You’ve probably heard the term “forever chemicals” in the news, and if you live in Tampa, you might be wondering whether they’re in your drinking water. The short answer is: it’s complicated, and that’s exactly why you should know what PFAS is, why it matters, and what Tampa families can do about it.
PFAS stands for per- and polyfluoroalkyl substances. They’re synthetic chemicals created for industrial and consumer products because they’re extremely stable—they resist heat, oil, and water. That makes them incredibly useful for manufacturing, but it also makes them nearly impossible for your body or the environment to break down. Once PFAS enters your system, it stays there. That’s why they’ve earned the nickname “forever chemicals.”
Where Does PFAS Come From?
PFAS is everywhere in modern life, and that’s a problem. These chemicals are used in:
- Non-stick cookware coatings (like Teflon)
- Water-resistant clothing and textiles
- Stain-resistant furniture treatments
- Food packaging (grease-resistant paper, pizza boxes)
- Aqueous film-forming foams (AFFF) used in firefighting
- Industrial manufacturing processes
- Dental floss and some toothpastes
When these products are manufactured, used, and eventually discarded, PFAS enters the environment. Industrial facilities release it into water systems. Firefighting foam spreads it across airports and military bases. Landfills leach it into groundwater. Over decades, PFAS has accumulated in drinking water supplies across the United States—including in Tampa’s regional water system.
Tampa Bay Water, which supplies drinking water to much of the Tampa Bay region, has been actively testing the local drinking water supply for PFAS as part of the EPA’s nationwide study. This testing is relatively new territory; the EPA only set the first-ever federal maximum contaminant levels for PFAS in 2024. Before that, there were no federal limits at all, despite PFAS being detected in drinking water across the country for years.
The Health Risks Nobody Should Ignore
Unlike some water contaminants that cause problems only at extremely high levels, PFAS is concerning even at low levels because it accumulates in your body over time. Studies have linked PFAS exposure to:
- Cancer – particularly thyroid and kidney cancer
- Liver damage – elevated liver enzymes, fatty liver disease
- Thyroid disease – disrupted thyroid hormone levels
- Immune system suppression – reduced vaccine effectiveness, increased infection risk
- High cholesterol – increased cardiovascular risk
- Developmental problems – lower birth weight, delayed puberty, reduced bone strength in children
- Reproductive issues – fertility problems, pregnancy complications
The scariest part? These effects don’t require massive exposure. Researchers have documented health risks at levels that the new EPA limits were set to address. In other words, the EPA’s 2024 limits acknowledge that PFAS is dangerous at concentrations that have already been detected in American drinking water supplies.
For Tampa families with young children, infants, or pregnant women, PFAS in drinking water is particularly concerning. Developing bodies are more vulnerable to endocrine-disrupting chemicals, and PFAS is specifically known to interfere with hormones that control growth and development.
Why Tampa’s Water Sources Are at Risk
Tampa’s drinking water comes from surface water sources (the Hillsborough River, Alafia River, Tampa Bypass Canal) and groundwater (the Floridan Aquifer). Both types of water sources are vulnerable to PFAS contamination.
Surface water accumulates PFAS from industrial runoff, firefighting foam used at nearby airports and military bases, and wastewater discharge. The Tampa Bay region has significant industrial activity and port operations, both of which can introduce PFAS into waterways.
Groundwater gets contaminated through landfill leachate, industrial disposal, and aquifer injection of treated wastewater. Florida’s porous limestone geology means contaminants move through groundwater relatively quickly, especially in the Tampa Bay area.
The fact that Tampa Bay Water is testing for PFAS is actually a good sign—it means the water system is aware of the problem and trying to understand the scope. However, testing is ongoing, and comprehensive results take time. In the meantime, families need to understand that PFAS exposure is a real possibility.
Conventional Water Treatment Doesn’t Remove PFAS
Here’s the critical issue: standard water treatment processes—chlorination, coagulation, and sand filtration—do not effectively remove PFAS. These chemicals are designed to resist degradation, so they pass right through conventional treatment systems.
Only two water treatment methods effectively remove PFAS:
- Activated carbon filtration – absorbs PFAS, but only works until the carbon is saturated
- Reverse osmosis – forces water through a membrane so fine that PFAS molecules cannot pass through
Most municipal water systems, including Tampa’s, use conventional treatment. That means even if Tampa Bay Water tests and detects PFAS, they may not have the infrastructure in place to remove it completely.
This is why many water quality experts recommend that consumers in areas with PFAS concerns use point-of-use treatment for drinking and cooking water. It’s the most practical way to ensure PFAS isn’t ending up in your body.
What Tampa Residents Are Doing
Informed families in Tampa, Brandon, Riverview, Wesley Chapel, Clearwater, St. Petersburg, Westchase, and Carrollwood are taking action. Many have switched to purified water delivery services that use reverse osmosis treatment specifically because it removes PFAS and other synthetic contaminants.
It’s not about panic or distrust of authorities. It’s about making an informed choice: If you know PFAS exists in your water, and you know it can accumulate in your body and affect your health, why wouldn’t you choose water that’s been treated to remove it?
The Real Cost of PFAS Exposure
When you think about the cost of drinking PFAS-contaminated water, it’s not just about the water itself. Long-term health effects—thyroid disease, cancer, developmental issues in children—come with medical costs, stress, and life changes. Prevention through clean water is considerably cheaper than treatment for PFAS-related illness.
What You Can Do Right Now
- Stop assuming municipal water treatment removes all dangerous contaminants – it doesn’t. Conventional treatment is designed for pathogens and some chemicals, not synthetic compounds like PFAS.
- Use reverse osmosis filtration for your drinking and cooking water – activated carbon helps but isn’t as thorough as RO for PFAS removal.
- Ask Tampa Bay Water for PFAS test results – public records about water quality should be available to you. Transparency matters.
- Consider drinking water delivery – it’s a straightforward way to eliminate the guesswork about what’s in your water.
- Stay informed – PFAS research is evolving, and new health effects continue to be discovered. The more you know, the better choices you can make for your family.
The Bottom Line on PFAS and Tampa Water
Forever chemicals are called that because they don’t go away. Once they’re in your water supply, your body, or the environment, they stay there indefinitely. The EPA’s 2024 acknowledgment of PFAS as a health threat means we’re finally catching up to what scientists have known for years: these chemicals matter, and exposure needs to be minimized.
Tampa’s water system is testing for PFAS, which is responsible. But testing alone doesn’t remove the chemicals. If you’re concerned about PFAS in your drinking water—and given what we know about health risks, you should be—you need to take additional steps to protect your family.
The most effective step? Making sure the water you drink has been treated with reverse osmosis to remove PFAS and the other contaminants that standard treatment leaves behind.
