Does Planada Csd have drinking water violations?
EPA's records list 9 violations for this system; 3 are health-based, and the most recent began in October 2024. The violations listed here began between January 1983 and October 2024. By type: 4 monitoring and reporting, 2 contaminant level above the legal limit, 1 reporting, 1 required treatment not met and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Total coliform bacteria (TCR) (3 of them). EPA lists 6 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.
