How hard is the water in Wyoming County, PA?
5.6 grains per gallon
Optional: a softener helps, but plenty of homes skip it.
The median hardness measured in Wyoming County, PA is 96 mg/L as calcium carbonate, which is 5.6 gpg. That is moderately hard on the USGS scale. It comes from 18 samples at 7 sites between 1993 and 2026, drawn from groundwater wells, which is what most taps and private wells in the county draw on.
How much it varies here
Half the sites came in between 5 and 6.9 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: medium (how it is measured).
What to do next
At 5.6 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 4.4 to 7.5 gpg
The softest single sample on record in Wyoming County was 75.4 mg/L and the hardest 129 mg/L, a 2-fold gap. The top quarter of sites read above 6.9 gpg and the bottom quarter below 5 gpg.
Wells 5.6 gpg, rivers and lakes 3.2 gpg
18 groundwater samples from 7 wells put the median at 95.6 mg/L. 1,087 surface samples from 31 sites put it at 55 mg/L. In Wyoming County the wells come out 2.4 gpg harder. Groundwater sits in contact with rock for years and picks up calcium and magnesium as it goes, so wells usually read harder. The two sources are close, so the county figure should hold whichever one your tap is on.
What a softener would cost to run
For a household of 3, a 24,000-grain unit covers a week between regenerations. Expect about 122 lb of salt a year (4 bags of 40 lb, about $22), 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 $122 a year.
