How hard is the water in Orange County, VT?
7.7 grains per gallon
A softener is worth it here.
The median hardness measured in Orange County, VT is 131 mg/L as calcium carbonate, which is 7.7 gpg. That is hard on the USGS scale. It comes from 8 samples at 7 sites between 1994 and 2025, 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 4.7 and 9.7 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 7.7 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 Orange County straddles a decision line, check your own tap with a $10 test strip before you spend anything.

From 3.1 to 10.7 gpg
The softest single sample on record in Orange County was 52.7 mg/L and the hardest 183 mg/L, a 3-fold gap. The top quarter of sites read above 9.7 gpg and the bottom quarter below 4.7 gpg. So even here some sites draw water soft enough to need nothing at all.
Wells 7.7 gpg, rivers and lakes 5.5 gpg
8 groundwater samples from 7 wells put the median at 131 mg/L. 731 surface samples from 181 sites put it at 94 mg/L. In Orange County the wells come out 2.2 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 167 lb of salt a year (5 bags of 40 lb, about $30), 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 $130 a year.
