How hard is the water in Seward County, NE?
13.8 grains per gallon
A softener will pay its way here.
The median hardness measured in Seward County, NE is 236 mg/L as calcium carbonate, which is 13.8 gpg. That is very hard on the USGS scale. It comes from 17 samples at 17 sites between 1990 and 2020, drawn from groundwater wells, which is what most taps and private wells in the county draw on.
How much it varies here
Half the sites came in between 11.9 and 16.1 gpg. The whole middle of that range gives the same answer, so a test of your own tap is unlikely to change it. Confidence in the county figure: medium (how it is measured).
What to do next
At 13.8 gpg a softener pays its way here. Before you buy, check the quoted unit's grain capacity against the sizing table below, and ask whether it regenerates on demand, which uses less salt than a timer. Call your utility for its own report if you are on city water.

From 6.8 to 45.7 gpg
The softest single sample on record in Seward County was 117 mg/L and the hardest 783 mg/L, a 7-fold gap. The top quarter of sites read above 16.1 gpg and the bottom quarter below 11.9 gpg.
Wells 13.8 gpg, rivers and lakes 10.2 gpg
17 groundwater samples from 17 wells put the median at 236 mg/L. 26 surface samples from 2 sites put it at 175.1 mg/L. In Seward County the wells come out 3.6 gpg harder. Groundwater sits in contact with rock for years and picks up calcium and magnesium as it goes, so wells usually read harder. A utility here that draws from the river 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 301 lb of salt a year (8 bags of 40 lb, about $54), 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 $154 a year.
