Georgia does not require routine testing of existing private wells, but DNR EPD recommends annual testing for total coliform bacteria, E. coli, and nitrates. County boards of health can provide lists of state-certified laboratories, and some county extension offices offer periodic low-cost testing events. New well construction requires a water quality test before the well permit is finalized under Georgia's Water Well Standards Act.
Basic bacteria and nitrate testing in Georgia costs $50–$100 — among the lowest in the Southeast — while comprehensive panels including metals, pH, hardness, iron, manganese, and organic compounds run $150–$250. Properties in south Georgia's agricultural belt should test for nitrates and pesticides regularly, as row crop farming and poultry operations can contribute to groundwater contamination in the sandy Coastal Plain aquifers.
Georgia's geology creates distinct water quality profiles across the state. North Georgia wells drilled into crystalline bedrock may produce water with naturally elevated radon, iron, or manganese. The Piedmont's granite and gneiss formations can contribute to hard water and occasionally elevated uranium levels. The Coastal Plain sits atop the Floridan Aquifer, one of the most productive aquifer systems in the world, which generally provides high-quality water but can be vulnerable to saltwater intrusion near the coast. Homeowners in the Savannah area and coastal counties should test for chlorides if their wells are relatively shallow or located within a few miles of tidal waterways.
