Well water hardness in Nebraska

Across 54 counties of Nebraska, the median well sampled by the USGS has 14.8 gpg of hardness. Counties range from 2.9 gpg (Cherry County) to 27.6 gpg (Harlan County).

Millions of American households drink water from their own well. No utility tests that water and no water quality report covers it. These pages summarise the hardness the U.S. Geological Survey measured in wells county by county, so you know what to expect before you test your own well.
