PFAS and PFOA, also known as forever chemicals, are man-made substances that resist natural degradation. They are commonly found in various industries and everyday items. Exposure to these chemicals has been linked to health issues, leading to increased regulations. Testing methods, government regulations, and best practices are discussed to avoid and remove harmful PFAS and PFOAs from water. Understanding their sources and effects and taking preventive measures can help minimize exposure and protect health.

PFAS and PFOA: The Forever Chemicals

PFAS (Per- and Polyfluoroalkyl Substances) and PFOA (Perfluorooctanoic Acid) are commonly known as "forever chemicals" due to their resistance to breaking down naturally in the environment.

These harmful PFAS chemicals have been widely used in various industries, including manufacturing, firefighting, and food packaging. However, their persistence and potential health risks have raised concerns. This pillar page aims to provide comprehensive information on toxic PFAS and PFOAs, including their sources, effects, government regulations, testing methods, and best practices to avoid and how to remove them from water.

Toxicity studies on PFAS (Per- and Polyfluoroalkyl Substances) and PFOAs (Perfluorooctanoic Acid) in water and other items have revealed concerning results. These studies have highlighted the potential health risks associated with these chemicals. Exposure to PFAS and PFOAs has been linked to various adverse effects, including liver damage, developmental problems, immune system disorders, and certain cancers. The persistence of these chemicals in the environment and their ability to accumulate in living organisms raise significant concerns. Ongoing research and toxicity studies are crucial in understanding the risks and developing strategies to mitigate exposure and protect public health.

Understanding PFA's and PFOAs



  • PFAS and PFOA can be found in water sources, such as lakes and rivers, as well as in everyday items like non-stick cookware, waterproof fabrics, food packaging, and firefighting foams.

Health Effects:

  • Studies have linked exposure to PFAS and PFOA to various health issues, including liver damage, developmental problems, immune system disorders, and certain cancers.
  • The potential health risks have led to increased scrutiny and efforts to regulate and limit the use of these chemicals.

Government Regulations

United States:

  • Environmental Protection Agency (EPA): The EPA has issued health advisory levels for PFAS and PFOA in drinking water and has taken steps to regulate and monitor these chemicals.
  • Safe Drinking Water Act: The act empowers the EPA to establish maximum contaminant levels for substances in drinking water, including PFAS and PFOA.

International Regulations:

  • European Chemicals Agency (ECHA): The ECHA has restricted the manufacturing, use, and marketing of certain PFAS and PFOAs under the REACH regulation.
  • Stockholm Convention: PFOA has been added to the list of Persistent Organic Pollutants (POPs) under this global treaty, aiming to eliminate or restrict the production and use of these chemicals.

Testing for PFAs and PFOAs

Water Testing:

  • Home Test Kits: Various commercially available water test kits can detect the presence of PFAS and PFOA in drinking water.
  • Certified Laboratories: Professional testing labs can accurately and comprehensively analyze water samples for PFAS and PFOA.

Avoiding exposure to PFAS:

  • Minimize using products containing PFAS and PFOA, such as non-stick cookware and stain-resistant fabrics.
  • Choose alternative products labeled as PFA-free or PFOA-free.
  • Avoid microwaving food in plastic containers, as they may contain these chemicals.

How To Remove PFAS From Water:

Water Filtration:

  • Granulated Activated Carbon (GAC) Filters: GAC filters can effectively remove PFAs and PFOAs from water, but checking the filter's specifications is important.
  • Reverse Osmosis (RO) Systems: RO systems can efficiently remove a wide range of contaminants, including PFAs and PFOAs.

Best Practices:

  • Stay informed about product labels and research regarding PFAS and PFOAs.
  • Support organizations and initiatives advocating for stricter regulations and safer alternatives.
  • Follow local guidelines for disposing of products containing PFAS and PFOAs.
