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: 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: 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: 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 […]
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 Talks: Remediation of Chemetron Lagoon: Overcoming Challenges in Hazardous Waste Management
The Chemetron Lagoon (CL) project focused on the remediation of a former industrial site contaminated with hazardous materials, including polychlorinated biphenyls (PCBs). The project successfully excavated and solidified PCB-contaminated sludge, and upon completion, the site will be transformed into parkland, offering social and economic benefits to the residents of Port Hope.
GeoPro Talks: Identification of New Preferential Pathways for Vapor Intrusion of Chlorinated Solvents Found by combining VaporSafeTM and Detection Dogs
The site was one of Stockholm’s largest dry cleaners and vapor intrusion of Chlorinated Aliphatic Hydrocarbons (CAH) to the adjacent apartment buildings had been identified as the primary risk driver. The results of standard investigations were however puzzling regarding how vapor entered into these buildings. To identify the cause of the elevated concentrations of CAH […]
GeoPro Talks: The Power and Benefits of Using Hydrogeological Conceptual Site Models at Contaminated Sites
Hydrogeological conceptual site models (CSMs) adapted to the environmental field are often not used or are underutilized when completing contaminated site investigation and remediation work. CSMs can be an effective tool even in the earliest stages of a contaminated sites investigation when no intrusive geologic, hydrogeologic, or chemistry data has been collected. If used at […]
