How hard is the water in Juneau County, WI?
3.7 grains per gallon
Optional: a softener helps, but plenty of homes skip it.
The median hardness measured in Juneau County, WI is 64 mg/L as calcium carbonate, which is 3.7 gpg. That is moderately hard on the USGS scale. It comes from 57 samples at 6 sites between 1990 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 2.4 and 4.3 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 3.7 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 Juneau County straddles a decision line, check your own tap with a $10 test strip before you spend anything.

From 1.3 to 12.6 gpg
The softest single sample on record in Juneau County was 23.1 mg/L and the hardest 215 mg/L, a 9-fold gap. The top quarter of sites read above 4.3 gpg and the bottom quarter below 2.4 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 81 lb of salt a year (3 bags of 40 lb, about $15), 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 $115 a year.
