Soil Vapour Intrusion – Evolution of Practices, Current Issues and Future Directions
The course on Soil Vapour Intrusion – Evolution of Practices, Current Issues and Future Directions will cover the latest science, approaches, and methods for effective management of soil vapour intrusion at contaminated sites. Much work and progress has been made in the vapour intrusion practice over several decades including important learnings on conceptual site models […]
GeoPro Talks: Unlocking the Power of Treatability Testing and QA/QC to Remove the Guess Work in Environmental Remediation
Bench-scale treatability testing is an important tool in remedial design. By testing various technologies, amendments and Site-specific variables on a small scale. Using site-specific soil and groundwater samples, this approach helps pinpoint the most efficient treatment strategies— potentially reducing costs and minimizing risks in full-scale implementation. However, bench-scale testing is only part of the equation—quality […]
GeoPro Talks: Controls of Mercury Concentrations in Fish
An overview of factors and processes known to influence concentrations of mercury in fish, with a focus on lake ecosystems in northern regions.
GeoPro Talks: Monitored Natural Attenuation – A Case Study
Come join us this Wednesday February 26 for a classic talk and discussion on Monitored Natural Attenuation – A Case Study. GeoEnviroPro’s Guy Patrick walks us through the common approaches used to assess MNA, and applies these concepts to a major historical petroleum hydrocarbon contaminated site in northern Canada. This Talk was originally recorded in […]
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: Analysis of tire anti-oxidant 6PPD and 6PPD-quinone by LC-MS/MS
For years, scientists struggled to understand the mysterious deaths of coho salmon in urban streams of the US Pacific Northwest, particularly after heavy rainfall. These deaths, known as “Urban Runoff Mortality Syndrome” (URMS), caused up to 90% of coho salmon to die before spawning. Finally, in December 2020, researchers at the University of Washington identified […]
GeoPro Talks: Adopting Digital Tools for Sustainable Remediation
Contaminated sites present unique challenges that require tailored approaches to investigation and remediation. Conceptual site models are conventionally based on snapshots of site conditions, but understanding how contaminant distributions evolve in the subsurface can provide deeper insights. Digital tools based on fundamental physical transport and biodegradation reactions can enhance these models and support decision-making. This […]
GeoPro Talks: City of Vancouver’s Healthy Waters Plan
Based on the principles of “One Water,” the City of Vancouver began the development of a comprehensive long-range plan for sewage and rainwater management in 2020. This initiative, now referred to as the “Healthy Waters Plan”, is an integrated planning effort to address pollution from sewer overflows and urban runoff, adapt to the impacts of […]
GeoPro Talks: Incorporating In Vitro Bioaccessibility for Arsenic and Lead in Soil in Human Health Risk Assessment
The United States Environmental Protection Agency (USEPA) defines bioavailability as the fraction of an ingested dose that crosses the gastrointestinal epithelium and becomes available for distribution to internal target tissues and organs. Bioavailability data can be used to provide realistic information on potential health effects of contamination and modify site-specific soil clean-up levels. Bioavailability is […]
GeoPro Talks: Cost Recovery Claims under BC’s Environmental Management Act – A Legal Update
This presentation, led by environmental lawyers, will provide a legal update on BC’s cost recovery claim under the Environmental Management Act. The session will focus on two key aspects of BC’s cost recovery claim – who can bring such claims and the types of costs that are recoverable. Recent case law will be discussed, as […]
