How hard is the water in Gilmer County, WV?
5.1 grains per gallon
Optional: a softener helps, but plenty of homes skip it.
The median hardness measured in Gilmer County, WV is 88 mg/L as calcium carbonate, which is 5.1 gpg. That is moderately hard on the USGS scale. It comes from 3 samples at 3 sites between 2018 and 2018, drawn from every sampling site in the county, wells and surface water together.
How much it varies here
Half the sites came in between 3.9 and 7 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: low (how it is measured).
What to do next
At 5.1 gpg this is your call. Look for white film on glasses and crust on the shower head: if you see little of either, you can live without one. If you do want one, a 24,000-grain unit is enough, so ask for that size rather than a bigger one. Because Gilmer County straddles a decision line, check your own tap with a $10 test strip before you spend anything.
