Does Cypress Valley WSC Plant 2 have drinking water violations?
Of the 12 most recent violations in EPA's records, 5 are health-based, and the most recent began in April 2026. The violations listed here began between July 2025 and April 2026.

The contaminant or rule involved most often is Total trihalomethanes (TTHM) (7 of them). EPA lists 5 as archived, 4 as resolved and 3 as unaddressed. 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.
