How hard is the water in Niagara County, NY?
78.9 grains per gallon
A softener will pay its way here.
The median hardness measured in Niagara County, NY is 1350 mg/L as calcium carbonate, which is 78.9 gpg. That is very hard on the USGS scale. It comes from 41 samples at 33 sites between 1990 and 2023, 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 50.2 and 102.2 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 78.9 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 10.0 to 137.9 gpg
The softest single sample on record in Niagara County was 171 mg/L and the hardest 2,360 mg/L, a 14-fold gap. The top quarter of sites read above 102.2 gpg and the bottom quarter below 50.2 gpg.
Wells 78.9 gpg, rivers and lakes 13.3 gpg
41 groundwater samples from 33 wells put the median at 1350 mg/L. 242 surface samples from 13 sites put it at 228 mg/L. In Niagara County the wells come out 65.6 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, the water is harder than a standard single tank handles in a week, so plan on a larger or twin-tank unit. Expect about 1,722 lb of salt a year (44 bags of 40 lb, about $310), 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 $410 a year.
