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!!
Overview of Climate Change Impacts on Site Remediation & Sustainable Management of Petroleum Hydrocarbon Siteskeyboard_arrow_downDecisions made around technology selection for management of sites, when considered on a larger scale and number of sites, can impact the changing climate, most notably through the carbon footprint of activities for the investigation and remediation of these sites. In turn, the changing climate is impacting the design and management of contaminated sites. Key factors in climate projections such as sea level rise, flooding, precipitation, wildfires and land erosion have been identified in various guidance on climate adaptation for contaminated sites management.Vulnerability assessment of sites to these factors can be incorporated in the development of the conceptual site model for the design and performance monitoring of the remediation system.We consider sustainability measures for remediation of petroleum hydrocarbon (PHC) sites,which represent a large number of contaminated sites ranging from small gas stations to refineries with multiple LNAPL source zones. Multi-site database studies comprising of data from thousands of sites have identified unique aspects of PHC sites on groundwater plume lengths and stability on an empirical basis that demonstrate the significant role of biodegradation on the natural attenuation of PHCs. On a site-specific basis, however, tools and methods are required to quantify the rates and remediation time frames that can be used for informed decision making on site management.

Join Scott Steer on November 6 for an introduction to the application of risk assessment as a tool in the sustainable remediation of contaminated sites. Seven key risk assessment concepts will be discussed in addition to regulatory context and some history.
Environmental remediation has been less privileged when it comes to the use of nano-technologies compared to electronics, aviation and pharmaceutical industries. Graphene; a single layer of carbon atoms, is truly the wonder material of the 21st century and has the potential for revolutionizing the environmental sector. Its vast surface area provides tremendous adsorption capacity for metals and a variety of organic contaminants. It can be functionalized, magnetized and form the basis for nano-composites to target certain contaminants in aqueous and gaseous phases. This presentation provides an introduction to Graphene based nano-materials and their application in environmental remediation.

Environmental DNA (eDNA) technology is poised to revolutionize the way ecological and environmental assessments are conducted, enabling higher rates of detection for rare species without the need for directly observing or capturing the study organism. eDNA refers to the genetic material released by an organism to its environment as dead cells, scales, hair, feces, body fluids, gametes, etc. This material can be collected from the environment through water sampling and tested to determine recent presence of the target species. This webinar will provide an introduction to eDNA technology, review field and laboratory methods and describe applications through case studies involving environmental assessments conducted for residential/commercial development projects, mining and conservation biology.

Sustainable Remediation Policy – Where have we come from? Where should we be heading?keyboard_arrow_downThis week we will be presenting a recording of a talk given by Guy Patrick and Reidar Zapf-Gilje at our 'Risk Solutions for Contaminated Sites - Sustainable Remediation' workshop this past May.The presentation explores sustainable remediation principles, the importance of alignment between these principles and regulatory policy, and how risk assessment fits in.
Perspectives on Emerging Contaminants: Technology Advances and Field Applications in Remediation of Emerging Contaminantskeyboard_arrow_down
Emerging contaminants are a challenge for contaminated sites as they add uncertainty and cost to strategies for characterization and remediation. Advancing these strategies requires a substantial investment in research and development, as the chemical properties of emerging contaminants are often not well understood. In the early 2000s, multiple emerging contaminants were identified, including MTBE and oxygenates, 1,4-dioxane, NDMA, perchlorate, select pharmaceuticals, PFOS and others. Roll forward to 2019 and we can see that systematic and effective approaches to address some of these contaminants (i.e., MTBE) have been developed, while some contaminants continue to pose challenges (perchlorate, 1,4-dioxane) all while other emerging contaminants continue to be identified. Emerging contaminants such as TBA, 1,4-dioxane, perchlorate, pharmaceuticals, perfluorylalkyl substances (PFAS), selenium, microplastics and sulfolane are an on-going concern at many sites. With the development of new chemicals for various commercial, pharmaceutical, industrial and military purposes, we can expect that we will continue to face new emerging contaminants in the future. This presentation will discuss the history of emerging contaminants of concern at contaminated sites. It will then provide a focused discussion on several current emerging contaminants, including PFAS, 1,4-dioxane, selenium and sulfolane. This will include the use history and key characteristics that challenge remediation practitioners in developing investigation and remedial strategies. Finally, recent advances in remediation tools for these compounds will be discussed including both ex situ and in situ options. Case study results for promising technologies that can provide treatment of each of these constituents will be provided.
