How does Interlaken Town compare with other water systems in Wasatch County?
By EPA's size categories, Interlaken Town is a very small system (500 people or fewer). Wasatch County has 58 active public water systems. Its population served is about 63% below the county average of 959 people per system, and accounts for 0.6% of the 55,608 people reported by systems filed under the county. Across Utah, the 1,133 active systems average 3,458 people each. Nationally, the average active community water system reports serving 6,703 people, so Interlaken Town 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. Utah has 540 active community water systems, 48% of the state's 1,133 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 898 Utah systems (79%) list groundwater as their primary source.
Who owns and regulates Interlaken Town?
EPA lists Interlaken Town as privately owned. The UT state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 32 of the 58 active systems in Wasatch County (55%) are also privately owned.
Does Interlaken Town have drinking water violations?
Of the 12 most recent violations in EPA's records, 6 are health-based, and the most recent began in September 2020. The violations listed here began between November 2008 and September 2020. By type: 5 contaminant level above the legal limit, 5 monitoring and reporting, 1 monitoring and 1 required treatment not met. The contaminant or rule involved most often is Total coliform bacteria (TCR) (5 of them). EPA lists 10 as resolved and 2 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. 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.
