What does “transient non-community water system” mean?
A transient non-community water system serves places where people do not stay long, such as gas stations and campgrounds, and regularly serves at least 25 people a day for at least 60 days a year. Idaho has 954 active transient non-community water systems, 49% 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 Red Horse Mountain?
EPA lists Red Horse Mountain 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. 123 of the 182 active systems in Kootenai County (68%) are also privately owned.
Does Red Horse Mountain have drinking water violations?
Of the 12 most recent violations in EPA's records, 2 are health-based, and the most recent began in September 2019. The violations listed here began between April 2006 and September 2019. By type: 9 monitoring and reporting, 2 contaminant level above the legal limit and 1 monitoring. The contaminant or rule involved most often is Total coliform bacteria (TCR) (11 of them). EPA lists 12 as archived. 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.
