Analyzing the Feasibility of a Centralized Treatment System for the Implementation of Destructive PFAS Treatment Technology

Abstract

Per- and polyfluoroalkyl substances (PFAS), are emerging contaminants that pose a significant threat to water systems across the U.S. PFAS compounds are difficult to break down and long-term exposure to them can have adverse health effects. 374Water is a technology company that has developed a destructive solution for organic wastes including PFAS through a process called supercritical oxidation. This study examined the financial feasibility of implementing their technology in a centralized wastewater treatment system. It assessed whether the centralized model is viable for 374Water and for individual utilities in North Carolina and Maine. Study results showed a positive business case for Maine. In North Carolina, where there is limited PFAS policy, project implementation was not feasible. 374Water AirSCWO™ implementation should be focused on states with strict PFAS disposal regulations that drive up biosolid disposal costs.
