How does Pcs Phosphate compare with other water systems in LaSalle County?

Across Illinois, the 3,872 active systems average 3,204 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Pcs Phosphate is well below that figure.

What does “non-transient non-community water system” mean?

Groundwater means the system draws its water from wells or springs fed by underground aquifers. 2,808 Illinois systems (73%) list groundwater as their primary source.
