How does Nativity Catholic School compare with other water systems in Marion County?
By EPA's size categories, Nativity Catholic School is a very small system (500 people or fewer). Marion County has 57 active public water systems. Its population served is well below the county average of 16,663 people per system, and accounts for less than 0.1% of the 949,799 people reported by systems filed under the county.

Nationally, the average active non-transient non-community water system reports serving 430 people, so Nativity Catholic School is roughly in line with that figure.
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 Nativity Catholic School?
EPA lists Nativity Catholic School 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. 51 of the 57 active systems in Marion County (89%) are also privately owned.
Does Nativity Catholic 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 2025. The violations listed here began between October 1997 and January 2025. By type: 7 monitoring and reporting, 2 monitoring, 1 public notice, recordkeeping or other, 1 reporting and 1 required treatment not met. The contaminant or rule involved most often is Total coliform bacteria (TCR) (3 of them). EPA lists 8 as resolved and 4 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.
