How does Perpetua Resources compare with other water systems in Valley County?
By EPA's size categories, Perpetua Resources is a very small system (500 people or fewer). Valley County has 57 active public water systems. Its population served is about half of the county average of 218 people per system, and accounts for 1% of the 12,448 people reported by systems filed under the county. Across Idaho, the 1,961 active systems average 899 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Perpetua Resources is well below that figure.
What does “non-transient non-community water system” mean?
A non-transient non-community water system regularly serves at least 25 of the same people for more than six months a year, but not where they live. Schools, factories, office buildings and hospitals with their own supply are typical examples. Idaho has 242 active non-transient non-community water systems, 12% of the state's 1,961 active systems. 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 Perpetua Resources?
EPA lists Perpetua Resources as privately owned. The ID state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 42 of the 57 active systems in Valley County (74%) are also privately owned.
Does Perpetua Resources have drinking water violations?

By type: 12 monitoring and reporting. The contaminants or rules involved are Lead and Copper Rule, 1,1,2-Trichloroethane, Carbon tetrachloride and Benzo(a)pyrene.
