Does Stewart have drinking water violations?
EPA's records list 10 violations for this system; 8 are health-based, and the most recent began in January 2026. The violations listed here began between October 2000 and January 2026. By type: 8 contaminant level above the legal limit and 2 monitoring and reporting. The contaminant or rule involved most often is Total trihalomethanes (TTHM) (6 of them). EPA lists 5 as archived and 5 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.
