We are in the process of redeveloping the GeoEnviroPro website!

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!!

    GeoPro Talks – An Introduction to Risk Assessment As A Remedial Approach for Contaminated Siteskeyboard_arrow_down

    Seven key risk assessment concepts will be discussed in addition to regulatory context and some history.

    GeoPro Talks – Northern Metals Contamination: Digging Deeper to Evaluate the Risk of Metals Contamination in Soilkeyboard_arrow_down

    The presentation is a case study on an investigation program completed on a large residential development property in a northern community. The investigations required incorporation of some less common techniques for analysis, in order to accurately evaluate risks at the site from elevated metals.The presentation will include an overview of the staged approach used, hurdles that were encountered, and solutions that were implemented to serve the clients needs.

    GeoPro Talks – Chlorinated Solvents – Tips, tricks and tragedieskeyboard_arrow_down

    Investigating chlorinated solvents like they are petroleum hydrocarbons can result in poorly performed investigations, incorrect conclusions, the degradation of site conditions and the potential for increased liability on the consultant.   Given the complex ways chlorinated solvents move in the environment, it is not uncommon for contaminant plumes to be missed and for a consultant to report a contaminated site as clean.  Far worse, certain commonly applied investigation techniques can drive chlorinated solvents into deeper aquifers that were previously uncontaminated.  Thus, the investigation itself can exacerbate the on-site conditions and increase the costs to remediate.This presentation will discuss the key principles that should be used during the development of a chlorinated solvent investigation strategy.  The principles discussed will include, drilling methodologies, the placement of monitoring points, the depths of samples, the environmental media sampled, and the materials used to construct groundwater wells.  Differences between the principles applicable in a hydrocarbon investigation and a chlorinated solvent investigation will be highlighted, with an explanation of the science behind these differences.

    GeoPro Talks – Radon Awarenesskeyboard_arrow_down

    Radon is a radioactive gas that occurs naturally when the uranium in soil and rock breaks down. It is invisible, odourless and tasteless. The gas moves through the ground and can enter buildings, with the potential to accumulate to levels which pose a risk to the building occupants health. Because there are so many factors, it is not possible to predict the radon level in a building. Therefore, only way to know for sure is to test and the only way to reduce the levels is through mitigation.

    GeoPro Talks – In situ Salt Remediation of Soilkeyboard_arrow_down

    The choices for remediating salt contaminated soil are limited. Often, excavating contaminated soil and placing it into a landfill facility is the only option. Depending on location and the amount of contamination, this is not always practical or economically viable.The presentation will review some of the options available for in situ remediation of salts in soil, including a look at case studies involving Earthmaster’s PEPSystems® bacteria/plant technology as a sustainable method for treating contaminated soil and conserve it. The economics of using various methods to treat soil will be discussed along with the carbon benefits of leaving soil in place and treating it.

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.
