How hard is the water in Estill County, KY?

8.3 grains per gallon

The median hardness measured in Estill County, KY is 142 mg/L as calcium carbonate, which is 8.3 gpg. That is hard on the USGS scale. It comes from 81 samples at 3 sites between 1999 and 2007, drawn from every sampling site in the county, wells and surface water together.

How much it varies here

Half the sites came in between 6.7 and 8.3 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 8.3 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 Estill County straddles a decision line, check your own tap with a $10 test strip before you spend anything.
