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!!

The Permeable Reactive Barrierkeyboard_arrow_down
A rerun of last winter's webinar - Since everyone seems to be including PRBs in their remedial options assessments (usually by asking an innocent, guileless contractor to do a free "budgetary" estimate), let's take 20 minutes to review how they work, how you build them, and what drives the costs.

Re-purposing Soil Contamination at the Source Site: Case Studieskeyboard_arrow_down
The use of conventional ‘dig and dump’ as a sole method for soil remediation has been on the decline for some time. In British Columbia, the majority of sites are now being remediated using risk-based methods. For sites with contaminated soil, this means that contamination is now often being managed in place. As an extension to strict in-situ soil management, certain sites are amenable to purposeful re-location and consolidation of waste soils, often in conjunction with site redevelopment. This talk will present on how consolidation of waste soils can be achieved at sites when supported by risk assessment. Three case studies will be presented illustrating a range of examples where this approach has been applied. Bio: Stefan Quaglia has been conducting Human Health and Ecological Risk Assessments (HHERAs) throughout BC at Contaminated Sites for over 18 years. In 2013 Stefan started a consulting firm, Trillium Environmental, specializing in providing risk-based solutions. He is a registered professional biologist and a CSAP Risk Assessment Approved Professional in BC. Stefan has enjoyed the opportunities he has had to work with a wide range of talented professionals to develop risk-based remediation solutions at contaminated sites.

Groundwater Quality vs Groundwater Quantity: An Emerging Industrykeyboard_arrow_down
Well installation and annular seal construction techniques that are widely accepted may not be working as constructed. The importance of isolating the primary producing aquifer cannot be stated strongly enough - an effective annular seal above and below the aquifer needs to be established. For any new well construction or well rehabilitation, the importance of understanding the complete hydrostratigraphy cannot be understated. It is and never should be a question of groundwater quantity over groundwater quality. Proper and effective well workover technique includes the incorporation of a thorough evaluation of well construction details, borehole geophysical logs, geochemistry of the aquifers penetrated, and historical well data. This talk continues the discussion on being the solution - help preserve groundwater and the future of the industry. This issue and corresponding corrective actions represent new business opportunities/markets for the established water well professional. BIO: Bruce Manchon is a California, Nebraska and Texas Professional Geologist with over 35 years of professional experience in the environmental and petroleum industries. He received a B.A. in geology from the University of Colorado and is a senior hydrogeologist and owner of Janeil Environmental Solutions in Boulder, Colorado. Currently, he is responsible for oversight of the technical aspects within the project scope relating to geology and hydrogeology, remediation and ensuring that the technical objectives of the scope of work are met for a variety of commercial clients. Bruce has direct experience with metals contaminated soil and ground water projects in many varied hydrogeological settings, including sand and clay terrains as well as karst (epikarst), hard rock and fractured rock environments. Scope of experience includes field investigation, extensive hydrostratigraphic analysis to define the effects of hydrogeology on contaminant fate and transport, geochemistry and contaminant recovery for vadose and saturated zone remediation programs. Bruce is part of a team in Nebraska, that is evaluating municipal wells for the improvement of groundwater quality.

A new COC for automotive repair shop & gas bar that has a COC from 1999 – Case Studykeyboard_arrow_down
Prior to purchasing a property, the prospective buyer requested confirmation that there were no outstanding environmental liabilities associated with the current and historical site operations. Although the site had a CoC from 1999, investigation of the site to today’s standards identified a wide range of contamination in various media resulting from changes in regulations and practices in the intervening two decades. This case study illustrates how many unknowns could be associated with a Site that is already considered as officially remediated due to the issuance of a CoC in the past.
