Water Softener Installation in Randolph, MN
Randolph is supplied by Randolph, 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
Households in Randolph are served by Randolph, drawing ground water. Water out of the ground has picked up whatever the rock holds, and calcium and magnesium are what hardness means. Read the hardness line in the annual report before letting anybody specify a softener for the house.

Where the water comes fromGround water in Randolph
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.
Randolph serves 179 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
Randolph reports its hardness every year. Reading that one line takes a minute and it is the step most households skip. It will be given in milligrams per liter. Softeners are sized in grains per gallon, and one grain is about 17 mg/L.
The sizing calculation is a single multiplication, and doing it yourself turns a quote into something you can check. If your fixtures also stain orange, iron has to be settled first — oxidized iron clogs softener resin.
