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.

Massachusetts has 246 active non-transient non-community water systems, 15% of the state's 1,636 active systems. Purchased groundwater means the system buys groundwater from another public water system rather than drawing its own. 57 Massachusetts systems (3.5%) list purchased groundwater as their primary source.
