GeoPro Talks: Best Practices for Investigating PFOS-Alternative AFF
This presentation explores the development of aqueous film-forming foam (AFFF) containing per- and polyfluoroalkyl substances (PFAS), focusing on the rise of next-generation C6 foams introduced in the 2000s. Promoted as environmentally friendlier alternatives to PFOS-based AFFFs, these formulations primarily feature 6:2 fluorotelomer betaine (6:2 FTAB)—a PFAS compound that remains unregulated and lacks an approved analytical […]
GeoPro Talks: PFAS Visualization for Site Characterization and In-Situ Remediation Assessment
Several case studies at U.S. military sites are presented to demonstrate the benefits of PFAS visualization using radial diagram and stacked bar maps for site characterization, in-situ remediation monitoring, and forensic assessments. The use of PFAS ratios and specialized methods for visualizing TOP assay results on a site map are discussed.
GeoPro Talks: Emerging Contaminants
The presentation, recorded at GeoEnviroPro’s Remediation Now Workshop in November, explores our current understanding of the sources, environmental fate and effects, and regulatory status of three emerging contaminants: PFAS, 6PPD-Quinone and Pharmaceuticals/Personal Care Products.
GeoPro Talk: PFAS From a Legal Perspective
Description of current regulatory regime for PFAS and potential future approaches.
GeoPro Talks: CFB Comox Firefighter Training Facility PFAS Novel Source Control (with 3-year update)
SLR’s 2021/2022 award winning CFB Comox project implemented novel in-situ and ex-situ PFAS management methods (amendment and thermal treatment, respectively). To reduce PFAS concentrations in downstream site surface water, the highest concentration materials were targeted for management. This presentation will introduce project design and provide an update on environmental conditions three years after implementation.
GeoPro Talks: PFAS Regulatory Flux – A Legal Perspective
PFAS have been an “emerging contaminant” for some time. As technical knowledge increases in the environmental professional sphere, is Canadian law keeping up? This presentation reviews key considerations about the state of PFAS regulation in Canada and considers questions such as: What is law and what is not law relating to the regulation of PFAS? […]
GeoEnviroPro Talks – Investigating PFAS under the CSR
PFAS in the Environment
GeoPro Talks – Tackling PFAS Today: A Contractor’s Perspective.
Concrete actions are being taken today by custodians to mitigate the growing concerns around Per- and polyfluoroalkyl substances (PFASs) found in the environment. This presentation explores some challenges and solutions.
GeoPro Talks – Lessons from Over 200 Full-Scale PFAS Water Treatment Systems
Case studies will illustrate how challenges re: pretreatment, waste minimization, and precursor formation have been overcome, and why integrating PFAS concentration technologies with destruction technologies can result in zero waste leaving a site.
