How does Danforth Plaza compare with other water systems in Penobscot County?

By EPA's size categories, Danforth Plaza is a very small system (500 people or fewer). Penobscot County has 169 active public water systems. Its population served is well below the county average of 547 people per system, and accounts for less than 0.1% of the 92,416 people reported by systems filed under the county. Across Maine, the 1,862 active systems average 503 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Danforth Plaza 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. Maine has 385 active non-transient non-community water systems, 21% of the state's 1,862 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 1,780 Maine systems (96%) list groundwater as their primary source.

EPA lists Danforth Plaza as privately owned. The ME state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 127 of the 169 active systems in Penobscot County (75%) are also privately owned.
