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.
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!!
How Drones Add Value to Contaminated Sites Projects and Mine Environmental Assessmentskeyboard_arrow_down
The emergence of reliable, accessible, and affordable Unmanned Aerial Vehicles (UAVs) in recent years has led to many new opportunities for creative applications of these technologies. UAVs, also known as drones, are becoming more common and more popular, and there is a growing body of literature demonstrating the use of digital aerial imagery and photogrammetry for scientific purposes. Golder has identified many effective uses of drones for contaminated sites and mining applications, and four example applications are discussed in this presentation.These examples are just some of the possible uses of drones for contaminated sites and mining applications and show how coupling aerial imagery from drones with geographic information system (GIS) software can enable an effective, safe, relatively rapid and low-cost means of improving existing field techniques.
This Webinar is based on CANADIAN experience and law with a focus on British Columbia. The science, however, is universal and the laws and regulations tend to be similar.In BC, if groundwater at a site contains a substance that exceeds the applicable CSR standard, the Site is not a contaminated site if the substance concentration is less than background.Background concentrations for a Site can be established using either:
- Protocol #9 – Determining Background Groundwater Quality, or
- Technical Bulletin #3 – Regional Background Concentrations for Select Inorganic Substances
Global warming and sustainable development are vital issues for our world. Similar to other sectors, an important and emerging question facing the environmental remediation industry is how to integrate the principles of sustainable development. These principles are often summarized in relation to the triple bottom line, which encompass environmental, social and economic factors.This presentation will summarize ways in which sustainability can be incorporated in environmental projects through best management practices and by integrating sustainability indicators into the planning and decision-making processes as laid out in a new Toolkit of Remediation Technologies being developed for Contaminated Sites Approved Professional Society of British Columbia and Shell Global. A roadmap for sustainability evaluations is presented that includes consideration of technical feasibility together with the triple bottom line.

This presentation is devoted to one of the most basic, but also one of the most important, assignments of a hydrogeologist: estimation of the long-term capacity of a production well. Assessing the capacity of a well is not something a hydrogeologist wants to get wrong, but there are plenty of opportunities to do so. The presentation will begin with the distinction between the capacity and the sustainable yield of a production well. The discussion will then move on to a consideration of the two components of the capacity calculation, the allowable drawdown and the specific capacity. Simplified methods of estimating the specific capacity will be reviewed, followed by a more complete examination of the factors that control the drawdown in a well. The role and interpretation of step tests will be highlighted. The presentation will conclude with cautions regarding the extrapolation from short-term tests to predictions of long-term well performance. A set of detailed notes has been prepared to accompany the presentation.
Mr. Neville has over 15 years of experience as a groundwater hydrologist, with particular emphasis on quantitative analysis of groundwater flow and solute transport. He has experience in the synthesis of hydrogeologic data, the evaluation and protection of groundwater resources, and the analysis and design of remedial measures. Mr. Neville has extensive experience in the development of work plans for groundwater projects. He has developed and documented large-scale three-dimensional numerical models for industrial, mining, and government clients, and has reviewed numerous site-specific hydrogeologic analyses and groundwater modeling codes. He is responsible for the testing, documentation, and support of groundwater modeling software at S.S. Papadopulos & Associates, Inc. Mr. Neville has developed and taught professional short courses through S.S. Papadopulos & Associates, Inc. and the International Ground Water Modeling Center. Mr. Neville also assists in teaching graduate courses at the University of Waterloo in groundwater resources evaluation, solute transport, and analytical solutions.

Don’t Forget to Look Up…or Down! Some things to think about when assessing groundwater flowkeyboard_arrow_down
This presentation highlights the importance of assessing vertical groundwater flow in order to properly delineate groundwater contamination, effectively assess the fate and transport of dissolved contaminant plumes, evaluate applicable water use standards, and develop effective remediation plans. A description of characterization requirements and examples will be provided to highlight the importance and benefits of assessing vertical groundwater flow.
