How does Acceleron compare with other water systems in Hartford County?

By EPA's size categories, Acceleron is a very small system (500 people or fewer). Hartford County has 219 active public water systems. Its population served is well below the county average of 3,818 people per system, and accounts for less than 0.1% of the 836,032 people reported by systems filed under the county. Across Connecticut, the 2,363 active systems average 1,247 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Acceleron 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. 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.

Who owns and regulates Acceleron?

EPA lists Acceleron as privately owned. The CT state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 179 of the 219 active systems in Hartford County (82%) are also privately owned.
