How hard is the water in Scott County, IN?

9.6 grains per gallon

The median hardness measured in Scott County, IN is 164 mg/L as calcium carbonate, which is 9.6 gpg. That is hard on the USGS scale. It comes from 19 samples at 8 sites between 1997 and 2002, drawn from every sampling site in the county, wells and surface water together.

How much it varies here

Half the sites came in between 9.3 and 10.3 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: medium (how it is measured).

What to do next

At 9.6 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.

From 6.4 to 11.1 gpg

The softest single sample on record in Scott County was 109.5 mg/L and the hardest 190 mg/L, a 2-fold gap. The top quarter of sites read above 10.3 gpg and the bottom quarter below 9.3 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 209 lb of salt a year (6 bags of 40 lb, about $38), 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 $138 a year.
