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.

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.

Does Mill Creek East Elementary School have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in January 2009. The violations listed here began between July 2001 and January 2009. By type: 11 monitoring and reporting and 1 contaminant level above the legal limit. The contaminants or rules involved are Nitrate, Lead and Copper Rule, Total coliform bacteria (TCR) and Benzo(a)pyrene. EPA lists 9 as archived and 3 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.
