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.

Purchased groundwater means the system buys groundwater from another public water system rather than drawing its own. 11 Idaho systems (0.6%) list purchased groundwater as their primary source.
