How does Midas Water System compare with other water systems in Bonner County?
By EPA's size categories, Midas Water System is a very small system (500 people or fewer). Bonner County has 140 active public water systems. Its population served is well below the county average of 276 people per system, and accounts for less than 0.1% of the 38,696 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 Midas Water System is well below 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 Midas Water System?
EPA lists Midas 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. 101 of the 140 active systems in Bonner County (72%) are also privately owned.
Does Midas Water System have drinking water violations?
Of the 12 most recent violations in EPA's records, 2 are health-based, and the most recent began in August 2021. The violations listed here began between July 1998 and August 2021. 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) (10 of them). 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. 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.
