Of the 12 most recent violations in EPA's records, 4 are health-based, and the most recent began in December 2024. The violations listed here began between May 2015 and December 2024.

The contaminant or rule involved most often is Lead and Copper Rule Revisions (2 of them). EPA lists 10 as resolved and 2 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.
