GPro Talks

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!

Past talks are available to purchase individually or through all access memberships.

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!!

    Managing Complex Sites with Deep Multilevel Characterizationkeyboard_arrow_down

    How do repeatedly measure water levels and obtain water samples from monitoring wells completed in an aquifer beneath thick permafrost?  How do you stop the water in the well from freezing?  And how do you characterize an aquifer that’s been cross-contaminated by a deep open borehole?  Join us on Wednesday April 8 at 10 AM Pacific, when John Sankey of True Blue Technologies presents more fascinating case studies where novel applications of multilevel monitoring systems were used to develop an effective conceptual site model.

    Stakeholder Roadmap: A Guide to Effective Active Engagement using Social Methodologieskeyboard_arrow_down

    Stakeholder engagement is thought to be elusive, complex, and expensive. Currently, remediation industry has acknowledged to be deficient in this area, in 2015 an international SuRF project published how to better integrate the social dimension. This presentation builds on that work. Active stakeholder engagement is beneficial to projects by reducing delays. And, using known, effective engagement strategies allows for better outcomes for consultants, proponents, and the community. As there is no ‘one-size-fits-all’ approach that is appropriate for any project, this roadmap sets out to demystify engagement, and uses guiding principles in a framework allowing users help effectively guide their stakeholder engagement process.

    In-Situ Biological Treatment of Metals Impacted Groundwaterkeyboard_arrow_down

    Groundwater impacts at mining sites are often comingled mixtures of sulfate, associated with the sulfuric acid leach solutions commonly used in mineral extraction, as well as various metals associated with the ore body or host rock being mined.  The focus of the research presentation is the development of cost effective and reliable processes for biologically reducing sulfate, yielding biological and abiotic chemical processes that result in the precipitation or geological sequestration of the metal-based contaminants present in the groundwater at mining sites. This presentation describes the development and microcosm testing of SiREM’s MB-1® sulfate reduction consortium, grown in water from a metal impacted mine site located in Chile.  This research is ongoing and is the basis of new in-situ passive approaches and bioremediation products for remediating metal-based groundwater contamination at mining sites.

    Managing Complex Sites with High Resolution Site Characterization and Focused Remediationkeyboard_arrow_down

    Recent groundwater characterization and instrumentation approaches have proven helpful in providing a sound and defensible Conceptual Site Model (CSM) to help design a range of different remedies to reach the overall goal at a complex site. High Resolution Site Characterization. An integrated approach has been developed to use ultra-high resolution scanning technology and three-dimensional (3-D) data integration and visualization, to more effectively characterize baseline groundwater hydrogeology, contaminant distribution, and identify microbially active subsurface zones as confirmed by Next Generation Sequencing. Focused Remediation. – At the South Tacoma Channel Superfund site in Tacoma, Washington, targeted remedies were applied within the complex stratified regime.

    Phytoremediation Technologies for Conserving Salt and Hydrocarbon Contaminated Soilkeyboard_arrow_down

    All too often the solution of choice for dealing with contaminated soil is to dig it up and dump it in a landfill. It’s an easy solution in Canada where space is plentiful and the regulators don’t push for soil conservation. However, alternatives are available to treat the soil and conserve it. This talk will give an overview of Earthmaster’s PEPSystems® bacteria/plant technology as a method for treating contaminated soil to conserve it. The talk will review the treatment strategies used at several sites across western Canada, highlighting the versatility of phytoremediation for soil treatment. The economics of using PEPSystems to treat soil will be discussed along with the methods developed for predicting soil treatment timelines.

    Survey of PFAS Compounds in Edible Fish Species in Canadakeyboard_arrow_down

    Heather Lord, Manager, Environmental R&D for Bureau Veritas Laboratories discusses studies related to the levels of PFAS present in various fish species typically consumed by humans. This presentation will describe:

    • The methods used to analyse PFAS in tissue samples relative to other solids
    • Types and amounts of PFAS found grouped by species, habitat preference and source location
    • Potential consumption advisories for different groups according to developing guidance

Conceptual Site Model – Introduction


Why are we doing this?

The objective of GeoEnviroPro Talks is to further support the application of solid environmental science in the real world, and to introduce new concepts to solve old problems. We want to build a community of contaminated site practitioners and look forward to helping you on your professional journey.

Some of BC’s most experienced remediation practitioners, including Dr. Reidar Zapf-Gilje and Hydrogeologist Guy Patrick, are pulling together over 104 years of cumulative experience to have some frank, honest, focused talks on critical issues to practicing professionals today.

We’ll spend ½ hour each week presenting and discussing important and interesting topics with you – topics relevant to environmental professionals. New technical tools (and some old ones!), regulatory issues, case studies, remediation, emerging (and emerged!) contaminants, and risk assessment. We promise to include time for dialogue and questions.
