EPA PFAS Standards (2024)
In April 2024, the EPA finalized Maximum Contaminant Levels (MCLs) for six PFAS compounds. Water systems must comply by 2029.
| Compound | MCL |
|---|---|
| PFOA | 4 ppt |
| PFOS | 4 ppt |
| PFNA | 10 ppt |
| PFHxS | 10 ppt |
| HFPO DA_GenX | 10 ppt |

Health Effects of PFAS Exposure
Cancer Risk
PFOA and PFOS are associated with kidney, testicular, and other cancers
Thyroid Disruption
PFAS can interfere with thyroid hormone function
Immune Effects
Reduced vaccine response and immune system impairment in children
Reproductive Harm
Linked to pregnancy complications and reduced fertility
Liver Damage
Elevated liver enzymes and liver disease risk
Developmental Effects
Harm to fetal development and child growth
Frequently Asked Questions
Does Georgia have PFAS in the water?
Yes. Georgia has a 34.3% PFAS detection rate across 286 tested public water systems, according to EPA UCMR 5 data. This means 98 systems detected at least one PFAS compound. The national average detection rate is 34.4%, so Georgia is 0.1 percentage points below average.
How bad is PFAS contamination in Georgia?
Georgia's PFAS contamination is rated moderate severity. The maximum recorded PFAS level is 45 ppt, compared to the EPA MCL of 4 ppt for PFOA and PFOS. 18 systems exceed the EPA MCL, representing 6.3% of tested systems. 127 PFAS detections referenced in state data; significant industrial contamination
What can I do to reduce PFAS exposure in Georgia?
The most effective options are reverse osmosis (RO) filtration systems, which remove up to 90-95% of PFAS, and granular activated carbon (GAC) filters certified under NSF/ANSI Standard 58 or 62. Standard pitcher filters provide limited protection. Contact your water utility to request PFAS test results, or check the EPA's UCMR 5 data portal for your system's specific readings.
What is the EPA MCL for PFAS?
The EPA finalized Maximum Contaminant Levels (MCLs) for PFAS in April 2024: 4 parts per trillion (ppt) each for PFOA and PFOS, and 10 ppt each for PFNA, PFHxS, and HFPO-DA (GenX). Water systems have until 2029 to comply. These are the strictest PFAS drinking water standards in the world.
National Comparison
Reduce PFAS Exposure
