The Cape Fear River basin is the largest watershed in North Carolina, and it provides drinking water for about 1.5 million North Carolinians. In this presentation, I will highlight advances in analytical methods to characterize sources of per- and polyfluoroalkyl substances (PFAS) and their effects on surface water quality in the Cape Fear River basin. In addition, I will describe how stakeholder engagement has led to source control efforts and engineered interventions that have dramatically reduced human exposure to PFAS in communities that receive drinking water from public water systems that treat surface water. Finally, I will present effects of air emission from a fluorochemical manufacturer on private well communities.
