How hard is the water in Waushara County, WI?

12.6 grains per gallon

The median hardness measured in Waushara County, WI is 215 mg/L as calcium carbonate, which is 12.6 gpg. That is very hard on the USGS scale. It comes from 29 samples at 15 sites between 1990 and 2026, 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 10.4 and 15.4 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 12.6 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 Waushara County straddles a decision line, check your own tap with a $10 test strip before you spend anything.

From 5.6 to 27.0 gpg

The softest single sample on record in Waushara County was 96.2 mg/L and the hardest 462.5 mg/L, a 5-fold gap. The top quarter of sites read above 15.4 gpg and the bottom quarter below 10.4 gpg.

Wells 12.6 gpg, rivers and lakes 9.2 gpg

29 groundwater samples from 15 wells put the median at 215 mg/L. 60 surface samples from 22 sites put it at 157.8 mg/L. In Waushara County the wells come out 3.4 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 24,000-grain unit covers a week between regenerations. Expect about 274 lb of salt a year (7 bags of 40 lb, about $49), 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 $149 a year.
