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 Isovolta Inc.?
EPA lists Isovolta Inc. 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. 132 of the 174 active systems in Rutland County (76%) are also privately owned.
