Wisconsin has 891 active non-transient non-community water systems, 8.1% of the state's 11,056 active systems.

Does Petro Travel Plaza #403 have drinking water violations?
EPA's records list 10 violations for this system; 1 is health-based, and the most recent began in October 2025. The violations listed here began between January 1991 and October 2025. By type: 8 monitoring and 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) (7 of them). EPA lists 5 as resolved, 3 as archived and 2 as unaddressed. 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement.
