How does Thermo Dyne compare with other water systems in Elkhart County?
By EPA's size categories, Thermo Dyne is a very small system (500 people or fewer). Elkhart County has 284 active public water systems. Its population served is well below the county average of 489 people per system, and accounts for less than 0.1% of the 138,737 people reported by systems filed under the county. Across Indiana, the 3,969 active systems average 1,456 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Thermo Dyne 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 Thermo Dyne?
EPA lists Thermo Dyne 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. 256 of the 284 active systems in Elkhart County (90%) are also privately owned.
Does Thermo Dyne have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in December 2025. The violations listed here began between January 2021 and December 2025. By type: 5 monitoring and reporting, 3 monitoring, 2 public notice, recordkeeping or other, 1 required treatment not met and 1 reporting. The contaminant or rule involved most often is Revised Total Coliform Rule (3 of them). EPA lists 7 as resolved, 4 as unaddressed and 1 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement. 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.
