How hard is the water in Shenandoah County, VA?
19 grains per gallon
A softener will pay its way here.
The median hardness measured in Shenandoah County, VA is 325 mg/L as calcium carbonate, which is 19 gpg. That is very hard on the USGS scale. It comes from 27 samples at 10 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 15.2 and 22 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 19 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 6.8 to 23.5 gpg
The softest single sample on record in Shenandoah County was 117 mg/L and the hardest 402 mg/L, a 3-fold gap. The top quarter of sites read above 22 gpg and the bottom quarter below 15.2 gpg.
Wells 19 gpg, rivers and lakes 11.1 gpg
27 groundwater samples from 10 wells put the median at 325 mg/L. 1,257 surface samples from 38 sites put it at 189.5 mg/L. In Shenandoah County the wells come out 7.9 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 415 lb of salt a year (11 bags of 40 lb, about $75), 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 $175 a year.
