Abstract The purpose of this project is to investigate whether a low-cost multi-stage activated carbon filter system can reduce PFAS-like contaminants from water. By mimicking PFAS properties with negatively charged food colouring and amphiphilic liquid soap, this project demonstrates that activated carbon effectively removes PFAS-like contaminants from water. This project aims to explore practical, accessible methods for safely applying real-world chemical removal processes to improve drinking water quality.
