How does Marketplace Square LLC. compare with other water systems in Plymouth County?
By EPA's size categories, Marketplace Square LLC. is a very small system (500 people or fewer). Plymouth County has 129 active public water systems.

Nationally, the average active non-transient non-community water system reports serving 430 people, so Marketplace Square LLC. is well below that figure.
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. Massachusetts has 246 active non-transient non-community water systems, 15% of the state's 1,636 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 1,354 Massachusetts systems (83%) list groundwater as their primary source.

EPA lists Marketplace Square LLC. as privately owned. The MA state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 85 of the 129 active systems in Plymouth County (66%) are also privately owned.
