How does Green Mountain Valley School compare with other water systems in Washington County?
By EPA's size categories, Green Mountain Valley School is a very small system (500 people or fewer). Washington County has 125 active public water systems. Its population served is well below the county average of 490 people per system, and accounts for 0.2% of the 61,286 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 Green Mountain Valley 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 Green Mountain Valley School?
EPA lists Green Mountain Valley 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. 94 of the 125 active systems in Washington County (75%) are also privately owned.
Does Green Mountain Valley School 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 2014. The violations listed here began between June 2000 and September 2014. By type: 6 contaminant level above the legal limit, 5 monitoring and reporting and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Total coliform bacteria (TCR) (9 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.
