Well water hardness in West Virginia
Across 26 counties of West Virginia, the median well sampled by the USGS has 5.1 gpg of hardness. Counties range from 2.7 gpg (Randolph County) to 20.4 gpg (Jefferson 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.
