How PFAS Moves from AFFF Areas to Groundwater
Wednesday, 29 October, 2025

Join our host Craig Divine and our guest Charles Schaefer. You are listening to The PFAS Research and Remediation Podcast, produced and created by Arcadis with funding from the Environmental Security Technology Certification Program, ESTCP grant number ER-23 7692 through the United States Department of Defense. The Environmental Security Technology Certification Program (ESTCP) is the U.S. Department of Defense’s environmental technology demonstration and validation program. The program’s goal is to identify and assess innovative technologies that address DoD’s high-priority environmental requirements efficiently and cost-effectively. In this second season, we're focused on PFAS and interview a broad panel of experts who have each contributed to the growing knowledge base around remediating this emerging chemical of concern. Today we'll be speaking with Dr. Charles Schaefer, an environmental scientist and director of CDM Smith’s research lab in Bellevue, Washington. His work focuses on understanding and treating PFAS contamination in groundwater and soil. A leading researcher with over 50 scientific publications, he has led major SERDP and ESTCP projects and received multiple Project of the Year awards. Today, we’ll be talking with him about several projects exploring how PFAS move through the unsaturated zone in AFFF source areas and potentially migrate into groundwater.
