This Project Grant from the US Geological Survey, under the Assistance to State Water Resources Research Institutes program (CFDA 15.805), provides $469,361 to The Ohio State University Office of Sponsored Programs from January 2023 to January 2026. The funding will support field observations and numerical simulations to enhance understanding of per- and polyfluoroalkyl substances (PFAS) deposition impacts on hydrologic systems in Ohio. Researchers will deploy air and plant samplers near potential PFAS emission sources to characterize spatial distribution downwind. Soil samples will assess deposition rates. Untargeted and targeted chemical analyses will identify and quantify PFAS mass loading in air, flora, and soil. Researchers will update the Community Multiscale Air Quality model for PFAS to improve atmospheric chemistry representation and evaluate model outputs against field data. Outcomes include a refined national-scale deposition prediction tool to elucidate PFAS air emission impacts on drinking water resources.
