Important Health Information
This article provides general information about PFAS contamination. For specific health concerns, please consult with your healthcare provider or contact the Agency for Toxic Substances and Disease Registry (ATSDR).
If you live in Florida, you may have heard about PFAS contamination in drinking water. These synthetic chemicals, often called "forever chemicals," have become a significant public health topic as scientists learn more about their presence in water supplies and potential health effects.
In April 2024, the U.S. Environmental Protection Agency (EPA) established the first-ever national drinking water standards for PFAS, marking a significant step in addressing these contaminants. Understanding what PFAS are, where they come from, and how to reduce your exposure can help you make informed decisions about your family's drinking water.
What Are PFAS?
PFAS stands for per- and polyfluoroalkyl substances, a large group of synthetic chemicals that have been manufactured and used in various industries since the 1940s. There are thousands of different PFAS compounds, though researchers have primarily focused on a few key types:
PFOA (Perfluorooctanoic Acid)
Historically used in making Teflon and other non-stick coatings. Production phased out in the U.S. by 2015, but persists in the environment.
PFOS (Perfluorooctane Sulfonate)
Previously used in Scotchgard and firefighting foams. Phased out of production but remains widespread in the environment.
GenX (HFPO-DA)
A replacement chemical for PFOA, now also under EPA regulation. Used in some manufacturing processes and industrial applications.
Other PFAS
PFHxS, PFNA, PFBS, and thousands of other compounds with similar chemical structures, each with varying properties and uses.
PFAS are used in products designed to resist water, grease, and stains. Common applications include:
- Non-stick cookware (Teflon-coated pans)
- Water-resistant clothing and outdoor gear
- Stain-resistant carpets and upholstery
- Food packaging (microwave popcorn bags, fast food wrappers)
- Firefighting foam (AFFF) used at airports and military bases
- Some cosmetics and personal care products
- Industrial applications and manufacturing processes
Why Are They Called "Forever Chemicals"?
PFAS contain extremely strong carbon-fluorine bonds—among the strongest chemical bonds in organic chemistry. This molecular structure gives PFAS their useful properties (resisting heat, water, and oil), but it also means they:
Don't Break Down Naturally
PFAS persist in soil, water, and air for decades or longer. Unlike many other pollutants, they don't biodegrade through natural processes.
Accumulate in the Body
When ingested, PFAS bind to proteins in blood and can accumulate in organs. The body eliminates them very slowly, with half-lives measured in years for some compounds.
Move Through Water Systems
PFAS are highly mobile in water and can travel long distances from their original source, contaminating groundwater and drinking water supplies miles away.
According to the CDC, PFAS have been detected in the blood of 98% of Americans tested, indicating just how widespread these chemicals have become in our environment and daily lives.
PFAS Sources in Florida
Florida faces particular challenges with PFAS contamination due to several factors. The state's extensive military presence, numerous airports, and industrial facilities have contributed to PFAS entering water supplies. Additionally, Florida's porous limestone aquifers can allow contaminants to spread more easily through groundwater.
Major Sources of PFAS Contamination
Military Installations
Florida has over 20 major military bases where PFAS-containing firefighting foam (AFFF) has been used for decades. The Department of Defense has identified numerous sites with PFAS contamination.
- Naval Air Station Jacksonville
- Patrick Space Force Base
- Homestead Air Reserve Base
Airports
Commercial and regional airports use AFFF firefighting foam for fire suppression training and emergency response. Florida's many airports represent potential contamination sources.
- Miami International Airport
- Fort Lauderdale-Hollywood International
- Palm Beach International Airport
Industrial Facilities
Manufacturing facilities that use or produce PFAS-containing products can release these chemicals into local water systems through wastewater discharge or accidental releases.
- Chemical manufacturing plants
- Electronics and semiconductor facilities
- Textile and coating manufacturers
Other Sources
Additional pathways for PFAS to enter the environment and water supplies include:
- Landfills containing PFAS products
- Wastewater treatment plants
- Agricultural areas using biosolids
- Fire training facilities
Health Concerns
About This Information
The health effects described below are based on research studies compiled by the EPA, CDC, and ATSDR. Scientific understanding of PFAS health effects continues to evolve. This information is not medical advice—please consult healthcare professionals for personal health concerns.
Research on PFAS health effects is ongoing, and scientists continue to study how these chemicals affect human health. According to the EPA and CDC, exposure to certain PFAS at levels above the new drinking water standards over many years may be associated with:
Potential Health Effects Under Study
- Changes in cholesterol levels
- Changes in liver enzymes
- Decreased vaccine response in children
- Increased risk of high blood pressure during pregnancy
- Decreased infant birth weights
- Increased risk of kidney or testicular cancer
- Thyroid hormone disruption
- Effects on the immune system
It's important to note that the presence of PFAS in drinking water does not mean health problems will occur. Risk depends on factors including the specific PFAS compounds present, concentration levels, duration of exposure, and individual health factors. The new EPA standards are designed to protect public health with a margin of safety.
Who May Be More Vulnerable?
Some populations may be more sensitive to PFAS exposure, according to health agencies:
- Pregnant women and developing fetuses
- Nursing mothers and infants
- Young children
- Individuals with certain health conditions
If you fall into one of these categories and are concerned about PFAS exposure, consider speaking with your healthcare provider about your specific situation.
