About the Webinar
Hydrocarbons are toxic and widespread pollutants resulting from releases or spills of petroleum-based chemicals into the environment. Decades of research have shown that various hydrocarbons, including benzene (CâHâ), a confirmed carcinogen, can be broken down by both aerobic and anaerobic microorganisms with specialized metabolic capabilities. Benzene-degrading microorganisms are common in nature and can proliferate following a spill event.
However, as many environmental practitioners know, active benzene degradation rarely occurs at sites lacking oxygen. Are anaerobic benzene degraders simply growing too slowly to support effective bioremediation? Are they unable to establish under typical field conditions? Or are other environmental factors limiting their activity?
This webinar will highlight key findings from more than 30 years of anaerobic benzene degradation research and explore how this knowledge is now being applied at benzene-contaminated field sites across North America.
What Youâll Learn
â
Why benzene behaves differently under anaerobic conditions
â
Key breakthroughs from decades of biodegradation research
â
Newly developed anaerobic benzene-degrading cultures
â
Field case studies demonstrating successful applications
â
Practical considerations for remediation design and monitoring

Meet Your Instructors
Sandra Dworatzek, M.Sc
Principal Scientist
Sirem
Ms. Dworatzek is a Principal scientist at SiREM and an environmental microbiologist with advanced technical experience in laboratory treatability studies. Over the past 24 years she has conducted and overseen numerous bench-scale studies examining enhanced in situ remediation in groundwater. She has specific technical experience in the design of laboratory treatability studies, the scale up of growth of anaerobic microbial cultures for bioaugmentation laboratory and field pilot tests, and evaluation of aerobic and anaerobic bioremediation, zero valent iron and chemical oxidation technologies in the laboratory.

Courtney R. A. Toth, PhD
Research Associate, Department of Chemical Engineering and AppliedÂ
Chemistry at the University of Toronto
Dr. Courtney Toth holds a Ph.D. in Environmental Microbiology from the University of Calgary and has investigated anaerobic bioremediation processes alongside Dr. Elizabeth Edwards since 2018. She has been instrumental in advancing the characterization of anaerobic hydrocarbon biodegradation processes â particularly for benzene â and led the development of first-of-their-kind anaerobic bioaugmentation cultures that degrade benzene and other BTEX compounds. Dr. Toth has received numerous awards for her work, including the Mitacs Award for Commercialization (2022) and recognition as an Emerging Professional in Bioremediation by Battelle (2025).

Elizabeth A. Edwards, Ph.D., P. Eng., O.C.
Dr. Elizabeth Edwards holds bachelorâs and masterâs degrees in chemical engineering from McGill University, Montreal, and a PhD degree (1993) in Civil and Environmental Engineering from Stanford University. She is internationally known for her work on anaerobic bioremediation, the application of molecular biology and metagenomics to uncover novel microbial processes, and the transition of laboratory research into commercial practice to develop bioremediation and bioaugmentation strategies for groundwater pollutants. She is also the founding director of BioZone, a Centre for Applied Bioscience and Bioengineering Research at the University of Toronto and a Tier 1 Canada Research Chair in Anaerobic Biotechnology. In 2016, she was awarded the Canada Council of the Arts Killam Prize in recognition of her outstanding career achievements and was appointed an Officer in the Order of Canada (Canadaâs highest civilian honour) by the Canadian Governor General in 2020.
