How does Highway Estates Water Assn compare with other water systems in Bonneville County?
By EPA's size categories, Highway Estates Water Assn is a very small system (500 people or fewer). Bonneville County has 126 active public water systems. Its population served is well below the county average of 1,089 people per system, and accounts for less than 0.1% of the 137,194 people reported by systems filed under the county.

Nationally, the average active community water system reports serving 6,703 people, so Highway Estates Water Assn is well below that figure.
What does “community water system” mean?

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 Highway Estates Water Assn?

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. 99 of the 126 active systems in Bonneville County (79%) are also privately owned.
Does Highway Estates Water Assn have drinking water violations?
Of the 12 most recent violations in EPA's records, 2 are health-based, and the most recent began in December 2021. The violations listed here began between January 2005 and December 2021. By type: 7 monitoring and reporting, 2 monitoring, 1 public notice, recordkeeping or other, 1 required treatment not met and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Revised Total Coliform Rule (3 of them). EPA lists 9 as resolved, 2 as archived and 1 as unaddressed. 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. 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement.
