How hard is the water in Orange County, NY?
13.3 grains per gallon
A softener will pay its way here.
The median hardness measured in Orange County, NY is 228 mg/L as calcium carbonate, which is 13.3 gpg. That is very hard on the USGS scale. It comes from 27 samples at 25 sites between 1993 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 6.5 and 18.6 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 13.3 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. Because Orange County straddles a decision line, check your own tap with a $10 test strip before you spend anything.

From 1.9 to 31.0 gpg
The softest single sample on record in Orange County was 33 mg/L and the hardest 531 mg/L, a 16-fold gap. The top quarter of sites read above 18.6 gpg and the bottom quarter below 6.5 gpg. So even here some sites draw water soft enough to need nothing at all.
Wells 13.3 gpg, rivers and lakes 1.4 gpg
27 groundwater samples from 25 wells put the median at 228 mg/L. 322 surface samples from 44 sites put it at 24 mg/L. In Orange County the wells come out 11.9 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 291 lb of salt a year (8 bags of 40 lb, about $52), 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 $152 a year.
