How does Us Ecology Nevada compare with other water systems in Nye County?
By EPA's size categories, Us Ecology Nevada is a very small system (500 people or fewer). Nye County has 89 active public water systems. Its population served is well below the county average of 379 people per system, and accounts for 0.3% of the 33,742 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 Us Ecology Nevada 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. Nevada has 161 active non-transient non-community water systems, 25% 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 Us Ecology Nevada?
EPA lists Us Ecology Nevada as owned by a state government. 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. 4 of the 89 active systems in Nye County (4.5%) are also owned by a state government.
