Water samples from around Papillion put hardness at about 234 mg/L (13.7 gpg), which would be very hard on the USGS scale. Treat this as a rough guide: it is the median of 643 samples taken across Sarpy County, mostly wells and streams, not a test of Papillion's treated tap water.
At 234 mg/L, Papillion is 85 mg/L above the typical Nebraska figure of 149. Of the 5 nearest cities we track, 4 have softer water and 1 has harder. The range nearby runs from 149 mg/L in Omaha to 315 in Fremont.
What 234 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 234 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 × 13.7 gpg = 3,078 grains a day. A 24,000-grain unit regenerates about every 7 days.
