Topic: Poly- and Perfluoroalkyl Substances: Current State of Knowledge

Speaker: Dr. Christopher Higgins, PhD Associate Professor, Department of Civil and Environmental Engineering, Colorado School of Mines

Date/Time: Tuesday, August 14, 11:30am-1pm

 CEMS will not be applying for a CLE for this presentation

Growing concerns about human exposure to perfluorooctanoate (PFOA) and perfluorooctane sulfonate (PFOS), two members of the broad family of poly- and perfluoroalkyl substances (PFASs), have led to significant interest in characterization and treatment of sites contaminated with PFASs, particularly those derived from aqueous film-forming foams (AFFFs).  Many challenges exist related to PFASs due to their unique properties and their resultant fate and transport behavior.  Significant challenges are also evident for developing treatment and remediation technologies, mainly due to both the recalcitrance of the perfluoroalkyl acids (PFAAs) and the complexity of their polyfluorinated chemical precursors. Advances in analytical techniques, particularly in characterizing the levels and identities of polyfluorinated chemical precursors, have given rise to opportunities to address these challenges even in the absence of definitive information for an impacted site. In this overview, these challenges will be discussed in the context of characterizing PFAS-impacted sites, evaluating potential for human exposure to PFASs, and existing treatment technologies for water and soil treatment. Further, their implications with respect to ongoing remediation and treatment research will be presented.

He joined faculty at the CSM in 2009, and was promoted to Associate Professor in 2014.  His research focuses on the movement of contaminants in the environment. In particular, he studies chemical fate and transport in natural and engineered systems as well as bioaccumulation in plants and animals, with a focus on poly- and perfluoroalkyl substances. Dr. Higgins has authored more than 65 peer-reviewed publications to date, and he has been an invited speaker at many national and international conferences. His research has been supported by the National Science Foundation, the National Institutes of Health, the U.S. Environmental Protection Agency, the U.S. Department of Agriculture, the U.S. Air Force, and the U.S. Department of Defense’s Strategic Environmental Research and Development Program (SERDP) and Environmental Security Technology Certification Program (ESTCP).
