How hard is the water in Elk County, KS?

9.9 grains per gallon

The median hardness measured in Elk County, KS is 170 mg/L as calcium carbonate, which is 9.9 gpg. That is hard on the USGS scale. It comes from 127 samples at 13 sites between 1993 and 2017, drawn from every sampling site in the county, wells and surface water together.

How much it varies here

Half the sites came in between 7 and 12.9 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 9.9 gpg a softener is worth getting, mainly to protect the water heater and cut soap use. Get at least two quotes, ask each installer what grain capacity they are fitting, and check it against the sizing table below. Because Elk County straddles a decision line, check your own tap with a $10 test strip before you spend anything.

From 3.4 to 22.5 gpg

The softest single sample on record in Elk County was 59 mg/L and the hardest 385 mg/L, a 7-fold gap. The top quarter of sites read above 12.9 gpg and the bottom quarter below 7 gpg. So even here some sites draw water soft enough to need nothing at all.

What a softener would cost to run

For a household of 3, a 24,000-grain unit covers a week between regenerations. Expect about 217 lb of salt a year (6 bags of 40 lb, about $39), 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 $139 a year.
