PFAS in Florida (FL): 309 ZIPs Exceed Limits
620 ZIPs tested · 309 exceeding limits (50%) · Updated 2026-05-31
Data: EPA UCMR 3/5, SDWIS, ECHO, DOD Last verified: 2026-05-31
Florida has critical PFAS contamination with 50% of tested ZIP codes exceeding federal limits. 309 ZIP codes show PFAS levels above EPA thresholds. Residents in affected areas should consider water filtration systems rated for PFAS removal.
PFAS Contamination Overview
620 ZIP codes in Florida have been tested for PFAS (per- and polyfluoroalkyl substances). Of those, 309 (50%) exceed federal EPA limits set in 2024.
An additional 826 ZIP codes in Florida have not been tested for PFAS, representing potential undetected contamination.

PFAS Contamination Sources
Military Bases
52 military bases in Florida are linked to PFAS contamination, primarily from the use of aqueous film-forming foam (AFFF) in firefighting training exercises. These foams contain high concentrations of PFOS and PFOA.
Superfund Sites
Florida has 53 Superfund sites that may contribute to PFAS contamination through industrial waste, landfill leachate, and chemical manufacturing.
Other Sources
Beyond military and Superfund sites, PFAS contamination in Florida also stems from:
- Industrial facilities and manufacturing plants
- Airports (AFFF use in fire training)
- Wastewater treatment plants
- Landfills (leachate from consumer products)
- Agricultural use of biosolids
What You Can Do
If your ZIP code shows PFAS contamination:
- Test your water — request a PFAS test from your utility or use a certified lab ($200-$400)
- Install filtration — reverse osmosis (RO) or granular activated carbon (GAC) systems remove 90%+ of PFAS
- Check NSF certification — look for NSF/ANSI 53 or 58 certification on filters
- Monitor utility reports — public water systems must test and report PFAS levels by 2029
- Avoid contaminated sources — if on a private well near a known contamination source, test regularly
Data Sources
- PFAS detections: EPA Unregulated Contaminant Monitoring Rule (UCMR 3/5)
- Military bases: Department of Defense PFAS Task Force
- Superfund sites: EPA Superfund PFAS

Is there PFAS contamination in Florida?
620 ZIP codes in Florida have been tested for PFAS (per- and polyfluoroalkyl substances). 309 ZIP codes (50%) exceed federal EPA limits. PFAS contamination comes from military bases, industrial sites, and consumer products.
How many ZIP codes in Florida exceed PFAS limits?
309 of 620 tested ZIP codes in Florida exceed EPA PFAS limits, representing 50% of tested areas. 826 ZIP codes remain untested.
What are the sources of PFAS in Florida?
Major PFAS sources in Florida include 52 military bases that used AFFF firefighting foam, 53 Superfund sites, industrial facilities, airports, and wastewater treatment plants.
How can I remove PFAS from my drinking water?
The most effective home filtration methods for PFAS removal are reverse osmosis (RO) systems and granular activated carbon (GAC) filters. NSF/ANSI 53 or 58 certified filters can reduce PFAS by 90%+. Pitcher filters are less effective than point-of-use RO systems.
What is the EPA limit for PFAS in drinking water?
The EPA finalized national drinking water standards in 2024: 4 parts per trillion (ppt) for PFOA and PFOS individually, and a Hazard Index for mixtures of PFHxS, PFNA, HFPO-DA, and PFBS. Public water systems must comply by 2029.
