Title: The Challenges of Treating PFAS - The Forever Chemicals
Per- and polyfluoroalkyl substances (PFAS), also known as the “forever chemicals” are a stable, synthetic class of chemicals that have contaminated air, soil, biota, surface water, and groundwater. Because concentrations in the environment are much greater than regulatory guidelines allow, cost effective treatment approaches are needed that consider the unique chemical properties of PFAS – they are highly soluble, thus move into and readily within water systems, and most PFAS compounds do not break down under normal environmental conditions.
This presentation will introduce approaches for removing PFAS from water and recent related research activity. Technologies of particular focus include sonolysis and plasma treatment. The presentation will also highlight recent research to advance and optimize PFAS treatment technologies, with a particular emphasis on treatment trains for more efficient and effective remediation. Some of the socioeconomic challenges of addressing PFAS contamination will also be introduced.
About the Speaker: Michelle Crimi, Clarkson University
Michelle Crimi is a Professor jointly appointed in Civil & Environmental Engineering and Engineering & Management at Clarkson University. Her research focuses on developing in situ treatment technologies for groundwater contamination, determining the impact of groundwater technologies on aquifer quality, and integrating treatment technologies for optimized risk reduction. Her projects are often conducted in partnerships with industry and consulting organizations and have a strong technology transfer focus with the objective of moving technologies from the laboratory to full scale adoption by developing guidance, tools, protocols, and workshops to support field application. She has been PI or co-PI on several research projects focused on treating emerging contaminants, funded primarily by the U.S. Department of Defense’s Strategic Environmental Research and Development Program (SERDP) and the Environmental Security Technology Certification Program (ESTCP). She earned her B.S. in Industrial Hygiene and Environmental Toxicology from Clarkson University, her M.S. in Environmental Health from Colorado State University, and her Ph.D. in Environmental Science and Engineering from the Colorado School of Mines. She spent the 2014-2015 academic year as a Fulbright Scholar at the University of KwaZulu-Natal in Durban, South Africa.
