American Fork water measures 223 mg/L (13.0 gpg) of hardness, very hard by USGS standards. The number comes from American Fork City, dated March 2025.
At 223 mg/L, American Fork is close to the typical Utah figure of 231 mg/L. Of the 10 nearest cities we track, 7 have softer water and 3 have harder. The range nearby runs from 94 mg/L in Draper to 256 in Pleasant Grove.
What 223 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 223 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 × 13.0 gpg = 2,934 grains a day. A 24,000-grain unit regenerates about every 8 days.
