Who owns and regulates Mcclelland WSC?

Does Mcclelland WSC have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in April 2026. The violations listed here began between July 2019 and April 2026. By type: 10 monitoring and reporting and 2 monitoring. The contaminant or rule involved most often is Lead and Copper Rule (5 of them). EPA lists 10 as resolved, 1 as unaddressed 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement. 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.
