Groundwater means the system draws its water from wells or springs fed by underground aquifers. 1,861 Idaho systems (95%) list groundwater as their primary source.
Who owns and regulates Winder Water System?

Does Winder Water System have drinking water violations?
Of the 12 most recent violations in EPA's records, 6 are health-based, and the most recent began in March 2026. The violations listed here began between December 2020 and March 2026. By type: 6 required treatment not met and 6 monitoring and reporting. The contaminant or rule involved most often is Groundwater Rule (6 of them). EPA lists 6 as unaddressed, 5 as archived and 1 as resolved. 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. 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.
