How does Eml compare with other water systems in Marathon County?
By EPA's size categories, Eml is a very small system (500 people or fewer). Marathon County has 196 active public water systems.

Across Wisconsin, the 11,056 active systems average 469 people each. Nationally, the average active transient non-community water system reports serving 144 people, so Eml is well below that figure.
What does “transient non-community water system” mean?

Wisconsin has 9,112 active transient non-community water systems, 82% of the state's 11,056 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 10,978 Wisconsin systems (99%) list groundwater as their primary source.
