How hard is the water in Wabash County, IN?

15.3 grains per gallon

A softener will pay its way here.

The median hardness measured in Wabash County, IN is 263 mg/L as calcium carbonate, which is 15.3 gpg. That is very hard on the USGS scale. It comes from 310 samples at 4 sites between 1991 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 11 and 19.1 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 15.3 gpg a softener pays its way here. Before you buy, check the quoted unit's grain capacity against the sizing table below, and ask whether it regenerates on demand, which uses less salt than a timer. Call your utility for its own report if you are on city water.

From 8.8 to 19.7 gpg

The softest single sample on record in Wabash County was 150 mg/L and the hardest 337 mg/L, a 2-fold gap. The top quarter of sites read above 19.1 gpg and the bottom quarter below 11 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 335 lb of salt a year (9 bags of 40 lb, about $60), 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 $160 a year.
