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. West Virginia has 55 active non-transient non-community water systems, 7% of the state's 791 active systems. Groundwater under the influence of surface water is well or spring water that the regulator has found to be affected by nearby surface water, so it is regulated under the surface-water treatment rules. 22 West Virginia systems (2.8%) list groundwater under influence of surface water as their primary source.
Who owns and regulates Northrup Grumman Innovation Systems, Inc.?
EPA lists Northrup Grumman Innovation Systems, Inc. as owned by the federal government.
