How does Mansfield Professional Park compare with other water systems in Tolland County?

What does “non-transient non-community water system” mean?

Connecticut has 483 active non-transient non-community water systems, 20% of the state's 2,363 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 2,263 Connecticut systems (96%) list groundwater as their primary source.
