Geosyntec Staff to Present on PFAS at Michigan's Remediation and Risk Management Webinar Series

Brandon Steets, P.E. (California) and Wayne Amber Ph.D., (Michigan) will present "PFAS in Stormwater: Treatability and Implications of Emerging Water Quality Standards for Dischargers" at Michigan's Remediation and Risk Management Webinar Series from noon to 1 p.m. EDT on July 29, 2021.

Brandon Steets is a Senior Principal Engineer based in California with more than 20 years of experience in National Pollutant Discharge Elimination System (NPDES) and Total Maximum Daily Load (TMDL) regulations, water quality modeling and monitoring, pollutant source investigation, and stormwater best management practices (BMP) planning and design.

Wayne Amber is a Principal Engineer based in Michigan with more than 15 years of experience focused on the development and implementation of site characterization and in situ remediation technologies.

Presentation Description

The presentation will provide an update on the state-of-the-practice for per- and polyfluoroalkyl substances (PFAS) in urban and industrial stormwater, including its abundances, its treatability and implications for source control, and implications for industrial and municipal stormwater dischargers. A summary of available Interstate Technology and Regulatory Council PFAS guidance will be provided with a focus on the state of the science/practice, a summary of what we know (occurrence, fate, transport and toxicology of some PFAS), what we want to know (the same for more PFAS, performance of conventional natural/passive stormwater treatment best management practices (BMP), potential for new treatment methods), and what we don't know (assessment of alternatives to PFAS, the long-term community and ecosystem effects, or the effectiveness of source controls at industrial facilities). A State of Michigan perspective will also be provided, detailing how the Michigan PFAS Action Response Team is leading initiatives to help manage risks from PFAS in stormwater. The presentation will also address lessons learned from Geosyntec's recent PFAS projects as well as the treatability of different PFAS based on their water partition coefficient and percent dissolved as measured during recent field sampling events. An overview of treatment considerations unique to PFAS in stormwater and a range of potential capital and operations and management costs will also be presented.

The Michigan Department of Environment, Great Lakes, and Energy (EGLE), in partnership with the American Institute of Professional Geologists (AIPG), and the Michigan Association of Environmental Professionals, are launching the new Remediation and Risk Management Series. This webinar series is dedicated to helping environmental professionals stay informed about issues and trends that affect remediation and risk management efforts. Each month, EGLE will host a one-hour webinar that will tackle a topic of interest to environmental professionals and others interested in environmental remediation and risk management. Each webinar will include a presentation by a diverse selection of environmental professionals and allow time for questions from attendees.
