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. Washington has 400 active non-transient non-community water systems, 8.5% of the state's 4,705 active systems. Purchased surface water means the system buys surface water from another public water system rather than drawing its own. 130 Washington systems (2.8%) list purchased surface water as their primary source.

Who owns and regulates Energy Dept of/300 Area?

EPA lists Energy Dept of/300 Area as owned by the federal government.

Does Energy Dept of/300 Area have drinking water violations?

EPA's records list 10 violations for this system; all are health-based, and the most recent began in December 1994. The violations listed here began between January 1994 and December 1994. By type: 10 required treatment not met. The contaminant or rule involved most often is Surface Water Treatment Rule (10 of them). EPA lists 6 as archived and 4 as resolved.
