Does Saddleback Mutual Water Co. have drinking water violations?
EPA's records list 10 violations for this system; 2 are health-based, and the most recent began in October 2024. The violations listed here began between October 1982 and October 2024. By type: 6 public notice, recordkeeping or other, 1 reporting, 1 required treatment not met, 1 contaminant level above the legal limit and 1 monitoring and reporting. The contaminant or rule involved most often is Lead and Copper Rule Revisions (2 of them). EPA lists 6 as archived, 2 as unaddressed and 2 as resolved. 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement. 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.
