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 Mountain Home Migrant Head Start?
EPA lists Mountain Home Migrant Head Start 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. 39 of the 44 active systems in Elmore County (89%) are also privately owned.
Does Mountain Home Migrant Head Start have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in June 2020. The violations listed here began between July 2004 and June 2020. By type: 7 monitoring and reporting, 4 monitoring and 1 required treatment not met. The contaminant or rule involved most often is Revised Total Coliform Rule (5 of them). EPA lists 6 as resolved and 6 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.
