How hard is the water in Ohio County, WV?
7 grains per gallon
A softener is worth it here.
The median hardness measured in Ohio County, WV is 120 mg/L as calcium carbonate, which is 7 gpg. That is moderately hard on the USGS scale. It comes from 162 samples at 3 sites between 2000 and 2024, drawn from every sampling site in the county, wells and surface water together.
How much it varies here
Half the sites came in between 6.5 and 7.4 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 7 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 Ohio County straddles a decision line, check your own tap with a $10 test strip before you spend anything.
