Does Sierra Pines Mobile Home Park have drinking water violations?
EPA's records list 10 violations for this system; 1 is health-based, and the most recent began in October 2024. The violations listed here began between October 1981 and October 2024. By type: 8 monitoring and reporting, 1 reporting and 1 required treatment not met. The contaminant or rule involved most often is Total coliform bacteria (TCR) (7 of them). EPA lists 7 as resolved, 2 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.
