What to know about Atlanta's water
Atlanta ranks #370 out of 378 cities in Georgia for water quality, placing it among the lowest-rated in the state.
The city draws from surface water sources, which are more susceptible to seasonal runoff and agricultural contamination, requiring extensive multi-barrier treatment including coagulation, filtration, and disinfection.
PFAS compounds were detected in testing, though levels remain within current EPA limits. Residents seeking extra precaution may consider an activated carbon or reverse osmosis filter.
Haloacetic acid (HAA5) levels were elevated at 48.7 µg/L in UCMR 4 testing, though below the 60 µg/L EPA limit. Activated carbon filtration can help reduce these disinfection byproducts.
Hexavalent chromium (chromium-6) was detected at 0.21 µg/L in UCMR 3 testing. While below California's 10 µg/L limit and with no federal MCL set, residents sensitive to this contaminant may consider reverse osmosis filtration.
As a major metropolitan system serving over 1.1M residents, Atlanta faces large-scale infrastructure challenges including aging pipes and the complexity of treating water across a vast distribution network.
The system has seen 9 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.

Where does Atlanta's water come from?
Atlanta's drinking water comes from surface water (rivers, lakes, or reservoirs), supplied by 10 water systems serving approximately 1,091,053 people. Surface water sources are more susceptible to contamination from runoff, industrial discharge, and algal blooms, requiring extensive treatment. Nearby water bodies include South River (river), Doolittle Creek (river), Shoal Creek (river), Chatt R (river), Rottenwood (river).
What Atlanta residents can do
Recommended: Activated carbon or reverse osmosis filter. This addresses the specific contaminants found in Atlanta's water.
Your water utility is required to publish an annual Consumer Confidence Report (CCR) with detailed testing results. Ask for the latest copy or check your utility's website.

Why does Atlanta have so many PFAS compounds in its water?
4 different PFAS "forever chemical" compounds were detected in Atlanta's water supply during UCMR 5 testing. PFAS contamination often originates from proximity to military installations (AFFF firefighting foam), airports, industrial manufacturing sites, or wastewater treatment facilities. While detected, current levels are within EPA limits. An activated carbon filter can further reduce exposure.
How does Atlanta's water compare to other cities?
Atlanta ranks #370 out of 378 cities in Georgia (better than 2% of state cities) and #15416 out of 15744 cities nationally (2th percentile). The grade of F reflects the combined assessment of violation history, lead and copper levels, PFAS contamination, and regulatory compliance.
