Jeff Roberts (SiREM Operations Manager) will be presenting at the educational short course titled “Optimization and Monitoring for Remediation of Chlorinated and Related Compounds” along with speakers from Tersus, Eurofins and Ellingson. Jeff’s is excited to present on “Advances in Enhanced Anaerobic Bioremediation of Recalcitrant Chemicals” and discuss bioremediation further with attendees. The half-day short courses are in Toronto, ON (September 12, 2023) and in Buffalo, NY (September 13, 2023).

Jeff Roberts, M.Sc. Earth Sciences, University of Waterloo. Jeff is the Operations Manager at SiREM with extensive technical experience in the laboratory assessment and field implementation of soil, sediment and groundwater remediation technologies at sites containing contaminants including chlorinated solvents, petroleum hydrocarbons and other recalcitrant compounds. Over the past twenty years he has conducted and managed hundreds of bench-scale batch and column treatability studies and also has technical experience in the growth, scale up and field implementation of several anaerobic microbial cultures for bioremediation remedies. Jeff has several years of passive sampling experience and was a lead member in the development and commercialization of the SP3TM, SPeeperTM and PFASsiveTM samplers.

Remediation Seminars offers Short Courses on various topics related to soil and groundwater remediation throughout the year. Courses are open to our sponsors clients and guests from within the groundwater remediation community. We know that NOT all educational events are created equal. Our short courses are taught by people who really know in situ remediation and are eager to share their knowledge with you. At our events you will connect directly with industry leading practitioners as they highlight the latest ideas for contaminant source area delineation, bioremediation and sustainable remediation technologies.

Abstract – Advances in Enhanced Anaerobic Bioremediation of Recalcitrant Chemicals

Bioaugmentation with dechlorinating cultures such as KB-1® and KB-1 Plus, is an established remediation technology for the enhanced anaerobic bioremediation of chlorinated solvents. While Dehalococcoides (Dhc) are well known solvent dechlorinators, other dechlorinators including Dehalobacter, Geobacter and Dehalogenimonas, provide further dechlorination capabilities. Gene-Trac® testing for this wider range of dechlorinators, both before and after bioaugmentation, provides a more complete picture of site remediation processes.

SiREM has contributed to significant advances in characterizing of anaerobic benzene, toluene and xylene (BTX) biodegraders, development of bioaugmentation cultures (DGG-Plus™) and developing Gene-Trac® tests to monitor these processes in situ. These tools provide bioremediation solutions at gasoline and other BTX contaminated sites where traditional aerobic remediation approaches are not.

Bioremediation for chlorinated solvents and BTX compounds is one of the lowest cost options and bioaugmentation has the potential to decrease remediation time frames and increase the range of sites to which bioremediation is applicable. This presentation will discuss recent advancements in bioaugmentation cultures, molecular biological tools and provide case studies where bioremediation was the remedy of choice at chlorinated solvent and petroleum hydrocarbon sites.
