Well Water Testing Savannah Georgia Area

Well water testing Savannah Georgia homeowners need addresses different threats than inland Georgia. The Savannah metropolitan area — spanning Chatham, Effingham, and Bryan counties — sits on the productive Floridan aquifer, which provides generally good water quality. But three specific risks make testing essential: saltwater intrusion threatening coastal wells, PFAS contamination from Hunter Army Airfield and Fort Stewart, and naturally occurring minerals at levels that affect taste and plumbing.

Bryan County is the fastest-growing county in Georgia at 30.1% population increase since 2020, driven partly by the Hyundai megasite and Savannah spillover. That growth puts more private wells online every year, and many new well owners have never dealt with private water supply issues before. Whether you have had your well for decades or just drilled one, periodic testing is the only way to confirm your water is safe.

Well Water Testing Savannah Georgia: What to Test For

The Savannah area's coastal geology and military history create a specific set of testing priorities. Here is what well water testing Savannah Georgia residents should include in their testing panel.

ContaminantWhy It Matters in Savannah AreaRecommended Frequency
Coliform bacteriaHigh water tables increase contamination riskAnnually
NitratesAgricultural activity in Bryan and Effingham countiesAnnually
Chloride/conductivityIndicator of saltwater intrusion in coastal wellsEvery 2-3 years
PFASHunter AAF and Fort Stewart contaminationOnce, then every 3-5 years
Iron/manganeseCommon in Floridan aquifer, causes stainingEvery 3-5 years
HardnessLimestone aquifer produces moderately hard waterOnce at well installation

Savannah Well Water Quality: Saltwater Intrusion

Saltwater intrusion is the signature Savannah well water quality concern that inland Georgia does not face. The Floridan aquifer along the coast is in hydraulic connection with the Atlantic Ocean. Heavy pumping — from municipalities, industry, and thousands of private wells — lowers the freshwater pressure that keeps saltwater at bay.

Signs of saltwater intrusion include increasing chloride levels in your well water, a slightly salty or brackish taste, and corrosion of plumbing fixtures. The process is gradual — you may not notice a taste change until chloride levels are well above the aesthetic threshold of 250 mg/L.

Chatham County wells closest to the coast and the Savannah River are at highest risk. Wells on Tybee Island and in the eastern portions of Savannah face the most significant intrusion pressure. Testing chloride levels every 2 to 3 years provides early warning before the water becomes unusable.

If saltwater intrusion affects your well, treatment options include reverse osmosis ($3,000 to $6,000 for a whole-house system) or drilling a new well at a different depth or location. In some cases, the only viable option is connecting to municipal water. The Savannah area's public water infrastructure is extensive but does not reach all rural properties in Bryan and Effingham counties.

Chatham County Well Testing: PFAS Near Military Sites

PFAS contamination adds urgency to chatham county well testing for properties near Hunter Army Airfield (Chatham County) and Fort Stewart (Liberty County, adjacent to Bryan County). Both installations used PFAS-containing firefighting foam (AFFF) for decades. The DoD has both sites under investigation, with remedial work ongoing.

Private wells within 3 miles of either installation should be tested for PFAS as a priority. The EPA's maximum contaminant level is 4 parts per trillion for PFOA and PFOS — a level so low that only certified labs using EPA Method 533 or 537.1 can detect it accurately.

PFAS testing costs $200 to $500 for a comprehensive panel. If your well tests positive above EPA limits, granular activated carbon (GAC) filtration ($1,500 to $4,000 whole-house) or reverse osmosis ($200 to $600 point-of-use) removes PFAS effectively. For detailed treatment options, see our PFAS in Georgia well water testing guide.

Coastal Georgia Well Water: Unique Considerations

Beyond Savannah proper, coastal georgia well water across Bryan, Effingham, Glynn, and Camden counties shares several characteristics and challenges.

High water tables. Coastal Georgia's flat terrain and proximity to sea level create shallow water tables, sometimes within 3 to 10 feet of the surface. This affects both well construction (requiring deeper casing to avoid surface contamination) and septic systems (requiring elevated or mound-style designs). The interaction between shallow wells and nearby septic drain fields is a real contamination risk.

Floridan aquifer quality. The aquifer generally provides clean, reliable water with moderate hardness. Iron and manganese are the most common aesthetic issues — staining fixtures, laundry, and producing a metallic taste. Treatment with whole-house iron filtration ($800 to $2,500) resolves these problems effectively.

Rapid development. Bryan County's 30.1% growth rate and Effingham County's steady expansion are putting hundreds of new wells online. New well owners should test within the first month of operation and establish an annual testing routine. Georgia requires initial chlorination to at least 50 ppm before the well is put into service.

Frequently Asked Questions

Is Savannah well water safe to drink?

Most Savannah-area wells drawing from the Floridan aquifer produce safe water, but you cannot confirm this without testing. Saltwater intrusion, PFAS from military sites, and naturally occurring minerals can all affect water quality. Annual bacteria and nitrate testing is the minimum. Add PFAS testing if you live near Hunter AAF or Fort Stewart.

How deep are wells in the Savannah area?

Residential wells in the Savannah area typically range from 60 to 200 feet, drawing from the Upper Floridan aquifer. Deeper wells (200 to 400 feet) access the Lower Floridan aquifer, which generally has better water quality but higher drilling costs. Your well driller recommends the optimal depth based on local hydrogeology and neighboring well data.

Does Bryan County require well water testing?

Georgia does not require periodic well water testing for existing private wells. However, most mortgage lenders require bacteria and nitrate testing at the time of property sale. Bryan County's health department offers basic testing services. Given the county's rapid growth and proximity to Fort Stewart, testing is strongly recommended even when not required.

What causes the sulfur smell in Savannah area well water?

Hydrogen sulfide gas produces the rotten egg odor sometimes found in Floridan aquifer wells. It forms when sulfate-reducing bacteria interact with naturally occurring sulfate in the limestone aquifer. While unpleasant, it is not typically a health hazard at the levels found in Georgia. Aeration systems or oxidizing filters ($500 to $2,000) effectively eliminate the odor.
