January 23 Webinar
Emerging Research on on the Fate, Transport, and Plant Uptake of PFAS in Biosolids

You are invited!

Join Bloom for a webinar featuring leading researchers sharing new findings on the behavior and impacts of PFAS in land-applied biosolids, from soil concentrations to plant uptake. Dr. Ian Pepper, environmental microbiologist and Regents Professor of Environmental Science at the University of Arizona, will present key conclusions from the National Collaborative PFAS Project, a national field study of biosolids land application. His research addresses critical questions around PFAS occurrence, mobility in soils, and movement into associated groundwater at long-term application sites.

Participants will also hear from Dr. Linda Lee, Distinguished Professor of Agronomy at Purdue University, on her groundbreaking research into the fate of PFAS in biosolids-amended agricultural soils, including plant uptake. Chris Peot, Director of Resource Recovery for DC Water, will round out the program with a summary of additional contextual data, including side-by-side comparisons of soil amendments, rainwater deposition, and more. Whether you’re already immersed in the science or newly exploring PFAS as a concerned citizen, this webinar will offer accessible insights and information for everyone.

Featured Speakers

Dr. Linda S. Lee is a Distinguished Professor at Purdue University with a joint appointment between the Colleges of Agriculture and Engineering. She joined Purdue in 1993 with degrees in chemistry (BS), environmental engineering (MS), and soil chemistry/contaminant hydrology (PhD) from the University of Florida. Her research includes chemical fate, analytical tools, waste reuse, bioaccumulation, and contaminant remediation and management strategies with PFAS challenges driving much of her research for the last two decades. Dr. Lee has published almost 200 publications with most in top-tier environmental journals.  

Dr. Ian Pepper is an environmental microbiologist and Regents Professor of Environmental Science at the University of Arizona. His research has focused on the fate and transport of pathogens in air, water, soils and municipal wastes. More recently, he has investigated the potential for real-time detection of contaminants in water distribution systems. Dr. Pepper has co-authored numerous books and journal articles on Environmental Microbiology and Pollution Science, and is a fellow of the American Association for the Advancement of Science, the American Academy of Microbiology, the American Society of Agronomy, and the Soil Science Society of America. He received his PhD in Soil Microbiology from The Ohio State University, MS in Soil Biochemistry from Ohio State, and BS in Chemistry from the University of Birmingham, Great Britain.

Chris Peot is Director of Resource Recovery for DC Water and Interim President of Blue Drop, directing an array of projects for Blue Plains, the world's largest advanced wastewater treatment plant, from the Bloom biosolids program to renewable energy. Before joining DC Water, he was a consulting engineer in Seattle. He began his career in the City of Los Angeles’ Bureau of Sanitation, where he worked on biosolids management and water reclamation. A licensed professional engineer, Chris has a BS in Civil/Environmental Engineering from the University of Wisconsin-Madison and a MS in Civil Engineering from California State University at Long Branch. Chris is also a Water Environment Federation fellow and recipient of the Mid-Atlantic Biosolids Association's 2025 Lifetime Achievement Award.
