How does Lowman Inn compare with other water systems in Boise County?

Idaho has 954 active transient non-community water systems, 49% of the state's 1,961 active systems.

Does Lowman Inn have drinking water violations?

Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in February 2026. The violations listed here began between December 2023 and February 2026. By type: 10 monitoring, 1 required treatment not met and 1 monitoring and reporting. The contaminant or rule involved most often is Revised Total Coliform Rule (10 of them). EPA lists 11 as archived and 1 as unaddressed.

Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement.
