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.

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!!

    Estimating the Long-Term Capacity of a Production Wellkeyboard_arrow_down

    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.

    An Interactive Training System for Reduction in Cost and Complexity of Remediation and Long-Term Management of Contaminated Siteskeyboard_arrow_down

    Site investigation, monitoring and management programs for complex sites are often cumbersome, over- or under-designed, and often contain unknown levels of uncertainty.  In addition, the transition from active remediation to long term monitoring is a process of rationalizing and balancing cost, protection of human and ecological health, envelopes of uncertainty, and (often conflicting) stakeholder inputs.  This ESTCP project was proposed as a follow-on to the SERDP-funded DIVER project (Data Information Value to Evaluate Remediation – ER-2313) which is developing technical guidance on the value of information for site investigation, remediation and monitoring programs to reduce life cycle costs for complex sites.  Building upon DIVER, this ESTCP project developed a web-based interactive training tool for environmental monitoring and performance optimization (TEMPO – Training for Environmental Monitoring Performance Optimization) that incorporates training on the design and review of monitoring systems for performance assessment, site investigation approaches to optimize existing remedial systems, and monitoring programs for long term compliance. Dr. David Reynolds is an Ontario-based Senior Principal with Geosyntec consultants and manages the company’s Australian operations.  Dave’s practice has a focus on research and development, particularly in the areas of site investigation and remediation.  Dave has over 20 years of consulting and academic experience, ranging from fundamental bench-scale studies, to phenomena and field-scale modeling, to full-scale remediation of LNAPL and DNAPL sites.

    Considerations for Investigation and Remediation of Contamination in City Streetskeyboard_arrow_down

    There is a wide range of factors to consider when planning for and conducting contaminated sites investigation or remediation projects in City streets. Based on her experience as an environmental consultant, land owner’s representative, and regulator, Jennifer Mayberry will provide insight into the expectations of local governments and key considerations for investigation, physical remediation, and risk assessment of contamination in City streets. Jennifer Mayberry  is an environmental scientist with a Bachelor of Science degree from the University of Western Ontario. Jennifer has over 16 years of experience in contaminated sites assessment, remediation, human health and ecological risk assessment, and management working as an environmental consultant, as an advisor on sustainability and environmental projects for a federal government department, and as the environmental manager for a large local government. Jenn has a strong background in contaminated sites, hazardous materials, environmental protection, environmental emergency response, waste reduction and diversion, environmental policy development, and managing regulatory enforcement and compliance

    Comparing Data to Standards Using Statistics: Why and Howkeyboard_arrow_down

    Many regulations compare a mean or percentile of observed data to a standard or guideline.  If the mean exceeds the standard, the soil/water being sampled is out of compliance.  If more than an allowed percentage (say 10%) of observations exceed the standard, the soil/water is out of compliance.  Such comparisons lead to elevated false positives, false statements of non-compliance.  The statistical approach compares a confidence limit on the mean or percentile rather than the parameter itself to the standard value.  Why should a confidence limit be employed?  What are the drawbacks to using the observed mean or percentile?  After answering these questions, the method for comparing a confidence limit to a standard is illustrated.

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.
