In January 2026, Brevard County officials confirmed what water quality advocates had been watching for months: PFAS — per- and polyfluoroalkyl substances, better known as "forever chemicals" — had been detected above new federal limits in two of the county's three water treatment plant systems. Here's a clear-eyed look at what that means, who's affected, and what you can do right now.

What Are PFAS? (The Plain-English Version)

PFAS is an umbrella term for a family of more than 12,000 synthetic chemicals invented in the 1940s. They were revolutionary — they make surfaces nonstick, resist grease and water, and withstand extreme heat. You'll find them in everything from nonstick pans and waterproof jackets to food packaging, firefighting foam, and stain-resistant carpet.

The problem is encoded in their name: per- and poly-fluoroalkyl means they're built around carbon-fluorine bonds — among the strongest in chemistry. These chemicals don't break down in the environment. Or in your body. They accumulate over time, which is why researchers started calling them forever chemicals.

The two most studied PFAS compounds are PFOA (perfluorooctanoic acid, once used to make Teflon) and PFOS (perfluorooctane sulfonate, the key ingredient in Scotchgard and AFFF firefighting foam). Both are no longer manufactured in the U.S., but they persist in groundwater for decades.

Why This Is Happening in Brevard

Brevard County has a specific and well-documented source of PFAS contamination: Patrick Space Force Base (formerly Patrick Air Force Base) in Cocoa Beach. For decades, military bases nationwide used AFFF — aqueous film-forming foam — to fight jet fuel fires in training exercises and real emergencies. AFFF is saturated with PFAS, and when it's used outdoors, it soaks into the soil and migrates into groundwater.

The Space Coast's porous sandy soil and shallow water table create ideal conditions for PFAS to spread from source areas into local aquifers. Some of those aquifers feed public water supply wells.

Independent monitoring has also found PFAS compounds in the Indian River Lagoon, in fish tissue, and in alligators — reflecting how thoroughly these chemicals have worked their way through the ecosystem.

Which Brevard Water Systems Are Affected?

Brevard County Utilities operates three main water treatment systems. Recent testing — completed by consultants in March 2024 and again in late 2025 — found very different results at each:

  • Mims Water Treatment Plant (North Brevard): PFAS levels exceeding new EPA limits were found in source water. The Mims system serves Titusville and surrounding north county communities. This was the focus of early community concern.
  • Barefoot Bay Water Treatment Plant (South Brevard): Recent samples also showed PFAS above EPA limits. Barefoot Bay is an unincorporated retirement community in southern Brevard near Micco.
  • San Sebastian Woods Water Treatment Plant (South Brevard): The good news — San Sebastian showed no detectable PFAS in its source wells or treated water during the entire 2025 fiscal year. This system serves parts of south Brevard near the Indian River County line.

It's important to note: cities like Melbourne, Palm Bay, and Cocoa Beach operate their own water utilities separate from Brevard County Utilities. If you're served by a city system, contact your city water department directly for their PFAS testing results.

The New EPA Limits: What Changed in 2024

For most of PFAS history, there were no federal drinking water limits. That changed in April 2024, when the U.S. Environmental Protection Agency finalized the first-ever maximum contaminant levels (MCLs) for PFAS in drinking water:

  • PFOA: 4 parts per trillion (ppt)
  • PFOS: 4 parts per trillion (ppt)
  • Additional limits were set for PFHxS, PFNA, HFPO-DA (GenX), and PFBS mixtures

To put 4 parts per trillion in perspective: that's equivalent to four drops of water in 20 Olympic-sized swimming pools. The EPA set these limits this low because PFAS bioaccumulate in the body — even small daily doses add up over a lifetime of drinking water.

Water utilities have until 2027 to complete initial PFAS monitoring and until 2031 to install treatment systems if they exceed the MCLs. So while the problem is real, utilities are operating within a federally established compliance timeline — they're not ignoring the issue.

What Brevard County Is Doing About It

In January 2026, the Brevard County Commission held a public meeting specifically to discuss PFAS in the water supply. Commissioner Katie Delaney has been vocal about the need for both transparency and action. Key commitments from the county include:

  • Reverse osmosis (RO) treatment systems at affected water treatment plants. RO is the gold standard for PFAS removal — it forces water through a membrane that blocks PFAS molecules. The county expects this will take approximately two to three years to implement fully.
  • Increased transparency to customers about PFAS levels in their water, including more frequent public reporting of test results.
  • Continued quarterly monitoring to track levels at all well and treatment sites.

