 reporting and 1 required treatment not met. The contaminant or rule involved most often is Lead and Copper Rule Revisions (2 of them). EPA lists 9 as archived and 3 as resolved. 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.
