Water Softener Installation in Mounds, IL
Mounds is supplied by Mounds, 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 Mounds is Mounds, 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 Mounds
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.
Mounds serves 478 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 annual water quality report from Mounds carries the hardness figure. Get it first, because everything downstream depends on it. It will be given in milligrams per liter. Softeners are sized in grains per gallon, and one grain is about 17 mg/L.
From there, the sizing math takes a minute and tells you what capacity actually fits the household. If your fixtures also stain orange, iron has to be settled first — oxidized iron clogs softener resin.