County documents show the county received a quarterly PFAS report in September 2024 with results and recommendations from its consultant, Jacobs Engineering. That report informed the commission's January 2026 discussions.

"We are working on a reverse osmosis system for our water facilities, and that will filter out the PFAS in this water. One glass of water isn't going to be a problem, but a lifetime of drinking this will cause problems." — Commissioner Katie Delaney, January 2026

How to Check Your Own Water Quality

Every public water utility is required to produce an annual Consumer Confidence Report (CCR) — also called a Water Quality Report — that lists detected contaminants and how they compare to federal limits. Here's how to find yours:

  • Brevard County Utilities customers: Visit brevardfl.gov/UtilitiesServices and look for the annual Water Quality Report, or call (321) 633-2000.
  • City water customers: Search "[your city name] water quality report [year]" or visit your city's utilities department website. Melbourne, Palm Bay, Titusville, and Cocoa all post their CCRs online.
  • Well water users: Private wells are not regulated by the EPA or state utilities rules. If you have a private well and you're in a PFAS-affected area (especially near the Mims area or Patrick Space Force Base), consider getting your well tested through a state-certified laboratory. Florida DEP maintains a list of certified labs at floridadep.gov.
  • National database: The EPA's Consumer Confidence Report database lets you search any public water system by ZIP code.

Home Filtration: What Actually Works for PFAS

Until county-level treatment is in place, some residents — especially those in the Mims and Barefoot Bay service areas — may want to add filtration at home. Not all filters remove PFAS. Here's what the science says works:

Reverse Osmosis (RO) — Most Effective (95%+ removal)
Under-sink RO systems force water through a semi-permeable membrane that physically blocks PFAS molecules. NSF/ANSI Standard 58 certification means the filter has been independently tested for contaminant removal. Good under-sink RO units cost $200–$600 installed. They require occasional filter and membrane replacements (every 1–3 years for membranes). Whole-house RO is effective but expensive ($3,000+).

Activated Carbon / Granular Activated Carbon (GAC) — Moderately Effective (70–90% removal)
High-quality activated carbon filters — including many pitcher-style filters like BRITA Longlast+ and Clearly Filtered — can significantly reduce PFAS, though not as completely as RO. Look for NSF/ANSI Standard 53 or 58 certification. Activated carbon filters are more affordable ($50–$200 for pitcher/faucet units) but must be replaced on schedule — a clogged filter can actually release captured PFAS back into water.

What Does NOT Remove PFAS: Standard carbon pitcher filters (like basic Brita), boiling water, and refrigerator filters are generally not effective against PFAS. Boiling actually concentrates PFAS by evaporating water while leaving contaminants behind.

If you buy a filter, look for the NSF certification mark. The NSF maintains a searchable database of certified products at nsf.org/certified-products.

Should You Be Worried? An Honest Assessment

This is the hardest question to answer without veering into either false reassurance or unnecessary panic. Here's the science-based perspective:

The risk is real, but not a sudden emergency. PFAS health risks — including associations with certain cancers, thyroid disease, immune effects, and reproductive issues — are linked to long-term, cumulative exposure. Drinking a glass of tap water today in Mims is not equivalent to drinking poison. The concern is about daily exposure over many years.

The levels matter. The EPA set limits at 4 ppt — extremely low — specifically to protect against lifetime exposure. Even at levels somewhat above this limit, the risk from a single year of exposure is not the same as the risk from decades.

Actions reduce risk. Installing an RO filter, using certified pitcher filters, or simply using filtered water for drinking and cooking (versus cleaning or bathing) meaningfully reduces PFAS intake. The risk from showering in PFAS-containing water is much lower than drinking it, because skin absorption of PFAS is minimal.

Children and pregnant women are higher priority. If you have young children or are pregnant, the precautionary argument for a point-of-use RO filter is strongest. The EPA limits were set with children in mind, and early-life PFAS exposure is an area of active research.

Bottom line: take it seriously, take practical steps, hold your utility accountable, but don't panic. The county is on a path to fix this — and you have tools to protect yourself in the meantime.

Official Resources

The Space Coast has spent decades coexisting with the aerospace industry and the environmental tradeoffs that come with it. PFAS is another chapter in that story — one where the community has both the right to accurate information and the power to push for better. Watch the commission meetings, read your water quality reports, and make the filter investment if you're in an affected service area. That's not fear; that's being informed.
