Does Peterson Prairie have drinking water violations?
EPA's records list 8 violations for this system; 4 are health-based, and the most recent began in January 2024. The violations listed here began between September 1997 and January 2024. By type: 4 monitoring and reporting and 4 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (6 of them). EPA lists 6 as archived and 2 as resolved. 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.
