Does City of Howe have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in July 2025. The violations listed here began between January 2022 and July 2025. By type: 10 monitoring and reporting, 1 reporting and 1 public notice, recordkeeping or other. The contaminants or rules involved are Lead and Copper Rule Revisions, Consumer Confidence Rule, Heptachlor and Di(2-ethylhexyl) phthalate. EPA lists 10 as archived, 1 as resolved and 1 as unaddressed. 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement.
