D'Ambro, E., B. Murphy, H. Pye, C. Allen, K. Talgo, L. Reynolds, K. Brehme, AND R. Gilliam. Exploring air emissions of per- and polyfluoroalkyl substances (PFAS): emission rates, chemical and depositional fate, and transport. 2019 Community Modeling and Analysis System (CMAS) Conference, Chapel Hill, North Carolina, October 21 - 23, 2019.
Impact/Purpose:
This presentation documents the first steps toward modeling the multiscale atmospheric fate and transport of PFAS compounds emitted from stationary sources in the United States. The work evaluates are understanding of current emissions and suggests paths forward for assembling better data with which to assess impacts of PFAS pollutants in the environment.
Description:
We document the development, evaluation and constraint of an analysis tool for better understanding the emissions, chemical transformations and fate of PFAS compounds in the atmosphere. We focus on a case study in outside Fayetteville, North Carolina involving the Chemours Inc. manufacturing and processing facility. We evaluate the model with recent deposition estimates measured directly in the field by the North Carolina Department of Environmental Quality.
