GeoPro Talks: Environmental Remedial Injections Techniques
This presentation will focus on the appropriate use of in-situ injections as a remedial tool for contaminated sites. It will introduce the two types of injection behaviour — permeation and fracture injection — and address the direct injection myth. The importance of injection flow rate in controlling injection mode, and how to use pressure and […]
GeoPro Talks: Controlled Methane Injection Pilot Demonstration of a Biocover Concept for Mitigating GHG Emissions from Integrity Compromised Oil and Gas Wells
Well integrity failure is an expensive historic and ongoing issue associated with a subset of oil and gas wells. Failure manifests as surface casing vent flow (SCVF; inside casing leakage) and/or gas migration (GM; outside casing leakage) whereby natural gas (comprised primarily of methane) is potentially emitted to atmosphere causing greenhouse gas (GHG) emissions. Remediation […]
GeoPro Talks: Optimizing Remediation Portfolios using Decision Science and Project Management
Dan and Tim will introduce decision science tools and frameworks and use case studies to illustrate how adoption of decision science tools combined with project management processes can be employed to optimize remediation portfolios. Case studies will illustrate how teams can shape projects and portfolios that achieve multiple owner, regulator, stakeholder and rights holder objectives, […]
GeoPro Talks: Latest Advancements in Data Integration and Automation in Environmental Science with Live Demos
In today’s data-driven world, decision-makers in environmental monitoring need seamless solutions that transform raw data from multiple sources into actionable insights. This presentation introduces a custom, open-source platform designed to automate the entire data pipeline—from ingestion and integration to analysis and decision-making. By unifying data from various sources, such as field sensors, GIS, and historical […]
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 […]
