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.

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.

Does Caterpillar Peoria Proving Grd have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in April 2023. The violations listed here began between January 2011 and April 2023. By type: 12 monitoring and reporting. The contaminants or rules involved are Arsenic, Nitrate, Alachlor (Lasso) and Endothall. EPA lists 10 as archived and 2 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.
