Plover water measures 260 mg/L (15.2 gpg) of hardness, very hard by USGS standards. The number comes from Plover Waterworks, dated August 2022.
At 260 mg/L, Plover is 90 mg/L above the typical Wisconsin figure of 170. Of the 10 nearest cities we track, 9 have softer water and 1 has harder. The range nearby runs from 32 mg/L in Wausau to 279 in New London.
What 260 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 260 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 × 15.2 gpg = 3,420 grains a day. A 24,000-grain unit regenerates about every 7 days.
