How hard is the water in Choctaw County, AL?
3.2 grains per gallon
You do not need a softener here.
The median hardness measured in Choctaw County, AL is 55 mg/L as calcium carbonate, which is 3.2 gpg. That is soft on the USGS scale. It comes from 671 samples at 25 sites between 1990 and 2025, drawn from every sampling site in the county, wells and surface water together.
How much it varies here
Half the sites came in between 1.6 and 3.6 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: high (how it is measured).
What to do next
You can skip the softener. At 3.2 gpg the most a softener would fix is the odd water spot. If a salesperson in Choctaw County says otherwise, ask to see their reading in grains per gallon and compare it with this one. Because Choctaw County straddles a decision line, check your own tap with a $10 test strip before you spend anything.
