How does City of Harrison compare with other water systems in Kootenai County?
By EPA's size categories, City of Harrison is a very small system (500 people or fewer). Kootenai County has 182 active public water systems. Its population served is about half of the county average of 983 people per system, and accounts for 0.3% of the 178,930 people reported by systems filed under the county. Across Idaho, the 1,961 active systems average 899 people each. Nationally, the average active community water system reports serving 6,703 people, so City of Harrison is well below that figure.
What does “community water system” mean?
A community water system serves at least 15 connections used by year-round residents, or regularly serves at least 25 year-round residents. Homes, apartments and mobile-home parks are served by these. Idaho has 765 active community water systems, 39% 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 City of Harrison?
EPA lists City of Harrison as owned by a local government. 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. 30 of the 182 active systems in Kootenai County (16%) are also owned by a local government.
Does City of Harrison have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in December 2025. The violations listed here began between January 2011 and December 2025. By type: 8 monitoring and reporting, 3 monitoring and 1 required treatment not met. The contaminant or rule involved most often is Chlorine (6 of them). EPA lists 9 as resolved, 2 as unaddressed and 1 as archived. 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. 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.
