Using Geology to Follow the Groundwater: Follow the Flow to Successful Remediation
First broadcast: November 15, 2017
Speakers: Rick Cramer, PG, CA Remediation Department Manager at Burns & McDonnell and Craig Sandefur Vice President of Remediation Applications Development at REGENESIS
Recording Available| In this webinar we are pleased to have as a special guest speaker Rick Cramer, CA Remediation Department Manager at Burns & McDonnell(USA). His presentation will demonstrate Environmental Sequence Stratigraphy (ESS), an established methodology that significantly reduces the uncertainty and provides the framework for characterising contaminant migration pathways and defining the conceptual site model (CSM).
Examples will be presented that show the efficacy of ESS as a critical path to complex site investigation and remediation. The methodology has been successfully applied at numerous complex contaminated groundwater sites throughout the US, including over 25 US Department of Defense (DoD) facilities. The case studies will provide examples of best practices in applying geology to CSMs and provide “rules of thumb” to test the efficacy of your CSM.
Certificates of Attendance can be made available (that may contribute to CPD). Please email your request for you and your colleagues to europe@regenesis.com.

Multifunctional Amendments and Site Characterisation Effectively Manage Back Diffusion from a Fractured Sandstone Aquifer
First broadcast: June 27, 2017
Speakers: Matthew Burns, Technical Fellow at WSP
Recording Available| Fractured bedrock aquifers can be extremely heterogeneous which not only results in complex dissolved plume behavior but can also hinder in situ remediation efforts that rely on subsurface injection of amendments to promote microbial activity and abiotic degradation. Simply put, injected amendments may bypass or have limited contact time with impacted zones due to transport differences within primary and secondary rock porosity and other subsurface heterogeneities. With thorough characterization of site hydrology, novel amendment formulations, routine performance monitoring, and an adaptive site management approach however,in situ remediation can be successful in fractured bedrock aquifers.
In this webinar we are pleased to have as a special guest speaker Matthew Burns, Technical Fellow and the in situ remediation Practice Leader for WSP. He presents a case study of a site where multifunctional amendments were applied to manage back diffusion of chlorinated VOCs from a fractured sandstone aquifer. He is joined by Maureen Dooley, Director of Strategic Projects at REGENESIS.

Expert Remediation Consultant Panel: The Four Cornerstones of a Successful Groundwater Remediation Project
First broadcast: June 26, 2018
Speakers: Jeff Carnahan, President, EnviroForensics & PolicyFind and Keith Gaskill, Chief Geologist, EnviroForensics will join Barry Poling and Doug Davis of REGENESIS
In this webinar we are pleased to have a panel of remediation experts who each bring unique expertise, background and skill sets to a discussion on remediation best practices. Jeffrey Carnahan and Keith Gaskill of EnviroForensics® join Barry Poling and Doug Davis of REGENESIS® for a presentation on the cornerstones of a successful groundwater remediation project. The four essential cornerstones to building a successful groundwater remediation approach are:
- Dynamics
- Diversity
- Certainty
- Affordability
In some less complex scenarios, one or more of these cornerstones may play a lesser role than the others. But, when dealing with more complicated sites, like those with chlorinated solvents or complex geological conditions, each cornerstone demands equal attention to ensure the completion of project objectives. During this webinar presentation, we explain how Dynamics, Diversity, Certainty and Affordability can individually, and jointly, impact the overall project success. Real world examples are used to highlight important points, and to demonstrate how EnviroForensics and REGENESIS managed a high-profile remediation project at a chlorinated solvent release by having all four cornerstones firmly in place.

Case study: Demonstrating success with PlumeStop and colloidal ZVI – with Matt Burns of WSP
First broadcast: May 30, 2018
Speakers: Matthew Burns, Technical Fellow WSP
Recording Available| We are pleased to have guest speaker Matt Burns, Senior Fellow at WSP present this live, international webinar. He will present PlumeStop® and colloidal ZVI (cZVI) treatment case studies and practical analytical strategies used to demonstrate destructive treatment.
Stimulating biodegradation of chlorinated VOCs on activated carbon and direct abiotic treatment of using reduced metals such as ZVI are not new to the remediation industry and have proven to be highly effective when direct contact is made. However, the colloidal solid composition of these materials severely limits efficient in situ application at most sites.
The steric stabilization chemistry behind the Regenesis products PlumeStop and cZVI eases delivery challenges and dramatically widens the applicability window of these amendments to include most sites where in situ remediation is contemplated. These transformational amendments bring a unique set of regulatory and performance monitoring challenges when discerning desirable destructive processes from often unacceptable non-destructive mechanisms.

A Multi-Site Performance Review of Slow Release Electron Donor and Bioaugmentation Co-Application Strategy
First broadcast: 25 August 2016
Speakers: Steve Sittler, P.G., Senior Project Manager, Patriot Engineering and Environmental
A strategy for co-application of electron donor and bioaugmentation, as well as a multi-site performance review drawing lessons learned for achieving best results, will be the focus of this webinar. We are pleased to have with us Mr. Steven Sittler, P.G., Senior Project Manager at Patriot Engineering and Environmental. Mr. Sittler has more than 30 years of technical experience in applied hydrogeology, with specialized experience in remedial strategy development and implementation.
Mr. Sittler presents strategies for success using co-application of electron donor/bioaugmentation. Recent technological advancements have faciliated a transition towards co-application of controlled-release electron donors and bioaugmentation cultures of Dehalococcoides sp. (DHC). These advancements, including pH neutral electron donors and improved understanding of the viability of DHC, have allowed changes to the old way of thinking of waiting to bioagument. The result is a more aggressive approach with a significant increase in enhanced reductive dechlorination (ERD) rates. Use the form on this page to view this webinar recording today.
