How hard is the water in Wayne County, KY?
11 grains per gallon
A softener will pay its way here.
The median hardness measured in Wayne County, KY is 188 mg/L as calcium carbonate, which is 11 gpg. That is very hard on the USGS scale. It comes from 252 samples at 7 sites between 2000 and 2014, drawn from every sampling site in the county, wells and surface water together.
How much it varies here
Half the sites came in between 7.9 and 11.1 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: medium (how it is measured).
What to do next
At 11 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. Because Wayne County straddles a decision line, check your own tap with a $10 test strip before you spend anything.

From 4.5 to 11.6 gpg
The softest single sample on record in Wayne County was 77 mg/L and the hardest 199 mg/L, a 3-fold gap. The top quarter of sites read above 11.1 gpg and the bottom quarter below 7.9 gpg.
Wells 11.1 gpg, rivers and lakes 10.9 gpg
8 groundwater samples from 2 wells put the median at 189.3 mg/L. 244 surface samples from 5 sites put it at 185.9 mg/L. In Wayne County the wells come out 0.2 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 24,000-grain unit covers a week between regenerations. Expect about 240 lb of salt a year (6 bags of 40 lb, about $43), 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 $143 a year.
