How hard is the water in Love County, OK?
16.4 grains per gallon
A softener will pay its way here.
The median hardness measured in Love County, OK is 280 mg/L as calcium carbonate, which is 16.4 gpg. That is very hard on the USGS scale. It comes from 328 samples at 11 sites between 1992 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 14.7 and 22.4 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: high (how it is measured).
What to do next
At 16.4 gpg a softener pays its way here. Before you buy, check the quoted unit's grain capacity against the sizing table below, and ask whether it regenerates on demand, which uses less salt than a timer. Call your utility for its own report if you are on city water.

From 10.7 to 44.6 gpg
The softest single sample on record in Love County was 184 mg/L and the hardest 764 mg/L, a 4-fold gap. The top quarter of sites read above 22.4 gpg and the bottom quarter below 14.7 gpg.
Wells 21.6 gpg, rivers and lakes 15.7 gpg
1 groundwater samples from 1 wells put the median at 369 mg/L. 327 surface samples from 10 sites put it at 269.2 mg/L. In Love County the wells come out 5.9 gpg harder. Groundwater sits in contact with rock for years and picks up calcium and magnesium as it goes, so wells usually read harder. A utility here that draws from the river can deliver noticeably different water from a private well next door.
What a softener would cost to run
For a household of 3, a 24,000-grain unit covers a week between regenerations. Expect about 357 lb of salt a year (9 bags of 40 lb, about $64), 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 $164 a year.
