Does La Belle Pws have drinking water violations?
EPA's records list 10 violations for this system; 1 is health-based, and the most recent began in December 2025. The violations listed here began between January 1994 and December 2025. By type: 7 monitoring and reporting, 1 monitoring, 1 public notice, recordkeeping or other 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 8 as resolved, 1 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.
