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. Illinois has 396 active non-transient non-community water systems, 10% of the state's 3,872 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 2,808 Illinois systems (73%) list groundwater as their primary source.
Who owns and regulates Ineos Styrolution America LLC?
EPA lists Ineos Styrolution America LLC as privately owned. The IL state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 162 of the 236 active systems in Will County (69%) are also privately owned.
Does Ineos Styrolution America LLC have drinking water violations?
EPA's records list 10 violations for this system; 1 is health-based, and the most recent began in March 2026. The violations listed here began between January 2017 and March 2026. By type: 7 monitoring and reporting, 1 public notice, recordkeeping or other, 1 reporting and 1 required treatment not met. The contaminant or rule involved most often is Chlorine (3 of them).
