PFAS REMOVAL FOR MUNICIPAL DRINKING WATER

Abstract

Poly- and perfluoroalkyl substances (PFAS) are hazardous synthetic chemicals that pose significant health risks and have contaminated water supplies in many communities, including a community in the Southside of Tucson, Summit, Arizona. In response, this project proposes a water treatment solution targeting the region's need for clean and safe drinking water. The REAL Water Treatment Plant combines granulated activated carbon filtration with advanced oxidation to effectively remove PFAS and other contaminant 1,4-dioxane. The treatment process effectively removes PFAS concentrations to levels well below the EPA drinking water regulations. To optimize efficiency, the system includes breakthrough modeling that extends the lifespan of filtration media, reduces waste, and minimizes operational costs. Environmental stewardship is central to the design, with a strong emphasis on reducing chemical waste and carbon emissions through media reactivation rather than landfill disposal. Safety protocols are also in place to manage potentially hazardous materials used in the oxidation process. This project provides a model for how communities can address PFAS contamination while promoting environmental responsibility and economic viability. Its successful implementation can serve as a blueprint for broader efforts to ensure universal access to clean water.
