Who owns and regulates Hominy?

Does Hominy have drinking water violations?

Of the 12 most recent violations in EPA's records, 5 are health-based, and the most recent began in December 2025. The violations listed here began between August 2025 and December 2025. By type: 6 monitoring and reporting, 4 contaminant level above the legal limit, 1 required treatment not met and 1 monitoring. The contaminant or rule involved most often is Total trihalomethanes (TTHM) (4 of them). EPA lists 7 as archived, 4 as resolved and 1 as addressed. 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. Addressed means the violation is not resolved or archived and is covered by formal enforcement.
