Does Rock Hill WSC have drinking water violations?
EPA's records list 11 violations for this system; 9 are health-based, and the most recent began in January 2026. The violations listed here began between July 2004 and January 2026. By type: 9 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) (9 of them). EPA lists 7 as resolved and 4 as archived. 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.
