Groundwater & Well Water in Georgia

Homeowners, farmers, and businesses throughout Georgia depend on groundwater for drinking water, irrigation, and industrial operations. With diverse aquifer systems ranging from the highly productive Floridan Aquifer in south Georgia to crystalline-rock aquifers in the Piedmont region, Georgia offers excellent groundwater resources. Whether you're drilling a new well, treating water quality issues, or maintaining an existing system, understanding Georgia's groundwater resources and finding qualified contractors is essential.

Groundwater Overview in Georgia

Georgia contains several major aquifer systems that supply water to millions of residents and support critical agricultural operations, particularly irrigation in the state's southern regions. Approximately 30% of Georgia's population relies on private wells for their water supply, making groundwater a vital resource for rural and suburban communities. The state's groundwater situation is shaped by its diverse geology, which ranges from coastal plains to mountain regions, each with distinct aquifer characteristics and water availability.

Average Well Depth in Georgia: 100-400 feet for most regions, with deeper zones in some areas reaching 500+ feet

Typical Drilling Cost: $15-$28 per foot (including labor and casing)

Key Challenge: PFAS contamination near military installations including Moody Air Force Base and Robins Air Force Base, plus naturally occurring arsenic in some Piedmont counties

The groundwater resources of Georgia vary significantly from region to region. In south Georgia, the Floridan Aquifer provides abundant, high-quality water at moderate depths. In central and north Georgia, crystalline-rock aquifers require deeper drilling but offer reliable supply. The state's groundwater is generally of good quality, though areas near military bases require testing due to PFAS contamination concerns, and some Piedmont counties experience naturally occurring arsenic.

Aquifer Systems in Georgia

Georgia is underlain by three major aquifer systems that vary significantly by region. Understanding which aquifers are present in your area is the first step in evaluating your groundwater potential and estimating drilling costs:

Floridan Aquifer System (South and Coastal Georgia): One of the world's most productive aquifer systems, the Floridan Aquifer underlies much of south Georgia and extends beneath northern Florida and South Carolina. This carbonate aquifer system is characterized by high productivity and generally excellent water quality. In Georgia, the Floridan Aquifer is found at depths ranging from 100-400 feet in coastal areas to 200-500 feet in inland locations. It is the primary water source for millions of residents in south Georgia and supports major agricultural irrigation operations. The Floridan's reliability and high yield make it the preferred groundwater source for large-capacity users in the region.

Crystalline-Rock Aquifers (Piedmont and North Georgia): Central and north Georgia are underlain by fractured crystalline rock aquifers developed in granite, gneiss, and similar rock formations. These aquifers are found at depths ranging from 100-500 feet, with most productive zones between 150-400 feet. While individual well yields are typically more modest than the Floridan Aquifer, crystalline-rock aquifers are reliable and widely used throughout the Piedmont region and north Georgia mountains. Water quality is typically excellent in these aquifers, though drilling requires specialized equipment designed for rock formations.

Brunswick Aquifer System (Coastal Plain, Southeast Georgia): The Brunswick Aquifer System underlies the southeastern coastal plain, including areas around Brunswick and the barrier islands. This system is found at depths of 100-300 feet and provides water for coastal communities and agriculture. The Brunswick system has good productivity and is important for the region's water supply, though saltwater intrusion in areas very close to the coast requires careful well location and management.

What Affects Well Drilling Cost in Georgia

The cost to drill a well in Georgia depends on several interconnected factors. Understanding these cost drivers helps homeowners and property managers budget appropriately and get accurate quotes from contractors:

  • Depth: Drilling typically costs $15-$28 per foot depending on local geology. South Georgia's Floridan Aquifer wells are often shallower (100-300 feet), while Piedmont wells may reach 200-500 feet. Deeper wells require more drilling time, more casing material, and additional equipment.
  • Rock formations: Drilling through crystalline rock in north and central Georgia requires more powerful equipment and specialized drilling techniques, increasing costs compared to softer soil drilling in south Georgia. Hard rock sections may cost $25-$35 per foot versus $12-$18 per foot in softer sedimentary zones.
  • Well diameter: Larger diameter wells cost more to drill and case. Most residential wells are 4-6 inches in diameter, with larger diameters needed for high-yield applications like irrigation.
  • Permits and testing: Georgia requires well drilling permits, electrical permits for pump installation, and water quality testing. The Georgia Environmental Protection Division (EPD) regulates well construction through the Rules for Safe Drinking Water. Permits and testing add $500-$2,000 to project costs.
  • Equipment and labor: Atlanta metro area contractors typically charge more than rural Georgia contractors. Specialized equipment for rock drilling costs more to mobilize and operate.
  • Pump and pressure tank: Pump systems range from $2,000-$6,000 depending on well depth and required flow rate. Deeper wells and higher flow requirements increase pump costs.
  • Site accessibility: Remote properties may require additional mobilization costs. Good road access reduces contractor overhead.
  • Water quality treatment: If testing reveals treatment needs (iron removal, softening, or PFAS treatment), treatment system costs add $2,000-$10,000.

Most Georgia homeowners can expect to invest $5,000-$18,000 for a complete well installation including drilling, casing, pump, pressure tank, permits, and water quality testing. Get quotes from 2-3 licensed contractors to compare costs and services in your area.

Georgia Groundwater Regulations & Permits

Drilling a well in Georgia requires permits and adherence to state water laws. The Georgia Environmental Protection Division (EPD) oversees groundwater resources, and regulations include well construction standards, water quality requirements, and water withdrawal permits in some areas. Non-compliance can result in fines or orders to abandon wells.

Key regulatory considerations:

  • Well drilling permits: Georgia EPD requires notification and compliance with well construction standards before drilling begins. Most counties require county permits as well. Applications must include property information and well specifications.
  • Safe drinking water standards: Georgia follows EPA Safe Drinking Water Act standards. Wells serving multiple families must meet stricter testing and treatment requirements than single-family residential wells.
  • Well construction standards: Georgia EPD Rules for Safe Drinking Water specify casing requirements, grouting standards, and construction depth standards. Wells must have sanitary seals and proper construction to prevent contamination.
  • Setback requirements: Wells must maintain minimum distances from septic systems (typically 50+ feet), property lines, animal confinement areas, petroleum storage, and other contamination sources.
  • Water quality testing and reporting: Initial water quality testing is required. Results must be reported to EPD for certain parameters. Additional testing may be required near military installations due to PFAS concerns.
  • Electrical permits: Pump installation requires separate electrical permits from local authorities. All electrical work must meet National Electrical Code standards.

Contact your county health department, EPD regional office, or local well drilling contractor for specific permit requirements in your area. Processing times typically range from 2-4 weeks.

Water Quality Considerations in Georgia

Georgia groundwater is generally of good quality, but several factors require attention depending on location:

  • Naturally occurring arsenic: Some Piedmont counties contain naturally occurring arsenic in groundwater. Wells in these areas require testing and may need treatment systems.
  • PFAS contamination: Areas near Moody Air Force Base (south Georgia), Robins Air Force Base (central Georgia), and other military installations may contain per- and polyfluoroalkyl substances (PFAS) from firefighting foam. Wells in these areas should be tested for PFAS compounds.
  • Iron and hardness: Many Georgia wells contain elevated iron and mineral content, particularly in the Piedmont region. Iron causes reddish staining and objectionable taste; hardness requires softening for some applications.
  • Coliform bacteria: Some wells in rural areas may have coliform contamination. Proper well construction and sanitary seals prevent bacterial contamination.
