Does Southwest Arkansas Water System have drinking water violations?
Of the 12 most recent violations in EPA's records, 11 are health-based, and the most recent began in June 2025. The violations listed here began between October 2018 and June 2025. By type: 11 contaminant level above the legal limit and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Total trihalomethanes (TTHM) (8 of them). EPA lists 8 as resolved, 3 as archived and 1 as addressed. 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. Addressed means the violation is not resolved or archived and is covered by formal enforcement.
