At a glance

Water test for a new wellNot required statewide

No statewide water test and no state permit for an individual household well. The Water Well Standards Act requires the well to be drilled by a licensed water well contractor to the state construction standards (grouted casing, 10 ft from property lines, 50 ft from septic tanks and 100 ft from drainfields), and the contractor must disinfect it and give you a well record. Several counties, mostly in north Georgia and around Atlanta, require a well permit and a bacteriological test through the county environmental health office before the well is used, so check with your county.

Water test when a home is soldNot required statewide

No statewide requirement. The seller's disclosure only says whether the property is on a well. FHA, VA and USDA loans normally require a bacteria, nitrate and lead sample from a certified lab before closing, and a few county health departments require a well inspection at transfer.

What the state recommends

The Department of Public Health and UGA Extension recommend testing a private well for coliform bacteria every year and running the UGA basic water test (pH, hardness, nitrate and about 20 metals including iron, manganese, lead, copper and arsenic) every two to three years. Add radon and uranium in the Piedmont and the mountains, sodium and chloride near the coast, and test again after flooding, well work or a change in taste, color or smell.

Free or low-cost testingAvailable

Every county has a UGA Cooperative Extension office that sells the UGA water test kits at cost: the basic chemistry test (W1) and the bacteria test (W33) run roughly $30 to $50 each, with results explained by the county agent. Extension and the county health departments also run periodic free or discounted testing days, and several county environmental health offices test bacteria for a small fee.

Well depth and water chemistry

Well depth and water chemistry in Grady County follow the rock underneath it. Typical wells here run 200 to 500 ft in the fractured granite and gneiss of the Piedmont and north Georgia mountains, where yields are modest; 100 to 400 ft in the Floridan and Claiborne aquifers of the Coastal Plain south of the fall line, deeper (400 to 800 ft) in the southwest; shallow surficial wells of 30 to 100 ft along the coast and in the flatwoods. Contaminants worth testing for in this part of Georgia include coliform bacteria (statewide, worst in shallow and older wells), acidic corrosive water that pulls lead and copper from plumbing (piedmont and mountains), iron and manganese (piedmont and coastal plain).
