How hard is the water in Keya Paha County, NE?
5.3 grains per gallon
Optional: a softener helps, but plenty of homes skip it.
The median hardness measured in Keya Paha County, NE is 91 mg/L as calcium carbonate, which is 5.3 gpg. That is moderately hard on the USGS scale. It comes from 16 samples at 3 sites between 1990 and 2013, drawn from every sampling site in the county, wells and surface water together.
How much it varies here
Half the sites came in between 4.5 and 9.5 gpg. That spread crosses a decision line, so some homes here land on a different answer. A $10 test strip on your own tap settles it. Confidence in the county figure: medium (how it is measured).
What to do next
At 5.3 gpg this is your call. Look for white film on glasses and crust on the shower head: if you see little of either, you can live without one. If you do want one, a 24,000-grain unit is enough, so ask for that size rather than a bigger one. Because Keya Paha County straddles a decision line, check your own tap with a $10 test strip before you spend anything.

From 3.7 to 13.6 gpg
The softest single sample on record in Keya Paha County was 62.7 mg/L and the hardest 233 mg/L, a 4-fold gap. The top quarter of sites read above 9.5 gpg and the bottom quarter below 4.5 gpg.
Wells 3.7 gpg, rivers and lakes 9.5 gpg
2 groundwater samples from 1 wells put the median at 62.7 mg/L. 14 surface samples from 2 sites put it at 162.1 mg/L. In Keya Paha County the rivers and lakes come out 5.8 gpg harder. Here the surface water reads harder than the wells, which often points to streams fed by limestone springs or irrigation return flow. A utility here that draws from the aquifer can deliver noticeably different water from a private well next door.
What a softener would cost to run
For a household of 3, a 24,000-grain unit covers a week between regenerations. Expect about 116 lb of salt a year (3 bags of 40 lb, about $21), and roughly 2,346 gallons of regeneration water. Installed, most units run $1,000 to $4,500; spread over 15 years with salt, that is about $121 a year.
