Hidden Dangers in Your Tap Water: How to Remove PFOA and PFOS
Is your drinking water secretly harming your family?Invisible "forever chemicals" like PFOA and PFOS linger in water sources nationwide, from city taps to private wells. Here's how you can protect your health by effectively removing these contaminants.
Why Are PFOA and PFOS in Our Water? TPFOA (Perfluorooctanoic Acid) and PFOS (Perfluorooctane Sulfonate) are man-made chemicals known as PFAS. Commonly found in non-stick cookware, firefighting foams, waterproof clothing, and food packaging, they resist breakdown and persist in the environment, eventually contaminating water supplies.
Health Risks of PFOA and PFOS
Exposure to these chemicals can lead to significant health issues:
-
• Certain cancers (kidney and testicular)
-
• High cholesterol and liver damage
-
• Weakened immune systems
-
• Hormonal and developmental problems, especially in infants and children
The EPA recommends limiting these chemicals to just 4 parts per trillion (ppt) in drinking water, underscoring their serious health risks.

How to Remove PFOA and PFOS Effectively
You can effectively treat your water for PFOA and PFOS using the following methods:
Activated Carbon Filters
Activated carbon systems:
- Use specially treated carbon material to absorb contaminants
- Trap chemicals like PFOA and PFOS due to their porous structure
- Available as whole-house systems (main water line) or under-sink units
- Ideal for comprehensive home or business filtration
- Require regular replacement every 6-12 months for continued effectiveness
Reverse Osmosis (RO) Systems
Reverse osmosis systems:
- Filter water through a fine, semi-permeable membrane
- Remove PFOA, PFOS, heavy metals, and many other dissolved contaminants
- Typically installed under kitchen sinks for targeted filtration
- Provide high-quality filtered drinking water directly from the tap
- Need regular maintenance, including periodic pre-filter and membrane replacements (usually annually)
- Ion exchange resins are synthetic, polymer-based beads specifically designed to remove contaminants from water.
- These resins attract harmful ions such as PFOA and PFOS, exchanging them for harmless ions like sodium or chloride.
- Provide highly effective, robust, and high-capacity removal of contaminants.
- Particularly suited for large-scale commercial and industrial water treatment applications.
- Require periodic regeneration or replacement of resins to maintain peak effectiveness.
Always select filtration systems specifically certified to handle PFOA and PFOS.
Here’s how to pick the best filtration solution for your situation:
- Activated carbon: Ideal for treating all water entering your home or business.
- Reverse osmosis: Best suited for targeted drinking water filtration at specific taps.
- Ion exchange: Recommended for severe contamination or commercial applications.
Always select filtration systems specifically certified to handle PFOA and PFOS.
- "Forever chemicals" like PFOA and PFOS pose serious health risks.
- Standard methods (like boiling) won't remove these contaminants.
- Activated carbon and reverse osmosis systems are highly effective treatment options.
Frequently Asked Questions (FAQs)
Q: Does boiling water remove PFOA and PFOS?
HNo, boiling water does not remove these chemicals. It can actually concentrate them.
Q: Do fridge or pitcher filters remove PFOA and PFOS?
Most fridge and pitcher filters are not certified to remove these contaminants reliably. Certified activated carbon or reverse osmosis systems are necessary.
Q: Should private well water be tested for PFOA/PFOS?
Yes, regular testing is crucial to identify and manage these chemicals in private well water.
