We are in the process of redeveloping the GeoEnviroPro website!

If you have trouble finding resources or information on our site in the meantime please email info@geoenviropro.com.

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!!

    Occurrence and Migration of PFAS ‘Forever Chemicals’ in Surface Water and Groundwaterkeyboard_arrow_down

    This presentation will consist of several video animations and associated discussion of groundwater and surface water contamination by the recently publicized PFAS chemicals referred to as "forever chemicals".Attendees to the presentation should expect to gain a mental model of how firefighting foam, a major source of PFAS, impacts these water resources.

    Treating Soils In Place – An Alternative to Excavationkeyboard_arrow_down

    This presentation explores recent developments for treating contaminated soil and groundwater in place with the goal of identification of better and lower cost solutions to accomplish your clients’ objectives. 

    The presentation will provide an overview of recent technology including thermal desorption, vapour extraction, pump and treat, bioremediation, chemical reduction or oxidation, surfactant flushing, horizontal wells, sorption and stabilization additives.  The discussion will focus on the pros and cons of these various approaches and how consultants can obtain the necessary information to provide to their clients as part of the remediation option analysis.

    Experience Using Aerial Drones for Pit Lake Water Sampling and Quarterly Monitoring.keyboard_arrow_down

    The successful prediction and management of mine pit lake water quality is best accomplished through routine, frequent water sampling. Typically, sampling is performed using boats, however, boat sampling subjects personnel to multiple health and safety risks. New water sampling techniques using aerial drones eliminate health and safety risks, reduce the cost of sampling, and can also increase the frequency of data acquisition leading to better lake management.The method has been published, approved by some regulators, and applied at over 21 pit lakes in the USA and Canada. This presentation introduces the equipment and methodology, and provides a detailed case study from the Thompson Creek Mine Pit Lake in Idaho, USA from 2018 to 2020.

    Who’s in charge, you or the data? Simple visualization approach to assess remediation performancekeyboard_arrow_down

    Success in remediation is based on the numbers. One of the greatest challenges, especially to alternative remediation methods, is the demonstration of “certainty”. A vast set of numbers in a table format can sometimes be one of the hardest ways to present both the success and limitations of a treatment process.Using simple statistics tools such as box and whiskers, error bars, standard deviations, etc., allows a complex set of data to be visually presented quickly. This is a highly effective method to determine remediation performance over time and also can be very powerful in planning which remediation techniques to employ, or which not to. During the presentation, various sets of data will be used to present ideal remediation situations as well as others that presented challenges. We will also review how data that is collected purposefully and intentionally can get the programs back on track or provide early warning that changes in treatments might be needed.

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.
