The water in West Salem carries roughly 244 mg/L of dissolved calcium and magnesium, or 14.3 grains per gallon. That is very hard water. The number comes from West Salem Waterworks, dated April 2025.
West Salem sits 74 mg/L above the typical Wisconsin figure of 170. Of the 10 nearest cities we track, 6 have softer water and 4 have harder. The range nearby runs from 49 mg/L in Chippewa Falls to 337 in Onalaska.
What 244 mg/L means at home
Scale forms fast here. Kettles and coffee makers need regular descaling, and showerheads clog unless you clean them.
Tank water heaters collect mineral sediment that insulates the water from the burner, so flushing the tank matters more than usual.
Dishes and glass shower doors spot easily. Soap scum and a dull film on hair or laundry are common complaints.
Hardness is not a health problem, and EPA sets no limit for it. It is a matter of scale and soap.
What to do about it
At 244 mg/L most of the trouble is scale, and only a few things deal with it.
Ion-exchange water softener
The standard whole-house fix. It swaps calcium and magnesium for sodium or potassium and needs salt plus a drain. Size it with the calculator below.
Salt-free conditioner
No salt and no drain line. It changes how minerals form scale instead of removing them, so water still tests hard.
Reverse osmosis or carbon filter
Under-sink reverse osmosis removes minerals from drinking water only. Plain carbon filters improve taste but do not soften.
3 people × 75 gallons a day × 14.3 gpg = 3,211 grains a day. A 24,000-grain unit regenerates about every 7 days.
