Does River Ranch Mobile Home Park have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in October 2024. The violations listed here began between October 1980 and October 2024. By type: 6 monitoring and reporting, 4 public notice, recordkeeping or other, 1 required treatment not met and 1 reporting. The contaminant or rule involved most often is Lead and Copper Rule (3 of them). EPA lists 6 as archived, 4 as resolved and 2 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.
