Water Softener Installation in Mound City, IL
Mound City is supplied by Mound City, which draws ground water. That one fact does more to predict whether a softener is worth it here than anything a salesperson will ask you on the phone.
The short version
The supplier for Mound City is Mound City, drawing ground water. Groundwater has been in contact with rock, which is where calcium and magnesium come from, so hardness is the likelier finding. Whether a softener is worth installing turns on the hardness figure that supplier publishes each year, not on anything assessed over the telephone.

Where the water comes fromGround water in Mound City
A system this small is almost always drawing from wells, and well water is where hardness comes from. Rain that soaks through soil and rock picks up calcium and magnesium on the way down, and it arrives at the tap carrying them.
Mound City serves 166 service connections. Figures are what the system filed with the EPA, refreshed for the second quarter of 2026.

What to do with thatGet your hardness figure
The figure you need is already published: Mound City issues an annual water quality report, and hardness is one of the lines on it. The units differ on purpose-built confusion: mg/L on the report, grains per gallon on the equipment.
Size it yourself first. A bigger unit is not a safer one; EPA is explicit that oversizing wastes water. If your fixtures also stain orange, iron has to be settled first — oxidized iron clogs softener resin.
