How does Black Rock Station compare with other water systems in Washoe County?
By EPA's size categories, Black Rock Station is a very small system (500 people or fewer). Washoe County has 64 active public water systems.

Nationally, the average active transient non-community water system reports serving 144 people, so Black Rock Station is well below that figure.

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.

Does Black Rock Station have drinking water violations?
EPA's records list 10 violations for this system; 2 are health-based, and the most recent began in January 2025. The violations listed here began between July 2005 and January 2025. By type: 8 monitoring and reporting and 2 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (8 of them). EPA lists 5 as resolved and 5 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.
