Does Nueces County Wcid 3 have drinking water violations?

Of the 12 most recent violations in EPA's records, 10 are health-based, and the most recent began in April 2026. The violations listed here began between January 2018 and April 2026. By type: 10 contaminant level above the legal limit, 1 public notice, recordkeeping or other and 1 monitoring and reporting. The contaminant or rule involved most often is Total trihalomethanes (TTHM) (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.
