By EPA's size categories, Sweet Montour School is a very small system (500 people or fewer). Gem County has 33 active public water systems.

Nationally, the average active non-transient non-community water system reports serving 430 people, so Sweet Montour School is well below that figure.
What does “non-transient non-community water system” mean?
A non-transient non-community water system regularly serves at least 25 of the same people for more than six months a year, but not where they live. Schools, factories, office buildings and hospitals with their own supply are typical examples. Idaho has 242 active non-transient non-community water systems, 12% 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 Sweet Montour School?
EPA lists Sweet Montour School as owned by a local government. 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. 3 of the 33 active systems in Gem County (9.1%) are also owned by a local government.
Does Sweet Montour School have drinking water violations?
Of the 12 most recent violations in EPA's records, 2 are health-based, and the most recent began in January 2025. The violations listed here began between September 2017 and January 2025. By type: 5 public notice, recordkeeping or other, 2 required treatment not met, 2 monitoring and reporting, 2 monitoring and 1 reporting. The contaminant or rule involved most often is Public Notice (5 of them). EPA lists 7 as resolved, 4 as unaddressed and 1 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement. 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.
