Well water hardness in Georgia
Across 19 counties of Georgia, the median well sampled by the USGS has 5.7 gpg of hardness. Counties range from 1.8 gpg (Tift County) to 13.2 gpg (Glynn 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.
