Does Sunset Mobile Home Park have drinking water violations?
EPA's records list 9 violations for this system; 2 are health-based, and the most recent began in October 2024. The violations listed here began between July 1995 and October 2024. By type: 6 monitoring and reporting, 1 required treatment not met, 1 reporting and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (3 of them). EPA lists 7 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. 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.
