Georgia's diverse landscape-from the Blue Ridge Mountains in the north to the Coastal Plain in the south-creates varied groundwater conditions across the state. Private wells serve many households, particularly in rural areas and communities outside the reach of municipal water systems.
The Georgia Department of Public Health recommends testing for private wells but does not mandate it for routine ownership or property sales. Testing is the responsibility of the individual well owner, making it important to understand both what's recommended and what applies to your specific situation.
Georgia's regulatory framework focuses primarily on well construction, siting, and abandonment through the Water Well Standards Act. For ongoing water quality, the state takes a guidance-based approach: testing is recommended, not required, for most private domestic wells. However, certain regulated facilities-like wells serving public establishments under Memorandum of Understanding agreements-do face specific testing requirements.
Georgia does not have a general statewide mandate requiring private domestic well water testing for property transfers or routine ownership. The Department of Public Health says testing is recommended, leaving the decision in the hands of well owners.
The regulatory framework in Georgia focuses on well construction rather than ongoing water quality testing. The Water Well Standards legal framework addresses siting, construction, and abandonment-ensuring wells are properly built-but doesn't impose routine testing requirements on private homeowners.
There's an important exception for certain regulated facilities. Wells serving public facilities under Memorandum of Understanding (MOU) agreements with local health departments are required to meet specific testing requirements, including the W-33 test profile. This typically applies to facilities like small public water supplies, certain commercial operations, or institutions-not regular private homes.
Real estate transactions often involve testing anyway. While Georgia law doesn't require it, mortgage lenders frequently do-especially for FHA, VA, and USDA loans. Many buyers also request testing as part of their due diligence. If you're buying or selling, check with your lender about their requirements.
The baseline testing recommended everywhere applies in Georgia: total coliform bacteria and E. coli to check sanitary integrity, plus nitrates which pose health risks to infants and pregnant women. Annual testing for these parameters follows national public health recommendations.
Georgia's varied geology creates regional differences in water quality. The crystalline rock formations of North Georgia can produce different groundwater characteristics than the sandy aquifers of the Coastal Plain. Some areas may have naturally occurring iron, manganese, or other minerals that affect water quality-not necessarily harmful, but worth knowing about.
Radon in water can be a concern in some parts of Georgia, particularly in areas with granite bedrock in the Piedmont and Blue Ridge regions. Radon is a radioactive gas that can dissolve into groundwater and is worth testing for if you're in an affected area.
Consider your local conditions when deciding what to test beyond the basics. Near agricultural areas, additional nitrate vigilance makes sense. If you have older plumbing, test for lead. If you notice changes in taste, odor, or appearance, expand your testing to investigate the cause.

Well water testing costs in Georgia vary based on what you're testing for and which lab you use. Basic bacteria and nitrate tests are generally affordable. Adding metals, radon, or comprehensive panels increases the cost.
Georgia county health departments may offer well water testing or can direct you to certified labs in your area. Some counties have environmental health programs that provide testing services at reasonable rates. Check with your local county health department for what's available.
Turnaround time follows typical patterns: bacteria results within a few days (samples are time-sensitive and must reach the lab within 24-30 hours), chemical tests for nitrates and metals within 5-10 business days. Georgia's summer heat means paying extra attention to keeping bacteria samples cold during transport.
For real estate transactions, factor in adequate time for sample collection, lab analysis, and any needed follow-up. If results show issues requiring treatment or retesting, you'll need additional time before closing.
Georgia well owners can choose from certified laboratories, county health department programs, sampling services, and mail-in test kit providers. For accurate, defensible results-especially for real estate transactions-look for labs certified for drinking water analysis.
County health departments can be a valuable resource in Georgia. They may offer testing services, maintain lists of approved labs, or provide guidance on contaminants of concern in your area. Contact your local environmental health office as a starting point.
If you need testing for a regulated well (MOU facility, commercial use), make sure your lab can provide the specific test profile required-such as the W-33 panel. Not all labs offer all tests, so confirm capabilities before committing.
Treatment companies may offer testing, sometimes at reduced cost. While convenient for screening, remember their primary business is selling treatment equipment. If they recommend expensive systems based on their test, consider getting independent verification.
