How hard is the water in Woodson County, KS?

6.3 grains per gallon

Optional: a softener helps, but plenty of homes skip it.

The median hardness measured in Woodson County, KS is 109 mg/L as calcium carbonate, which is 6.3 gpg. That is moderately hard on the USGS scale. It comes from 128 samples at 11 sites between 1992 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 4.7 and 7.3 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: high (how it is measured).

What to do next

At 6.3 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 Woodson County straddles a decision line, check your own tap with a $10 test strip before you spend anything.

From 3.4 to 18.1 gpg

The softest single sample on record in Woodson County was 58.5 mg/L and the hardest 310 mg/L, a 5-fold gap. The top quarter of sites read above 7.3 gpg and the bottom quarter below 4.7 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 138 lb of salt a year (4 bags of 40 lb, about $25), 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 $125 a year.