PFAS in South Florida Water
PFAS have been detected in water supplies throughout Florida, including South Florida. The extent of contamination varies by location and water source. Here's what we know about the current situation in the tri-county area.
The 2024 EPA Drinking Water Standards
The EPA's new Maximum Contaminant Levels (MCLs) for PFAS are:
| PFAS Compound | New EPA Limit | Notes |
|---|---|---|
| PFOA | 4 ppt | Individual limit |
| PFOS | 4 ppt | Individual limit |
| PFHxS, PFNA, HFPO-DA | 10 ppt each | Subject to Hazard Index |
| PFBS | 2000 ppt | Subject to Hazard Index |
| Mixture of 4+ PFAS | Hazard Index 1 | Combined assessment |
ppt = parts per trillion. To put this in perspective, 4 parts per trillion is equivalent to about 4 drops of water in 20 Olympic-sized swimming pools.
Florida Testing and Compliance
Water utilities across Florida are required to test for PFAS under the EPA's new regulations. The compliance timeline includes:
- 2024-2027: Utilities must conduct initial monitoring and testing
- By 2029: Systems must implement treatment if PFAS levels exceed limits
Many Florida utilities have already begun PFAS testing and are working to address contamination where found. You can check your utility's Consumer Confidence Report or contact them directly for PFAS testing results.
Checking Your Local Water
To learn about PFAS levels in your specific water supply:
- Review your utility's Annual Water Quality Report (Consumer Confidence Report), which must be published by July 1st each year
- Contact your water utility directly to request the most recent PFAS testing results
- Check the EPA's PFAS monitoring data at epa.gov/pfas
- Consider professional water testing for private wells or additional peace of mind

How to Reduce PFAS Exposure
If you're concerned about PFAS in your drinking water, there are effective steps you can take to reduce your exposure. The key is choosing filtration methods that are specifically designed to remove these persistent chemicals.
Filtration That Works
Not all water filters remove PFAS. When selecting a filtration system, look for NSF/ANSI certification specifically for PFAS reduction:
Reverse Osmosis (RO) Systems
Effectiveness: 90-99% PFAS removal
RO systems force water through a semi-permeable membrane that blocks most contaminants, including PFAS. They're highly effective but require installation and maintenance. Look for systems certified to NSF/ANSI Standard 58 for PFAS.
Activated Carbon Block Filters
Effectiveness: 70-95% PFAS removal (varies by design)
High-quality activated carbon block filters can effectively reduce PFAS when properly designed with sufficient contact time. Look for filters certified to NSF/ANSI Standard 53 specifically for PFAS reduction. Not all carbon filters are equal.
Ion Exchange Systems
Effectiveness: 90%+ PFAS removal
Specialized ion exchange resins can capture PFAS compounds effectively. These systems are often used at the municipal level but are also available for home use in some configurations.
Filters That DON'T Remove PFAS
Standard pitcher filters, most refrigerator filters, and basic faucet filters are generally NOT effective at removing PFAS unless specifically certified for PFAS reduction. Always check for NSF certification when PFAS removal is your goal.
Other Ways to Reduce PFAS Exposure
While drinking water is a significant potential source, you can also reduce PFAS exposure through other lifestyle choices:
- Choose cookware without non-stick coatings, or use ceramic or cast iron alternatives
- Avoid stain-resistant treatments on furniture and carpets when possible
- Check cosmetics and personal care products for PFAS ingredients (often listed as "fluoro" compounds)
- Reduce consumption of fast food, which may come in PFAS-treated packaging
- Choose fresh or home-cooked meals over heavily packaged foods when practical

Frequently Asked Questions
In April 2024, the EPA established the first-ever national drinking water standards for PFAS. The Maximum Contaminant Levels (MCLs) are 4 parts per trillion (ppt) for PFOA and PFOS individually, and a combined Hazard Index of 1 for a mixture of PFHxS, PFNA, HFPO-DA (GenX), and PFBS. Water utilities have until 2029 to comply with these standards.
Check your water utility's Consumer Confidence Report (CCR) or Annual Water Quality Report, which utilities must publish each year. You can also request PFAS-specific testing results from your utility. For private wells, consider professional laboratory testing, as home test kits for PFAS are limited in accuracy.
No, boiling water does not remove PFAS and may actually concentrate them as water evaporates. PFAS are extremely stable compounds that require specific filtration methods like reverse osmosis, activated carbon filtration, or ion exchange resins for effective removal.
Most basic pitcher filters and refrigerator filters are not certified to remove PFAS effectively. To remove PFAS, look for filters specifically certified to NSF/ANSI Standards 53 or 58 for PFAS reduction. Reverse osmosis systems and high-quality activated carbon block filters are generally most effective.
According to current research, PFAS are not easily absorbed through the skin, so showering in PFAS-contaminated water is considered low risk. The primary concern is ingestion through drinking water. However, if you have concerns, consult with your healthcare provider.
The "half-life" of different PFAS compounds in the human body varies significantly. PFOS has a half-life of about 5 years, while PFOA has a half-life of about 3-4 years. Shorter-chain PFAS compounds may be eliminated more quickly. This means reducing exposure can gradually lower blood levels over time.
