Does Hoffman Rural Water Company have drinking water violations?
EPA's records list 10 violations for this system; 3 are health-based, and the most recent began in October 2024. The violations listed here began between December 1993 and October 2024.

The contaminant or rule involved most often is Lead and Copper Rule (3 of them). EPA lists 9 as resolved and 1 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.
