How hard is the water in Garden County, NE?
18.2 grains per gallon
A softener will pay its way here.
The median hardness measured in Garden County, NE is 311 mg/L as calcium carbonate, which is 18.2 gpg. That is very hard on the USGS scale. It comes from 68 samples at 36 sites between 1990 and 2011, 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 10.1 and 23 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: high (how it is measured).
What to do next
At 18.2 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. Because Garden County straddles a decision line, check your own tap with a $10 test strip before you spend anything.

From 3.3 to 31.5 gpg
The softest single sample on record in Garden County was 56.6 mg/L and the hardest 540 mg/L, a 10-fold gap. The top quarter of sites read above 23 gpg and the bottom quarter below 10.1 gpg. So even here some sites draw water soft enough to need nothing at all.
Wells 18.2 gpg, rivers and lakes 6.3 gpg
68 groundwater samples from 36 wells put the median at 311 mg/L. 76 surface samples from 4 sites put it at 108.3 mg/L. In Garden County the wells come out 11.9 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 397 lb of salt a year (10 bags of 40 lb, about $71), 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 $171 a year.
