How hard is the water in Warren County, NY?
4.5 grains per gallon
Optional: a softener helps, but plenty of homes skip it.
The median hardness measured in Warren County, NY is 77 mg/L as calcium carbonate, which is 4.5 gpg. That is moderately hard on the USGS scale. It comes from 27 samples at 24 sites between 1993 and 2022, 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 2.9 and 7.2 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 4.5 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. Because Warren County straddles a decision line, check your own tap with a $10 test strip before you spend anything.

From 1.3 to 28.8 gpg
The softest single sample on record in Warren County was 22.3 mg/L and the hardest 493.5 mg/L, a 22-fold gap. The top quarter of sites read above 7.2 gpg and the bottom quarter below 2.9 gpg.
Wells 4.5 gpg, rivers and lakes 0.8 gpg
27 groundwater samples from 24 wells put the median at 77.2 mg/L. 188 surface samples from 31 sites put it at 14.5 mg/L. In Warren County the wells come out 3.7 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 98 lb of salt a year (3 bags of 40 lb, about $18), 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 $118 a year.
