Phil Dennis will present “Optimization of Remediation Systems using Our Expanding Suite of Molecular Tools” in The Thought Leaders Webinar Series from Tersus Environmental from 1:00 – 2:00 p.m. on September 26, 2019.

Phil is a Principal Molecular Biologist based in Ontario with more than 15 years of experience focused environmental microbiology, molecular genetic testing, enhanced bioremediation and technology commercialization. He currently directs the molecular testing services, next generation sequencing and is the innovation lead for SiREM’s research and development program. He has also played a leading role in developing relationships with many universities and serves on the Board for University of Waterloo Center for Microbial Research.

The Thought Leaders Webinar Series highlights the latest ideas for in situ remediation from the industry’s leading thinkers. The webinars will connect its viewers directly with the professionals so they can learn new techniques and strategies to boost their knowledge, benefit their bottom line and serve their clients better. All webinars are taught by in situ remediation experts and are eager to share their knowledge with viewers.

Tersus Environmental researches, develops, and commercializes innovative soil and groundwater remediation solutions through university and professional relationships in order to meet the increasing technological demands at contaminated sites. Their proven technologies help their clients reduce uncertainty, minimize risks, and achieve cost-effective results.


Characterization of microbial communities in soil, sediment and groundwater using molecular genetic tools is commonly used to assess natural attenuation, enhanced bioremediation and for ongoing site management. Molecular genetic testing is also increasingly used for determining the microbial composition of water treatment systems, assessing the presence of pathogens, and managing conditions such as microbially induced corrosion and biofouling.

As the number of identified microorganisms and functional genes continues to increase, the applications for molecular testing are amplified. For example, we now know Dehalogenimonas is capable of converting trans-DCE to vinyl chloride (VC) and VC to ethene. This means Dehalococcoides is no longer the only microbe documented to perform the final steps in complete reductive dechlorination! Furthermore, a growing range of molecular tests are available for once “exotic” microbial processes, such as anaerobic BTEX degradation, 1,4-dioxane degradation and anammox are now being used to monitor site remediation by these processes.

For whole community assessment, next generation sequencing (NGS) is revolutionizing our ability to characterize and monitor biological communities. Two major types of commercially available NGS are 16S rRNA amplicon sequencing (16S-NGS) and shotgun metagenomics. 16S-NGS provides microbial community characterization and integrating “functional analysis” into the data reporting provides an overview of the metabolic capabilities of the entire community, markedly increasing data interpretability.

The other major type of NGS, shotgun metagenomics, identifies the microbes, but also the functional genes and other biota that may influence remediation processes, including fungi, protozoans and viruses.

This presentation will provide examples of how molecular testing provides practical solutions, and insights using case studies including an MNA site, an enhanced bioremediation site, a leachate treatment system and in controlling biofouling in a water treatment system.
