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. Indiana has 603 active non-transient non-community water systems, 15% of the state's 3,969 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 3,769 Indiana systems (95%) list groundwater as their primary source.
Who owns and regulates Nucor Steel?
EPA lists Nucor Steel as privately owned. The IN state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 29 of the 47 active systems in Montgomery County (62%) are also privately owned.
Does Nucor Steel have drinking water violations?
EPA's records list 8 violations for this system; 6 are health-based, and the most recent began in January 2025. The violations listed here began between April 1993 and January 2025. By type: 5 contaminant level above the legal limit, 1 monitoring and reporting, 1 required treatment not met and 1 monitoring. The contaminant or rule involved most often is Total coliform bacteria (TCR) (5 of them). EPA lists 7 as resolved and 1 as archived. 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. 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.
