The persistence and bioaccumulation of perfluorinated chemicals (PFCs) like PFOA and PFOS pose a significant threat to drinking water safety. These compounds, renowned for their stability and water/oil-repellent properties, have been used in numerous industries, leading to widespread environmental contamination.
Key Historical Uses Include:
- Non-stick coatings for cookware
- Waterproofing agents for apparel, carpets, and upholstery
- Food-contact coatings for paper packaging and cartons
- Fire-fighting foam
- Industrial surfactants and mist suppressants
In response to this public health challenge, granular activated carbon (GAC) filtration has been validated by scientific research as an effective method for removing PFOA and PFOS from municipal water.
