Michael Healy, (Ontario) will present “Bench Scale Studies: Lessons Learned for Informing Field Demonstrations” and Sandra Dworatzek will lead the Interstate Technology and Regulatory Council (ITRC) Training Workshop “A New Understanding of 1,4-Dioxane Risk and Treatment” at Remediation Technology (RemTEC) Virtual Summit.

Michael’s co-presenters are Sandra Dworatzek, Phil Dennis and Jeff Roberts from SiREM.

Michael is the Treatability and SP3™ Services Coordinator at SiREM with seven years of experience. Michael has managed numerous bench-scale studies evaluating remediation technologies for contaminants including chlorinated solvents, petroleum hydrocarbons, emerging contaminants and other recalcitrant compounds in soil, sediment, and groundwater. Michael has several years of passive sampling experience and was a lead member in the development and commercialization of the SP3™ sampler.

Sandra is a Principal Scientist with more than 25 years of experience in bioremediation of chlorinated solvents, petroleum hydrocarbons, emerging contaminants, and other recalcitrant compounds. She has specific technical experience in the design of laboratory treatability studies, the scale up of growth of aerobic and 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. She currently provides senior technical oversight of laboratory treatability studies and the development and scaleup of new bioaugmentation cultures, including novel cultures for BTEX compounds under anaerobic conditions and aerobic 1,4-dioxane bioremediation. Sandra currently is the industry lead on a Genome Canada funded project for the commercialization of anaerobic BTEX degrading cultures.
The RemTEC Virtual Summit delivers a truly unique platform focused on advancing the environmental science and remediation industry. It is the place where you can hear essential sources of information on technology, application and policy affecting contaminated site restoration field from the world’s leading experts within the academic, regulatory and environmental-consulting communities. By daring to be different and distinctively focusing on the quality – not quantity – of topics, session chairs, presenters and posters, RemTec has created the most advanced forum where knowledge sharing, and innovative thought leadership come together and pave the way to progress.
Association partners for RemTech include: The Cooperative Research Centre for Contamination Assessment and Remediation of the Environment (CRC CARE) and the ITRC. CRC CARE is an independent organization that performs research, develops technologies and provides policy guidance for assessing, cleaning up and preventing contamination of soil, water and air. The (ITRC) is a state-led coalition working to reduce barriers to the use of innovative air, water, waste, and remediation environmental technologies and processes. ITRC produces documents and training that broaden and deepen technical knowledge and expedite quality regulatory decision making while protecting human health and the environment. With public and private sector members from all 50 states and the District of Columbia, ITRC truly provides a national perspective.


Bioremediation is increasingly evaluated and applied at sites where there are many challenges to achieving remediation success. It is important to understand the types of challenges encountered and potential solutions prior to field implementation, in many cases, bench-scale treatability testing has proven invaluable in identifying the conditions compatible with bioremediation success or alternatively where bioremediation is unlikely to succeed.   A growing body of knowledge from both laboratory treatability testing and field applications provides insights into opportunities for successful bioremediation at field sites. This presentation will provide examples of bench-scale treatability tests that were conducted prior to field implementation and discuss the lessons learned and project outcomes.

ITRC Training Workshop: A New Understanding of 1,4-Dioxane Risk and Treatment will be led by Sandra at 3:45 on Thursday March 11. The Interstate Technology and Regulatory Council (ITRC) is a state-led coalition working to advance the use of innovative environmental technologies and approaches. The ITRC 1,4-dioxane team is composed of subject matter experts from public and private sectors who produced factsheets and a guidance document on the challenges associated with 1,4-dioxane and best practices in addressing it. This live virtual training presented by the ITRC 1,4-dioxane team experts will provide information, based on the latest research and regulatory updates, on the risks of 1,4-dioxane and best management practices associated with characterization and treatment.
