How does Pumpkin Hollow Shaft Site compare with other water systems in Lyon County?
By EPA's size categories, Pumpkin Hollow Shaft Site is a very small system (500 people or fewer). Lyon County has 30 active public water systems. Its population served is well below the county average of 1,710 people per system, and accounts for 0.4% of the 51,309 people reported by systems filed under the county. Across Nevada, the 643 active systems average 5,508 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Pumpkin Hollow Shaft Site is about half of 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. Nevada has 161 active non-transient non-community water systems, 25% of the state's 643 active systems. Purchased groundwater means the system buys groundwater from another public water system rather than drawing its own. 9 Nevada systems (1.4%) list purchased groundwater as their primary source.
Who owns and regulates Pumpkin Hollow Shaft Site?
EPA lists Pumpkin Hollow Shaft Site 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. 20 of the 30 active systems in Lyon County (67%) are also privately owned.
Does Pumpkin Hollow Shaft Site have drinking water violations?
Of the 12 most recent violations in EPA's records, 2 are health-based, and the most recent began in January 2026. The violations listed here began between January 2014 and January 2026. By type: 9 monitoring and reporting, 1 required treatment not met, 1 reporting and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Haloacetic acids (HAA5) (3 of them). EPA lists 7 as resolved, 4 as archived and 1 as unaddressed. 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement.
