SiREM continues our Webinar Series and our 20th anniversary celebration with a look back on some of the initial bioaugmentation projects that occurred in the South East, USA. As early adopters to the application of anaerobic bioremediation, Jim Langenbach and Rebecca Daprato will share insights into their bioremediation experience in the early days and how it has advanced over the last 20 years using site case studies of field-scale bioremediation applications. Phil Dennis will highlight SiREM products and services related to bioremediation and discuss some exciting technology advancements that lie ahead.

We hope you will join us as we continue our 20th Anniversary Celebration:

Abstract:

The application of bioremediation to address chlorinated volatile organic compounds (CVOCs) has evolved substantially over the last 20 years.  As the electron donors, microbial cultures, microbial testing capabilities, and delivery methods have advanced in concert with the development of robust conceptual site models, so have the strategies for the successful anaerobic bioremediation of CVOCs.  This presentation will focus on the tools and techniques applied to early CVOC bioremediation applications and how they have evolved over time as characterization strategies have improved using case studies of field-scale bioremediation applications at sites.

The Presenters

Jim Langenbach, P.E. Senior Principal, Geosyntec Consultants. 

James Langenbach is a Senior Principal Environmental Engineer based in Florida with over 30 years of experience focused on assisting clients with environmental assessments; remediation design and treatment system optimization; environmental management systems; sustainable remediation designs; and regulatory compliance. For decades, a wide range of industries have used chlorinated solvents as degreasing agents and for similar commercial applications. In many places throughout the world, these solvents have seeped into the ground near work sites, either through spills or as runoff, creating dense plumes of contaminants that can threaten aquifers and ecosystems. Jim is at the forefront of practitioners developing novel solutions to these issues in this field. As a consultant, Jim is recognized for using innovative approaches in the planning and execution of projects that are grounded in practical applications of existing and emerging technologies.

 Rebecca Daprato, Ph.D., P.E. Senior Principal, Geosyntec Consultants. 

Rebecca Daprato is a Senior Principal Environmental Engineer based in Colorado with more than 15 years of professional experience focused on groundwater and soil site assessments; remedial alternative evaluations; remedial system design, construction, operation, and optimization; vapor intrusion; and the design, installation, optimization, and operation of leachate treatment systems.  One of her areas of expertise is the evaluation and implementation of bioremediation applications for the remediation of chlorinated solvent impacted groundwater, including the application of molecular techniques to evaluate dechlorination potential and extent. Rebecca helps clients resolve complex issues associated with soil and groundwater contamination and provides regulatory compliance support.  Rebecca has worked for industrial, commercial, municipal, and federal clients under state-mandated and voluntary programs, and the U.S. EPA RCRA and CERCLA programs.
