Florida Residents Face Growing PFAS Threat as EPA Guidelines Evolve: Your Complete Guide to Home Water Protection
Florida’s pristine springs and groundwater sources are under siege from an invisible enemy: per- and polyfluoroalkyl substances (PFAS), commonly known as “forever chemicals.” As EPA announced final individual regulatory determinations for PFHxS, PFNA, and HFPO-DA, and final regulatory determination for mixtures containing two or more of these three PFAS and PFBS in April 2024, Florida families are grappling with new realities about their water safety.
Understanding the Latest EPA Guidelines
EPA established legally enforceable levels, called Maximum Contaminant Levels (MCLs), for six PFAS in drinking water: PFOA, PFOS, PFHxS, PFNA, and HFPO-DA as contaminants with individual MCLs, and PFAS mixtures containing at least two or more of PFHxS, PFNA, HFPO-DA, and PFBS using a Hazard Index MCL. The most significant development is an enforceable Maximum Contaminant Level (MCL) at 4.0 parts per trillion (ppt) for PFOA and PFOS, individually.
However, recent changes have created uncertainty. EPA plans to develop a rulemaking to provide additional time for compliance, including a proposal to extend the compliance date to 2031, giving water utilities more time to implement treatment solutions. Public water systems must monitor for these PFAS and have three years to complete initial monitoring (by 2027), followed by ongoing compliance monitoring. Water systems must also provide the public with information on the levels of these PFAS in their drinking water beginning in 2027.
Florida’s PFAS Contamination Reality
The Sunshine State faces significant PFAS challenges. Seven spring sites exceeded the EPA’s Drinking Water Maximum Contaminant Level of 4 parts-per-trillion all within 10 miles of each other, on the east coast of Florida near Deltona. Research from the University of Florida reveals that freshwater springs provide 90% of the drinking water to its inhabitants, making contamination particularly concerning.
Military installations have been significant sources of contamination. MacDill Air Force Base in Tampa also recorded in its groundwater 517,000 ppt of PFOS in 2018, along with 62,400 ppt of PFOA. Patrick Air Force Base in Brevard County was found to have substantial water contamination where PFAS-containing firefighting foam was used in hangars, fire stations and fire training areas.
Major water utilities are also affected. Tampa Bay Water, which supplies to Hillsborough, Pinellas, and Pasco counties, as well as the cities of Tampa, St. Petersburg, and New Port Richey, has also detected a slight exceedance of PFOS at 4.4 ppt in its Lithia Water Treatment Plant.
Health Risks and Why Action Matters
Very low doses of PFAS have been linked to suppression of the immune system. These chemicals harm development and the reproductive system, such as reduced birth weight and impacts on fertility; increase risk of certain cancers; and affect metabolism, such as changes in cholesterol and weight gain. PFAS are known as forever chemicals because they do not break down in the environment and build up in our blood and organs.
Effective Home Protection Solutions
Florida homeowners don’t have to wait for municipal solutions. Several proven technologies can effectively remove PFAS from home water supplies:
Reverse Osmosis Systems
Reverse osmosis uses energy to push water through a membrane with tiny pores. The membrane stops many contaminants while allowing water to pass through. The best way to filter PFAS from your water is an in-home reverse osmosis filter under your sink or at your tap.
Activated Carbon Filtration
Activated carbon treatment is the most studied treatment for PFAS removal. GAC can be 100 percent effective for a period of time, depending on the type of carbon used, the depth of the bed of carbon, flow rate of the water, the specific PFAS you need to remove, temperature, and the degree and type of organic matter as well as other contaminants.
Ion Exchange Systems
Ion exchange resins are like tiny powerful magnets that attract and hold the contaminated materials from passing through the water system. Negatively charged ions of PFAS are attracted to the positively charged anion resins.
Choosing the Right System
When selecting a filtration system, consumers should choose a water filtration device that is independently certified to remove that contaminant by a recognized lab. When purchasing home water treatment to address PFAS, look for products certified to NSF/ANSI 53 (for filters) or NSF/ANSI 58 (reverse osmosis).
Testing has shown remarkable results. Some of the filters did not achieve 100 percent reduction in PFAS measured in the water samples, they did eliminate 100 percent of PFOA and PFOS, two of the most notorious forever chemicals.
Professional Water Treatment in Florida
For comprehensive water safety solutions, many Florida residents turn to professional water treatment companies. Quality safe water of florida specializes in providing advanced filtration systems designed to address the unique water quality challenges facing Florida families. With expertise in PFAS removal technologies and a commitment to ensuring safe drinking water, professional installation ensures optimal performance and proper maintenance.
Taking Action Now
If you know or suspect PFAS are in your tap water, the best way to protect yourself is by using a filtration system at home. Don’t wait for regulatory compliance deadlines – reducing levels of PFAS in your water is an effective way to limit your exposure.
The evolving EPA guidelines and Florida’s documented contamination issues make home water protection more critical than ever. Whether through certified point-of-use filters, whole-house systems, or professional water treatment solutions, Florida families have effective options to safeguard their health against these persistent forever chemicals. The key is taking action now, rather than waiting for municipal systems to comply with federal regulations.
