How hard is the water in Fayette County, IN?
19.4 grains per gallon
A softener will pay its way here.
The median hardness measured in Fayette County, IN is 332 mg/L as calcium carbonate, which is 19.4 gpg. That is very hard on the USGS scale. It comes from 119 samples at 13 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 18.8 and 19.9 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: high (how it is measured).
What to do next
At 19.4 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 16.6 to 21.0 gpg
The softest single sample on record in Fayette County was 284 mg/L and the hardest 360 mg/L, a 1-fold gap. The top quarter of sites read above 19.9 gpg and the bottom quarter below 18.8 gpg.
Wells 19.8 gpg, rivers and lakes 19.3 gpg
1 groundwater samples from 1 wells put the median at 339 mg/L. 118 surface samples from 12 sites put it at 330 mg/L. In Fayette County the wells come out 0.5 gpg harder. Groundwater sits in contact with rock for years and picks up calcium and magnesium as it goes, so wells usually read harder. The two sources are close, so the county figure should hold whichever one your tap is on.
What a softener would cost to run
For a household of 3, a 32,000-grain unit covers a week between regenerations. Expect about 424 lb of salt a year (11 bags of 40 lb, about $76), 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 $176 a year.
