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.

Does Elk Bend Unit 1 have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in August 2024. The violations listed here began between January 2023 and August 2024. By type: 11 monitoring and reporting and 1 monitoring. The contaminants or rules involved are Revised Total Coliform Rule, Vinyl chloride, Styrene and Trichloroethylene. EPA lists 11 as archived and 1 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.
