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. Massachusetts has 246 active non-transient non-community water systems, 15% of the state's 1,636 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 1,354 Massachusetts systems (83%) list groundwater as their primary source.
Who owns and regulates Mt Greylock Regional School?
EPA lists Mt Greylock Regional School as owned by a local government. The MA state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 33 of the 183 active systems in Berkshire County (18%) are also owned by a local government.
Does Mt Greylock Regional School have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in October 2019. The violations listed here began between April 2009 and October 2019. By type: 11 monitoring and reporting and 1 monitoring. The contaminants or rules involved are Radium-226, Revised Total Coliform Rule, Lead and Copper Rule and Glyphosate.
