How hard is the water in Scott County, VA?
9.3 grains per gallon
A softener is worth it here.
The median hardness measured in Scott County, VA is 159 mg/L as calcium carbonate, which is 9.3 gpg. That is hard on the USGS scale. It comes from 5 samples at 5 sites between 1995 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 6.4 and 12 gpg. That spread crosses a decision line, so some homes here land on a different answer. A $10 test strip on your own tap settles it. Confidence in the county figure: medium (how it is measured).
What to do next
At 9.3 gpg a softener is worth getting, mainly to protect the water heater and cut soap use. Get at least two quotes, ask each installer what grain capacity they are fitting, and check it against the sizing table below. Because Scott County straddles a decision line, check your own tap with a $10 test strip before you spend anything.

From 3.8 to 13.3 gpg
The softest single sample on record in Scott County was 65.7 mg/L and the hardest 227 mg/L, a 3-fold gap. The top quarter of sites read above 12 gpg and the bottom quarter below 6.4 gpg.
Wells 9.3 gpg, rivers and lakes 8.9 gpg
5 groundwater samples from 5 wells put the median at 159 mg/L. 304 surface samples from 23 sites put it at 152 mg/L. In Scott County the wells come out 0.4 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 203 lb of salt a year (6 bags of 40 lb, about $37), 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 $137 a year.
