How hard is the water in Hodgeman County, KS?
17.8 grains per gallon
A softener will pay its way here.
The median hardness measured in Hodgeman County, KS is 305 mg/L as calcium carbonate, which is 17.8 gpg. That is very hard on the USGS scale. It comes from 48 samples at 11 sites between 1994 and 2016, drawn from every sampling site in the county, wells and surface water together.
How much it varies here
Half the sites came in between 14.6 and 27.3 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: high (how it is measured).
What to do next
At 17.8 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 8.2 to 44.1 gpg
The softest single sample on record in Hodgeman County was 140 mg/L and the hardest 755 mg/L, a 5-fold gap. The top quarter of sites read above 27.3 gpg and the bottom quarter below 14.6 gpg.
What a softener would cost to run
For a household of 3, a 24,000-grain unit covers a week between regenerations. Expect about 389 lb of salt a year (10 bags of 40 lb, about $70), 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 $170 a year.
