How does Sigma Corporation compare with other water systems in Ocean County?

By EPA's size categories, Sigma Corporation is a very small system (500 people or fewer). Ocean County has 210 active public water systems. Its population served is well below the county average of 3,411 people per system, and accounts for less than 0.1% of the 716,388 people reported by systems filed under the county. Across New Jersey, the 3,496 active systems average 2,750 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Sigma Corporation 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. New Jersey has 637 active non-transient non-community water systems, 18% of the state's 3,496 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 3,313 New Jersey systems (95%) list groundwater as their primary source.

Who owns and regulates Sigma Corporation?

EPA lists Sigma Corporation as privately owned. The NJ state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 139 of the 210 active systems in Ocean County (66%) are also privately owned.
