Abstract: Per- and polyfluorinated alkyl substances (PFAS) represent a public health risk when they enter water bodies. Our project seeks to investigate the role that air emissions of PFAS, and their subsequent deposition back to the surface, have on the environment near these sources within the state of Ohio. We will collect samples in air, pine needles, and soils to determine which, and how much, PFAS are present in the environment near these sources. We will use a computer model to predict the atmospheric transport and surface deposition of PFAS. We will use our environmental samples to evaluate the accuracy of the model predictions, and we will update the model’s chemistry, as needed. Ultimately, this model can be used to predict PFAS deposition across the US, providing a better understanding of the role that air emissions of PFAS have on drinking water contamination on a national scale.
