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 Obrien Steel?
EPA lists Obrien Steel 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. 39 of the 58 active systems in Woodford County (67%) are also privately owned.
Does Obrien Steel have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in October 2023. The violations listed here began between January 2023 and October 2023. By type: 12 monitoring and reporting. The contaminants or rules involved are Lead and Copper Rule, Lindane (gamma-BHC), Di(2-ethylhexyl) adipate and Atrazine. EPA lists 11 as archived and 1 as resolved. Archived means the violation was not marked resolved but is more than five years past the end of the noncompliance period, so it no longer counts toward current compliance status. Resolved means at least one resolving action is on record: the system returned to compliance, the rule no longer applies, or no further action was needed.
