Webinar Summary
This webinar will address the formidable challenges of PFAS contamination in groundwater and other impacted media. The session will begin with an overview of the problem and a review of PFAS chemistry, emphasizing their persistent nature and resistance to degradation compared to other contaminants. It will then examine conceptual models that elucidate the fate and transport of PFAS in the subsurface, with particular focus on matrix diffusion and sorption processes. Attendees will gain insights into ex situ pump‐and‐treat systems along with various PFAS treatment alternatives (including destruction), as well as emerging in situ treatment strategies—including permeable sorption barriers—that offer rapid risk reduction. The webinar will conclude by summarizing current research trends that have led to the development of PFAS Monitored Retention and PFAS Enhanced Retention strategies for the remediation community.
Webinar Format
This webinar will include a moderated Q and A session following the speaker’s presentation. The session is open to environmental engineering and science professionals across all sectors and career stages. Our objective is to offer special insights on leading edge solutions for graduate and undergraduate students as well as early to mid-career environmental professionals who are considering specialty certification.
