Well water testing analyzes your private well water for contaminants including bacteria, nitrates, heavy metals, pH levels, and other substances that can affect health and taste. The EPA does not regulate private wells — the responsibility falls entirely on the homeowner. An estimated 23% of private wells have at least one contaminant exceeding health-based standards according to the USGS. Annual testing is recommended at minimum, with additional testing after flooding, nearby land use changes, or if you notice changes in taste, color, or odor. Basic tests cover coliform bacteria and nitrates — the two most common and dangerous contaminants in well water. Comprehensive panels add testing for lead, arsenic, manganese, iron, hardness, pH, total dissolved solids, volatile organic compounds, and pesticides depending on your region and local geology. Results typically take 5-14 business days from a certified laboratory. If contaminants are found, treatment options range from simple point-of-use filters to whole-house treatment systems depending on what is detected and at what concentration.

Georgia Regulations for Well Water Testing

Georgia regulates septic systems through the Georgia Department of Public Health (DPH), Environmental Health Section. County Boards of Health issue permits and conduct inspections for all on-site sewage management systems. Georgia's regulations are found in the Manual for On-Site Sewage Management Systems, last updated in 2019. All new installations require a site evaluation by a county environmental health specialist, including soil analysis and a percolation test. The state requires a minimum lot size of 21,780 square feet (half acre) for properties with both a well and septic system. Systems must maintain setbacks of 100 feet from wells, 50 feet from surface water, and 10 feet from property lines. Georgia requires septic inspections at time of property transfer in the 13-county metro Atlanta area. Advanced systems require maintenance contracts filed with the county health department.

Licensing Requirements

Georgia requires all septic system installers to hold a valid Installer's Permit issued by the County Board of Health. Master Plumber or Journeyman Plumber licenses are required for connecting household plumbing to the septic system. Septic tank pumpers must obtain a Pumper's Permit and maintain records of all tanks serviced, including volumes and disposal locations. The state mandates liability insurance for all permitted installers and pumpers.

Environmental Considerations

Georgia's Piedmont region — stretching from metro Atlanta through middle Georgia — features dense red clay soils with notoriously poor percolation rates, making conventional drain fields challenging. Many properties require engineered alternatives. The Coastal Plain in southern Georgia has sandier soils and higher water tables. Metro Atlanta's rapid suburban expansion into Cherokee, Forsyth, Gwinnett, and Jackson counties has created enormous demand for new septic installations in exurban developments that outpace sewer infrastructure. Mountain counties in north Georgia have shallow bedrock similar to western North Carolina.

Signs You Need Well Water Testing

Annual testing is overdue — all private wells should be tested at least yearly
Water has a new or unusual taste, odor, or color
Recent flooding or heavy rainfall near the well
Nearby construction, agriculture, or land use changes
Household members experiencing unexplained gastrointestinal illness
Buying or selling a property with a private well

The Well Water Testing Process

1 Contact a certified water testing laboratory or local health department for test kits
2 Collect water samples following the lab's instructions for each test type
3 Submit samples to the lab within the required holding time (usually 24-48 hours)
4 Lab analyzes samples and compares results to EPA health-based standards
5 Receive a detailed report showing contaminant levels and whether they exceed guidelines
6 If issues are found, consult with a water treatment professional for remediation options

Frequently Asked Questions — Well Water Testing in Georgia

How often should I test my well water?

At minimum, test annually for coliform bacteria and nitrates. Test more frequently if you have infants or elderly household members, notice changes in taste or appearance, have had past contamination, or experience flooding near your well. Real estate transactions typically require a comprehensive panel within 90 days of closing.

What does a basic well water test cover?

A basic test typically covers total coliform bacteria, E. coli, nitrates, and pH. These are the most common and health-critical contaminants in private wells. A comprehensive panel adds heavy metals (lead, arsenic, manganese), hardness, iron, sulfate, total dissolved solids, and sometimes pesticides or volatile organic compounds depending on your region.

How much does well water testing cost?

Basic bacteria and nitrate testing runs $50-$100 through your county health department or a certified lab. Comprehensive panels testing for 20-50+ parameters cost $150-$500. Specialty testing for radon, pesticides, or volatile organic compounds may add $50-$200 per parameter. Many county health departments offer free or subsidized basic testing.
