The EPA's April 2024 PFAS final rule sets a Maximum Contaminant Level of 4 parts per trillion (ppt) for PFOA and PFOS, with utilities given until 2029 to comply. Several South Florida utilities reported PFAS detections in their 2024 Consumer Confidence Reports. Residents who want protection now can install a point-of-use system certified to NSF/ANSI 53 (P473) or NSF/ANSI 58 (P473).

What PFAS Are and Why They Persist
Per- and polyfluoroalkyl substances, almost always shortened to PFAS, are a family of thousands of synthetic chemicals first manufactured in the 1940s. They have been used in firefighting foam, nonstick coatings, waterproof fabrics, food packaging, and dozens of industrial processes. The carbon-fluorine bonds that make PFAS useful also make them extraordinarily stable, which is why journalists started calling them "forever chemicals." Once PFAS reach groundwater or a surface canal, they do not meaningfully break down on a human timescale.
That stability matters more in South Florida than it does in most of the country. The Biscayne Aquifer, which supplies drinking water for most of Miami-Dade and Broward residents, is shallow, porous, and recharges quickly from rainfall and canal infiltration. What lands on the ground in West Boca or western Palm Beach County can reach a wellfield in a matter of months, not decades. For a deeper look at how the regional plumbing works, see our guide on private well water in South Florida versus city supply.
The EPA's 2024 PFAS Drinking Water Rule
On April 10, 2024, the U.S. Environmental Protection Agency finalized the first national, legally enforceable drinking water standard for PFAS. The rule sets enforceable Maximum Contaminant Levels (MCLs) for six compounds and uses a Hazard Index approach when several appear together. The numbers are unusually low because the EPA concluded there is no known safe level of exposure to PFOA or PFOS.
- PFOA: 4 ppt MCL, with a non-enforceable health goal (MCLG) of zero.
- PFOS: 4 ppt MCL, with an MCLG of zero.
- PFNA, PFHxS, HFPO-DA (GenX): 10 ppt MCL each.
- PFBS plus the four above: covered by a Hazard Index of 1, calculated across mixtures.
Public water systems were required to start monitoring under the rule in 2024 and to publish results in their annual Consumer Confidence Reports. Systems that exceed an MCL must install treatment or provide an alternative supply by 2029. The full rule text is published on the EPA PFAS drinking water page.
Where South Florida Utilities Stand
Several large South Florida utilities reported PFAS detections in their 2024 CCRs. The detections vary widely by wellfield, season, and sampling method, so the most accurate read is always the utility's own published report rather than a third-party summary. If you live in Boca Raton, Boynton Beach, or Delray Beach (the heart of our service territory), pulling your 2024 CCR is a 15-minute task that will tell you more than any blog post can. Direct links to each utility's report:
- City of Boca Raton Utilities publishes its annual drinking water quality report on the Boca Raton Water Quality page. If you live anywhere from East Boca to West Boca, this is your utility. See also our local guide to reverse osmosis in Boca Raton.
- Palm Beach County Water Utilities Department publishes CCRs for unincorporated PBC and the Glades-area systems on the PBCWUD Water Quality page. Customers in Boynton, Delray, Wellington, and parts of Jupiter fall under this utility for at least some addresses.
- Broward County Water and Wastewater Services posts reports for its retail districts, and individual cities like Fort Lauderdale, Pompano Beach, and Hollywood publish their own. Start at the Broward County water quality page.
- Miami-Dade Water and Sewer Department publishes the regional CCR for most Miami-Dade customers at miamidade.gov/water.
We are deliberately not republishing specific ppt numbers in this post. Sampling results shift between annual reports, and an outdated number becomes misinformation fast. Pull the most recent CCR for your address, scan the PFAS row, and bring it with you to your free water test. If you would rather have a tech walk you through it, our water testing service does exactly that.
What the Health Research Actually Says
The EPA did not pick 4 ppt arbitrarily. The agency set the MCL at the lowest level that current EPA-approved laboratory methods can reliably quantify, because the underlying health goal (the MCLG) for PFOA and PFOS is zero. The supporting science is summarized in the EPA's health advisory documentation and in the U.S. Department of Health and Human Services ATSDR PFAS health effects page.
The strongest associations in the peer-reviewed literature involve elevated cholesterol, reduced antibody response to childhood vaccinations, certain cancers (notably kidney and testicular), thyroid dysfunction, and developmental effects in pregnancy. PFAS also bioaccumulate, which means the half-life in human blood is measured in years. Reducing exposure today still pays off, because every dose you avoid is one your body does not have to clear later.
Home Filtration Options That Actually Reduce PFAS
Most pitcher filters and refrigerator filters are not certified for PFAS reduction. The two NSF/ANSI standards that matter for residential PFAS removal are NSF/ANSI 53 with the P473 designation (carbon-block systems certified for PFOA/PFOS reduction) and NSF/ANSI 58 with the P473 designation (reverse osmosis systems certified for PFOA/PFOS reduction). Always look for the P473 suffix on the listing, not just "NSF 53" or "NSF 58" in marketing copy. NSF publishes a searchable database at info.nsf.org/Certified/dwtu.
The three technologies that actually work at a home scale:
- Reverse osmosis (RO): Pushes water through a semi-permeable membrane that physically excludes the PFAS molecule. Independent NSF testing routinely shows greater than 95 percent reduction for PFOA and PFOS when the system carries the P473 listing. See our reverse osmosis service overview for what we install in South Florida homes.
- High-contact-time activated carbon: Certain large carbon-block systems certified to NSF/ANSI 53 (P473) can reduce PFOA and PFOS. These are the systems you want at the kitchen tap if RO is not a good fit, for example in a rental where drilling under the sink is off the table.
- Whole-home pre-treatment plus point-of-use polish: For homes also dealing with hardness, chloramines, or iron, the cost- effective build is a whole-home filtration system to protect plumbing and a P473-certified RO at the kitchen sink for drinking and cooking water.
Recommended Method: Match Your Concern to a System
Use the matrix below as a starting point. The right system depends on your address, your CCR, and how you actually use water at home, which is what we work through during a free in-home test.
| Your concern | Recommended system | Typical capacity |
|---|---|---|
| PFAS at the drinking tap only | P473-certified reverse osmosis | 50–100 GPD under the sink |
| PFAS plus chloramine taste and odor | Catalytic carbon pre-filter into RO | 75 GPD RO with 2.5-gal tank |
| PFAS plus hard water (scale, spotting, dry skin) | Water softener plus point-of-use RO | 32k–48k grain softener, 75 GPD RO |
| Whole-home protection (showers, laundry, appliances) | Whole-home carbon filtration plus RO | 10–15 GPM whole-home throughput |
| Private well west of the Turnpike | Well water treatment with lab test for PFAS first | Sized after lab results |

