TLDR:
Is PFAS in Water Putting Your Family at Risk?
- PFAS (polyfluoroalkyl substances) are toxic “forever chemicals” found in tap water across the U.S.
- Exposure to PFOA and PFOS may increase the risk of cancer, hormone issues, and immune problems.
- PFAS enter public water systems through industrial waste, firefighting foam, and runoff.
- Many utilities have tested for PFAS, but not all homes are covered—especially private wells.
- You can test your water for PFAS through certified labs or check local reports.
- The EPA has proposed strict new drinking water standards to regulate PFAS exposure.
- Reverse osmosis and activated carbon filters are the most effective ways to remove PFAS.
- Choosing the right PFAS water filter can protect your family’s health for years to come.
Bottom line: PFAS in drinking water is a serious public health concern. Be proactive—test your water, understand the levels of PFAS, and install a certified filter.
When you pour yourself a glass of water from the tap, you expect it to be safe. But in recent years, scientists and public health officials have raised serious concerns about PFAS in water—a group of man-made chemicals that may be lingering in your drinking water without your knowledge.
What is PFAS in water? In this article, we’ll break down everything you need to know about polyfluoroalkyl substances (PFAS)—also known as “forever chemicals in water”—and what you can do to protect your family.
What Is PFAS in Water?
PFAS stands for polyfluoroalkyl substances, a group of over 12,000 synthetic chemicals used since the 1940s in products like nonstick cookware, firefighting foam, stain-resistant fabrics, and food packaging. These chemicals are designed to resist heat, water, and oil, qualities that also make them extremely persistent in the environment.
When these chemicals get into our public water systems, they can remain for decades. They don’t break down easily, and they can accumulate in the human body over time.
Some of the most studied types of PFAS include PFOA (perfluorooctanoic acid) and PFOS (perfluorooctane sulfonic acid), both of which have been linked to health risks.
How Do PFAS Get into Drinking Water?
PFAS often enter drinking water systems through industrial discharge, landfills, wastewater treatment plants, and firefighting training sites. Once they seep into groundwater or reservoirs, they can easily make their way into your tap water, especially if your home relies on public water systems or shallow wells near contaminated areas.
Many water sources in the United States have already tested for PFAS, revealing contamination levels that have prompted federal and state responses.
The Health Impact: Why PFAS Are a Public Health Concern
Exposure to even small levels of PFAS over time may pose serious risks. According to the Environmental Protection Agency (EPA) and independent studies, long-term exposure to certain PFAS has been associated with:
- Increased risk of cancer (especially kidney and testicular)
- Liver and thyroid problems
- Hormonal disruptions
- Increased cholesterol levels
- Immune system suppression
- Low birth weights in infants
Because these chemicals are so persistent, they’ve earned the nickname “forever chemicals in water.” Once they’re in your body, it can take years for them to break down.
How Do I Test My Water for PFAS?
Most public water systems are now required to monitor specific PFAS compounds under EPA guidelines, but not all communities have completed testing. Smaller utilities and private wells may not test at all.
To find out if your area has been tested, you can:
- Check your local water quality report (usually available online or by request)
- Search the EPA’s PFAS data map to see if your region has reported contamination
- Hire a certified lab to independently measure PFAS in your home’s drinking water
Drinking Water Standards and PFAS Regulation
Historically, there were no national drinking water standards for PFAS in the U.S. But in 2023, the EPA proposed enforceable limits for six PFAS chemicals, including PFOA and PFOS, at 4 parts per trillion (ppt).
These are some of the strictest regulations for any contaminant, reflecting growing awareness of the dangers these chemicals pose. These limits are expected to become law soon, which will require many utilities to upgrade their filtration systems.
Still, it may take years before all systems are compliant, leaving families exposed in the meantime.
How to Remove PFAS from Drinking Water
Once you’ve determined your water may be affected, the next question is: How do I actually remove PFAS from drinking water?
Here are the most effective solutions:
1. Activated Carbon Filters
Some water filters use activated carbon, which can absorb certain PFAS compounds. These are typically available in countertop pitchers, faucet attachments, or under-sink models. However, they may need frequent replacement and are less effective against shorter-chain PFAS chemicals.
2. Reverse Osmosis (RO) Systems
A reverse osmosis system is currently the gold standard for removing PFAS from water. These systems force water through a semipermeable membrane, blocking contaminants like PFAS, lead, arsenic, and more. They are installed under your sink and provide clean, filtered water for drinking and cooking.
RO systems are proven to reduce PFOA and PFOS to non-detectable levels when properly maintained.
3. Whole-Home Filtration Systems
If you’re worried about PFAS water exposure through bathing or brushing your teeth, a whole-house filtration system may be the best solution. These systems treat all incoming water before it flows through your pipes. Look for systems certified for PFAS testing and reduction.
Should You Be Concerned?
If PFAS are found in your water, don’t panic—but don’t ignore it either. The risk depends on the levels of PFAS, your length of exposure, and your overall health. Still, these substances are linked to public health concerns serious enough to warrant federal regulation.
Here are some proactive steps you can take:
- Stay informed about your local water system’s PFAS testing efforts
- Use certified water filters to reduce exposure
- Ask your utility if your area has tested for PFAS
- Encourage local officials to follow drinking water standards for regulated PFAS
- If using a private well, get it tested for PFAS through an EPA-certified lab
The Bottom Line: Prioritize Your Family’s Water Safety
The presence of PFAS in drinking water is a growing concern that families can no longer afford to ignore.
While the science is still evolving, the current evidence suggests that limiting your exposure is a smart and proactive move—especially for households with young children, pregnant women, or individuals with chronic health conditions.
Fortunately, there are solutions. With the right information, testing, and filtration system, you can confidently reduce your risk and protect your family from polyfluoroalkyl substances (PFAS) and other harmful forever chemicals in water.
If you’re ready to take action, start with a free water quality test or consult a water filtration expert to learn which system is right for your home.
