How hard is the water in Chippewa County, WI?

2.4 grains per gallon

You do not need a softener here.

The median hardness measured in Chippewa County, WI is 42 mg/L as calcium carbonate, which is 2.4 gpg. That is soft on the USGS scale. It comes from 252 samples at 29 sites between 1990 and 2013, drawn from every sampling site in the county, wells and surface water together.

How much it varies here

Half the sites came in between 0.7 and 3.3 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

You can skip the softener. At 2.4 gpg the most a softener would fix is the odd water spot. If a salesperson in Chippewa County says otherwise, ask to see their reading in grains per gallon and compare it with this one.

From 0.3 to 8.2 gpg

The softest single sample on record in Chippewa County was 4.9 mg/L and the hardest 140 mg/L, a 29-fold gap. The top quarter of sites read above 3.3 gpg and the bottom quarter below 0.7 gpg.

Wells 7.1 gpg, rivers and lakes 2.3 gpg

1 groundwater samples from 1 wells put the median at 122 mg/L. 251 surface samples from 28 sites put it at 39.8 mg/L. In Chippewa County the wells come out 4.8 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.
