How does Mountain School compare with other water systems in Orange County?
By EPA's size categories, Mountain School is a very small system (500 people or fewer). Orange County has 70 active public water systems. Its population served is well below the county average of 298 people per system, and accounts for 0.3% of the 20,846 people reported by systems filed under the county. Across Vermont, the 1,357 active systems average 477 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Mountain 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. Vermont has 253 active non-transient non-community water systems, 19% of the state's 1,357 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 1,243 Vermont systems (92%) list groundwater as their primary source.
Who owns and regulates Mountain School?
EPA lists Mountain School as privately owned. The VT state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 48 of the 70 active systems in Orange County (69%) are also privately owned.
Does Mountain School have drinking water violations?
EPA's records list 3 violations for this system; 2 are health-based, and the most recent began in March 2017. The violations listed here began between August 2001 and March 2017. By type: 2 contaminant level above the legal limit and 1 monitoring. The contaminant or rule involved most often is Total coliform bacteria (TCR) (2 of them). EPA lists 2 as resolved 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. 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.
