How hard is the water in Blaine County, NE?
2.1 grains per gallon
You do not need a softener here.
The median hardness measured in Blaine County, NE is 36 mg/L as calcium carbonate, which is 2.1 gpg. That is soft on the USGS scale. It comes from 4 samples at 3 sites between 1994 and 2004, drawn from every sampling site in the county, wells and surface water together.
How much it varies here
Half the sites came in between 2 and 3.2 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: low (how it is measured).
What to do next
You can skip the softener. At 2.1 gpg the most a softener would fix is the odd water spot. If a salesperson in Blaine County says otherwise, ask to see their reading in grains per gallon and compare it with this one.
