How does Evonik Corporation compare with other water systems in Sedgwick County?
By EPA's size categories, Evonik Corporation is a very small system (500 people or fewer). Sedgwick County has 29 active public water systems. Its population served is well below the county average of 17,187 people per system, and accounts for less than 0.1% of the 498,426 people reported by systems filed under the county. Across Kansas, the 1,041 active systems average 2,800 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Evonik 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. Kansas has 40 active non-transient non-community water systems, 3.8% of the state's 1,041 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 587 Kansas systems (56%) list groundwater as their primary source.
Who owns and regulates Evonik Corporation?
EPA lists Evonik Corporation as privately owned. The KS state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 7 of the 29 active systems in Sedgwick County (24%) are also privately owned.
