Unpacking PFAS, PFOA, and PFOS: What They Are and Why It Matters
The conversation about water quality has grown louder in recent years, and much of the focus has turned to a class of chemicals known as PFAS, including PFOA and PFOS. Often referred to as “forever chemicals,” these substances are incredibly persistent in both the environment and the human body. If you’re concerned about what’s in your water, understanding PFAS and exploring ways to reduce their presence can help you take steps toward improving the water your family relies on every day.
What Are PFAS, PFOA, and PFOS?
- PFAS (Per- and Polyfluoroalkyl Substances): This term covers a large family of man-made chemicals that have been used since the 1940s in products designed to resist water, grease, and stains. Found in everything from non-stick cookware to firefighting foam, their strength lies in their durability—but that also makes them difficult to break down.
- PFOA (Perfluorooctanoic Acid): PFOA has been widely used in manufacturing and is known for its role in heat-resistant applications like non-stick pans. However, its resistance to natural breakdown processes means it can accumulate in the environment, particularly in water supplies, potentially leading to long-term health concerns.
- PFOS (Perfluorooctane Sulfonate): Commonly found in stain-resistant fabrics and certain firefighting foams, PFOS shares many of the same characteristics as PFOA, including its tendency to linger in the environment.
While these chemicals have served specific purposes in manufacturing and consumer goods, their persistence poses challenges when they contaminate water sources.
How PFAS End Up in Your Water
PFAS can enter water supplies through improper disposal, runoff, or leaching from landfills and industrial sites. Communities relying on well water may be particularly vulnerable, as these chemicals can seep into aquifers over time. Once present, they’re difficult to remove without targeted measures.
The Environmental Protection Agency (EPA) recently introduced new regulations to limit certain PFAS in drinking water. However, public water systems have until 2027 to fully comply. This means households may need to take independent action in the meantime to reduce potential exposure.
Health Concerns and Exposure Risks
Research continues to uncover the potential effects of PFAS exposure. Studies suggest links between higher PFAS levels and a variety of health concerns, such as:
- Altered cholesterol levels
- Changes in liver function
- Impacts on immune response and vaccine effectiveness
- Pregnancy-related issues like hypertension
- Associations with certain cancers
While the full picture is still emerging, taking steps to address these contaminants is a practical move for families who want to reduce their risks.
Testing for PFAS in Your Water
The Water Quality Association (WQA) highlights several areas as potential hotspots for PFAS contamination. These include industrial zones where PFAS-containing products are manufactured, landfills, airports, military bases, and farmland treated with biosolids used as fertilizer.
Recent studies point to a widespread presence of PFAS in drinking water across the nation. In fact, PFAS contamination has been detected in numerous locations worldwide. In the U.S. alone, it’s estimated that drinking water for approximately 19 million people in 43 states may contain these chemicals.
The only guaranteed way to determine whether PFAS are present in your water is to have your water tested. The WQA advises that testing be performed by a certified laboratory for the most accurate results. Certified labs can be found through the Environmental Protection Agency (EPA) or your state’s water regulation agency. Keep in mind that laboratory testing can be costly and may take time due to the complexity of sample collection and analysis.
Knowing how widespread the issue is, and the cost of testing for these forever chemicals has many families choosing to invest in a treatment method that addresses PFAS regardless. This proactive action helps them to protect their drinking water supply.
How You Can Address PFAS in Your Home
When it comes to reducing PFAS, not all filtration systems are created equal. A few of the most effective methods include:
- Activated Carbon Filtration: This approach uses carbon to trap PFAS and other substances. It’s often more budget-friendly but works best as part of a larger system.
- Reverse Osmosis (RO): By forcing water through a semipermeable membrane, RO systems significantly reduce PFAS and a wide range of other contaminants.
- Anion Exchange: Using specialized resins, this method captures and holds PFAS from water. It’s often used alongside other technologies for maximum efficiency.
Each solution has its pros and cons, and working with a knowledgeable professional can help you find the right fit for your household’s needs.
