How does Harmon Junction compare with other water systems in Churchill County?
By EPA's size categories, Harmon Junction is a very small system (500 people or fewer). Churchill County has 30 active public water systems.

Nevada has 258 active transient non-community water systems, 40% of the state's 643 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 557 Nevada systems (87%) list groundwater as their primary source.
Who owns and regulates Harmon Junction?
EPA lists Harmon Junction as privately owned. The NV state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 25 of the 30 active systems in Churchill County (83%) are also privately owned.
Does Harmon Junction have drinking water violations?
Of the 12 most recent violations in EPA's records, 4 are health-based, and the most recent began in October 2025. The violations listed here began between January 2005 and October 2025. By type: 5 monitoring and reporting, 3 required treatment not met, 3 monitoring and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Revised Total Coliform Rule (5 of them). EPA lists 8 as resolved, 2 as unaddressed and 2 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.
