How does Big C Lumber compare with other water systems in St. Joseph County?
By EPA's size categories, Big C Lumber is a very small system (500 people or fewer). St. Joseph County has 221 active public water systems. Its population served is well below the county average of 989 people per system, and accounts for less than 0.1% of the 218,558 people reported by systems filed under the county.

Nationally, the average active non-transient non-community water system reports serving 430 people, so Big C Lumber is well below 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 Big C Lumber?
EPA lists Big C Lumber 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. 199 of the 221 active systems in St. Joseph County (90%) are also privately owned.
Does Big C Lumber have drinking water violations?
EPA's records list 4 violations for this system; 2 are health-based, and the most recent began in October 2025. The violations listed here began between January 2024 and October 2025. By type: 2 contaminant level above the legal limit and 2 monitoring and reporting. The contaminant or rule involved most often is Nitrate (3 of them). EPA lists 2 as archived, 1 as resolved and 1 as unaddressed. 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement.
