How hard is the water in Monroe County, NY?
25.7 grains per gallon
A softener will pay its way here.
The median hardness measured in Monroe County, NY is 440 mg/L as calcium carbonate, which is 25.7 gpg. That is very hard on the USGS scale. It comes from 619 samples at 33 sites between 1990 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 21.7 and 42.9 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: high (how it is measured).
What to do next
At 25.7 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 1.2 to 277.5 gpg
The softest single sample on record in Monroe County was 20.7 mg/L and the hardest 4,750 mg/L, a 229-fold gap. The top quarter of sites read above 42.9 gpg and the bottom quarter below 21.7 gpg. So even here some sites draw water soft enough to need nothing at all.
Wells 25.7 gpg, rivers and lakes 17.3 gpg
619 groundwater samples from 33 wells put the median at 440 mg/L. 295 surface samples from 18 sites put it at 296 mg/L. In Monroe County the wells come out 8.4 gpg harder. Groundwater sits in contact with rock for years and picks up calcium and magnesium as it goes, so wells usually read harder. 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 40,000-grain unit covers a week between regenerations. Expect about 561 lb of salt a year (15 bags of 40 lb, about $101), 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 $201 a year.
