Webinar Series on PFAS – Assessment, Treatment Options and Lessons Learned
REGENESIS has been working with several consultancies, problem holders and universities around the world on the challenges that PFAS poses in the environment. Together, we have completed a number of successful laboratory, pilot and full-scale applications.
Webinar Recordings on Demand
In our PFAS webinar series, guest speakers explain more about these challenging contaminants, including lessons learned during site investigation, in situ remediation and modelling tools for treatment evaluation.

PFAS Contamination in Minnesota, US: Lessons Learned, Fate and Transport, and Reducing Exposure
In this webinar Virginia (Ginny) Yingling, Senior Hydrogeologist in the Environmental Health Division of the Minnesota Department of Health, discusses: The State of Minnesota’s investigation of an area of PFAS-contaminated groundwater that covers over 150 sq. miles; Challenges faced by Minnesota Department of Health in communicating the risk of PFAS to the public; Lessons learned from the state’s investigation of a chemical production facility; Key aspects of unique PFAS fate & transport behaviour observed, and successes in reducing exposures. Ginny is joined by Kristen Thoreson, PhD, Director of Research and Development at REGENESIS.
Challenges of PFAS in Groundwater – Lessons learned for Michigan’s Survey of Community Water
Guest presenters Steve Silver of the Michigan Dept. of Environmental Quality, and Patricia Byrnes Lyman, of the Michigan Dept of Military and Veterans Affairs (US), discuss the challenges of PFAS in groundwater and lessons learned from Michigan’s survey of community water: Discovery of unacceptable levels of emerging contaminants like per- and polyfluoroalkyl substances (PFAS) in a community water supply; Immediate and longer-term actions to protect public health and ensure a reliable supply of safe drinking water; Lessons learned during Michigan’s survey of all its community water supplies in 2018.
Successful In Situ Remediation of PFAS in Canada
Remediation Expert Rick McGregor, President of InSitu Remediation Services Ltd in Canada, presents a PFAS remediation case study of a former industrial furniture manufacturing site in Canada on which a fire training facility was co-located. The site was to be remediated for petroleum hydrocarbon contamination when analysis indicated that PFOA and PFOS was present within the groundwater. Using direct push technology, Liquid Activated Carbon along with ORC Advanced was injected at 50 locations within the silty sand aquifer to address the groundwater contamination. Ongoing validation testing (now over 34 months) has shown that the PFOA and PFOS, as well as the petroleum hydrocarbons, had been rapidly reduced and maintained at below detection limits.
Eliminating Risk of PFAS Contamination – Low Cost In-Situ Remediation with Colloidal Activated Carbon
In this technical webinar, Scott Wilson, President & CEO of REGENESIS discusses eliminating risk of PFAS contamination in soil and groundwater via low-cost in-situ remediation with colloidal activated carbon. By coating flux zones of an aquifer with colloidal activated carbon, a permeable sorption barrier is created in-situ, purifying groundwater as it passively migrates. PFAS constituents from up-gradient source zones are rapidly sorbed to the carbon and removed from the mobile dissolved phase. By removing PFAS from the mobile phase, the route of exposure to down-gradient receptors is eliminated, thereby eliminating the down-gradient public health risk associated with PFAS.
In Situ Remediation: Modeling and Visualization Tools (including PFAS case study)
In the webinar, guest speaker Grant Carey, PhD, President of Porewater Solutions and Adjunct Professor in the Department of Civil Engineering at the University of Toronto discusses Visual Bio™ and ISR-MT3DMS™, two visualization and modelling tools for evaluating remediation performance. As part of this, he discusses how to reliably predict the treatment longevity of a PFAS impacted site in Canada where PlumeStop was applied in barrier formation.
