The GPro talk series is a weekly webinar allowing attendees to learn about specific topics related to environmental sciences. Each talk is lead by our senior specialists who’ve spent years in the field gathering experience and knowledge.
Make sure you sign up for the webinars, even if you can’t attend the live sessions, the replays are online for 48 hours post webinar!
GeoEnviroPro Talks will be held every Wednesday at 10 am PST. The topics will be announced a week in advance. We have combined experience with every aspect of practice – from the excavator to the courtroom – and have been involved throughout the evolution of the contaminated field science and regulations in BC. Now distilled freely into 30 minute chunks. These sessions are FREE!
After 35+ years of site investigations and cleanup, we’ve seen a few things out there…and it’s time to share!!
RemChlor-MD process to be an efficient tool to support delineation of old PCE plumes particularly in vertical dimension. RemChlor-MD allows for efficient modeling of layered and heterogeneous systems, and rock systems with parallel fractures and matrix diffusion in aquitards. In this webinar, a short introduction to RemChlor-MD is presented along with a case study where an old PCE plume is simulated.
Caro Analytical services in collaboration with the University of Alberta have developed an analysis that focuses on the cumulative effect of a water source on aquatic life regardless of the complexity of the contaminating mixture. Monitoring an immune response through gene expression allows one to identify stress on a species well before exposure becomes fatal or leads to irreversible effects. The results outlined in this presentation have potential to provide cost-effective methodology for routine and continued monitoring of sites pre-, during, and post-remediation. Bioanalytical end-points will play a large role in our industry moving forward as current analytical methods struggle to stay relevant with a continuously growing list of contaminants of concern. The potential for this technology from both a regulatory and risk-assessment side is immense allowing for simple base lining of an environment while removing uncertainty in scope and ultimately replacing post-contamination sampling programs. This presentation will detail the successes to date and real world applications for this new line of testing with a focus on benefits for stakeholders.

Lidar (light detection and ranging) is a laser-based remote sensing technology. From airborne or ground based platforms, it can be used to collect information about features on the surface of the Earth or in the atmosphere. These data can be used to create three dimensional representations and provide precise location. This presentation will go over how Lidar works, and real-world research applications being conducted by the Selkirk Geospatial Research Centre (SGRC)

Effective stakeholder engagement and consultation is a key component of successful projects, enabling you to solicit feedback, develop constructive relationships, and guide future decision making. This webinar presents a case study of a stream-realignment proposal at a residential development, discussing the challenges of managing technical and social components, and highlighting key lessons learned from the Project.
Appreciable levels of toluene are seen routinely in volatile hydrocarbons reports for soils sourced from pristine northern Alberta wetlands. Often the concentrations exceed the Alberta Tier 1 Criteria for that location. Although it is now commonplace for commercial laboratories to assist clients in determining the likely origin of this compound, the process by which this is being done can be somewhat haphazard and inconsistent. Reasons behind this include the steadily increasing scope of knowledge on the topic and the lack of consensus on how best to apply this knowledge in the laboratory on behalf of the client. In recent years simple diagnostic ratios, or the presence/absence of specific marker compounds, have been used increasingly to formulate a conclusion. Bureau Veritas Laboratories has evaluated these approaches and noted that along with their merits, there are also limitations for a small proportion of cases, which could potentially result in an incorrect interpretation. For these cases it is important to use all the tools in the toolbox prior to drawing any conclusions. The risk of undertaking a needless and costly remediation project is simply too great to not consider all available evidence prior to issuing an interpretative statement on a test report. Likewise, the environmental risks of an incorrect conclusion could be just as costly.
