Poly- and perfluoroalkyl substances (PFAS), also called “forever chemicals,” are a serious problem in water across the United States. These toxic chemicals do not break down naturally, build up in people and animals, and are linked to major health risks. Current water treatment methods cannot destroy PFAS because of their very strong carbon-fluorine bonds. This project will develop and test a new method called Continuous-flow Liquid-phase Plasma Discharge (CLPD). The CLPD system creates powerful chemical reactions in water to break apart PFAS completely, without making new harmful byproducts. If successful, this could be a simple, chemical-free, and low-energy way to clean PFAS from water. The project integrates educational outreach and workforce development components, including new course offerings, research opportunities for high school, undergraduate, and graduate students, and dissemination to stakeholders through professional development resources. This project aims to engineer and investigate a Continuous-flow Liquid-phase Plasma Discharge (CLPD) process designed for the complete defluorination and mineralization of poly- and perfluoroalkyl substances (PFAS) in water. PFAS represent a persistent class of contaminants due to their strong carbon-fluorine (C-F) bonds, which resist conventional chemical and biological degradation, leading to bioaccumulation and significant health concerns. While nonthermal plasma discharge shows promise for degrading recalcitrant poll
