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: 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: Ex-Situ Thermal Desorption of Highly- Impacted Mercury Soils in an Urban Area
In-Situ and Ex-Situ Thermal Desorption (ISTD and ESTD) are technologies based on thermal conduction that can effectively treat organic contaminants, independently of large soil heterogeneity. One of its applications is for contaminated properties in urban areas and under existing buildings. The main principle of the technology resides in installing a network of steel pipes acting […]
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.
