Georgia Well Water
Last reviewed October 29, 2026
Overview
Private wells supply water to many Georgia households. Because they are generally not regulated like public systems under the federal Safe Drinking Water Act, testing and wellhead protection are the owner’s responsibility.
Hydrogeology & what it means
Georgia uses the Floridan aquifer in the south and crystalline/Piedmont aquifers in the north. The documented regional concerns below indicate what is worth testing for — not what any individual well contains.
Documented regional concerns
- Radon in water where granitic or uranium-bearing bedrock is present.
- Saltwater intrusion and elevated chloride/sodium in coastal or over-pumped areas.
- Hard water from carbonate (limestone/dolomite) aquifers.
- Naturally acidic (low pH) water that can corrode plumbing and leach metals such as lead or copper.
These are documented possibilities, not a reading of your well
Frequently asked questions
What should well owners in Georgia test for?
A practical panel for Georgia private wells includes Total coliform bacteria, Nitrate (as N), pH, Radon, Chloride, Total dissolved solids, Total hardness, Lead, Copper. Test bacteria and nitrate at least annually and use a state-certified laboratory; confirm local recommendations with your state health department and University of Georgia Cooperative Extension.
Are private wells regulated in Georgia?
Private wells are generally not covered by the federal Safe Drinking Water Act, though Georgia or local rules may apply to construction, permitting, or testing. Public-system limits such as EPA MCLs are useful reference points, not automatic legal limits for your well.
