How hard is the water in Chickasaw County, MS?

4.5 grains per gallon

Optional: a softener helps, but plenty of homes skip it.

The median hardness measured in Chickasaw County, MS is 77 mg/L as calcium carbonate, which is 4.5 gpg. That is moderately hard on the USGS scale. It comes from 12 samples at 1 sites between 2005 and 2005, drawn from every sampling site in the county, wells and surface water together.

How much it varies here

Half the sites came in between 4.5 and 4.5 gpg. The whole middle of that range gives the same answer, so a test of your own tap is unlikely to change it. Confidence in the county figure: low (how it is measured).

What to do next

At 4.5 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.

From 4.5 to 4.5 gpg

The softest single sample on record in Chickasaw County was 77.1 mg/L and the hardest 77.1 mg/L, a 1-fold gap. The top quarter of sites read above 4.5 gpg and the bottom quarter below 4.5 gpg.

What a softener would cost to run

For a household of 3, a 24,000-grain unit covers a week between regenerations. Expect about 98 lb of salt a year (3 bags of 40 lb, about $18), 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 $118 a year.
