Who owns and regulates Nitrex Inc. Chicago Operations?

Does Nitrex Inc. Chicago Operations have drinking water violations?

Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in October 2024. The violations listed here began between January 2020 and October 2024. By type: 8 monitoring and reporting, 2 monitoring, 1 required treatment not met and 1 reporting. The contaminant or rule involved most often is Lead and Copper Rule Revisions (2 of them).