Call a Professional If Any of These Apply
PFAS is solvable at a home scale, but a few situations are not DIY territory. Talk to a licensed water treatment installer (us or otherwise) if any of the following describes your house.
- Your address sits near a known PFAS source such as a former firefighting training site, a regional airport like Boca Raton Airport or Palm Beach International, or a military installation.
- Your CCR shows the Hazard Index exceeding 1, or shows any single PFAS compound above the EPA MCL, even in one quarterly sample.
- You are on a private well in western Palm Beach or Broward County and have never had a lab PFAS test, which the EPA rule does not cover for private wells.
- Someone in the household is pregnant, breastfeeding, or immunocompromised, where the margin for error on exposure is smaller.
- You already installed a generic carbon filter and want to confirm it is actually certified for PFAS reduction (most are not).
- Your home has galvanized or lead-jointed plumbing where filter placement and bypass design matter for the whole-house plan.
- You are buying or selling a home in the area and need a third-party water-quality letter for closing.

What Treatment in 2026 Looks Like in South Florida
The 2024 EPA rule gives utilities until 2029 to bring detections below the MCL. Several South Florida systems are already piloting granular activated carbon (GAC) and ion-exchange treatment at the plant level, funded in part through the federal Drinking Water State Revolving Fund Emerging Contaminants grants. That is good news. It also means rate increases are coming, because PFAS treatment at the wellfield is expensive.
For the next three years, point-of-use treatment is the fastest path to a clean glass of water at your specific kitchen sink. The math is simple. A certified RO replaces roughly 1,000 single-use bottles per year per household and removes far more than PFAS, including most of what your CCR's contaminant table lists. For neighbors who want a deeper read, the rest of our water quality blog covers the regional picture in more detail, and the frequently asked questions page answers most of the install-day questions we get.
Frequently Asked Questions
Is South Florida tap water safe to drink in 2026?
Treated municipal water in South Florida meets every current EPA and Florida DEP enforceable standard, including disinfection and microbial limits. PFAS is the open question. Some utilities report detections below the MCL, others have already exceeded it in at least one sample. Pulling your most recent CCR is the only address-specific answer.
Will boiling water remove PFAS?
No. Boiling concentrates PFAS rather than removing them, because the chemicals do not evaporate at water's boiling point. The only proven home methods are reverse osmosis or a carbon-block filter carrying the NSF/ANSI 53 P473 listing. A standard refrigerator filter or pitcher will not reliably reduce PFAS unless its certification explicitly says so.
How much does a PFAS-rated system cost in South Florida?
A point-of-use reverse osmosis system installed under the kitchen sink typically runs in the low four figures installed, depending on tank size, faucet, and any pre-treatment. Whole-home builds vary more. We'll quote your home after the free water test and review financing options if it helps spread the cost.
Do I need to test my well for PFAS in Palm Beach County?
If your home is on a private well, especially west of Florida's Turnpike or near an airport or industrial site, a one-time accredited lab test for the EPA's six regulated PFAS is worth the cost. The federal rule does not cover private wells, so the responsibility defaults to the homeowner. We coordinate the lab sample as part of our water testing service.
Does a water softener remove PFAS?
No, not on its own. Ion-exchange softeners are designed to capture calcium and magnesium, not PFAS. The right pairing for a South Florida home with both hard water and PFAS concerns is a softener for the whole house plus a P473-certified RO at the kitchen sink. The two systems complement each other and protect different things.
Where can I check which utility serves my address?
Most South Florida utilities have a service-area map on their public site, or your monthly bill identifies the provider. If you are not sure, run your address through our water checker and we'll match it to the correct CCR. You can also browse our service area page for the cities and counties we cover daily.
