How does Rail One USA compare with other water systems in Clinton County?
By EPA's size categories, Rail One USA is a very small system (500 people or fewer). Clinton County has 29 active public water systems. Its population served is well below the county average of 1,391 people per system, and accounts for less than 0.1% of the 40,325 people reported by systems filed under the county. Across Iowa, the 1,828 active systems average 1,718 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Rail One USA 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. Iowa has 118 active non-transient non-community water systems, 6.5% of the state's 1,828 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 1,502 Iowa systems (82%) list groundwater as their primary source.
