How hard is the water in Paulding County, OH?
14.7 grains per gallon
A softener will pay its way here.
The median hardness measured in Paulding County, OH is 252 mg/L as calcium carbonate, which is 14.7 gpg. That is very hard on the USGS scale. It comes from 446 samples at 45 sites between 1995 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 13.7 and 16.4 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 14.7 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 6.2 to 29.6 gpg
The softest single sample on record in Paulding County was 106 mg/L and the hardest 507.5 mg/L, a 5-fold gap. The top quarter of sites read above 16.4 gpg and the bottom quarter below 13.7 gpg.
Wells 29.6 gpg, rivers and lakes 14.6 gpg
4 groundwater samples from 2 wells put the median at 506.3 mg/L. 413 surface samples from 41 sites put it at 250 mg/L. In Paulding County the wells come out 15.0 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 321 lb of salt a year (9 bags of 40 lb, about $58), 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 $158 a year.
