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 Tetonia is well below that figure.
What does “community water system” mean?

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 Tetonia?

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. 6 of the 27 active systems in Teton County (22%) are also owned by a local government.
Does City of Tetonia have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in September 2018. The violations listed here began between July 1997 and September 2018. By type: 11 monitoring and reporting and 1 monitoring. The contaminant or rule involved most often is Lead and Copper Rule (4 of them). EPA lists 9 as resolved and 3 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.
