How does Hern Water System compare with other water systems in Kootenai County?

By EPA's size categories, Hern Water System is a very small system (500 people or fewer). Kootenai County has 182 active public water systems. Its population served is well below the county average of 983 people per system, and accounts for less than 0.1% 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 transient non-community water system reports serving 144 people, so Hern Water System is about half of that figure.

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 Hern Water System?

EPA lists Hern Water System 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 Hern Water System have drinking water violations?

Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in July 2013. The violations listed here began between January 2004 and July 2013. By type: 11 monitoring and reporting and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Total coliform bacteria (TCR) (9 of them). EPA lists 9 as archived, 2 as resolved and 1 as unaddressed. 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. 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.
