Geosyntec is Making Technical Contributions on PFAS and Other Emerging Contaminants to the 2019 RPIC Federal Contaminated Sites Regional Workshop in Halifax, Nova Scotia

Geosyntec professionals will be making technical contributions at the 2019 Real Property Institute of Canada (RPIC) Federal Contaminated Sites Regional Workshop taking place at the Halifax Convention Centre in Halifax, Nova Scotia on June 4-5, 2019. Additionally, Geosyntec is a workshop partner and an event sponsor.

The theme of the workshop is PFAS and Other Emerging Contaminants – The Science and Beyond.

Geosyntec contributions include five technical presentations, a poster, and participation on the main and technical committees for the workshop. Geosyntec professionals will be at the workshop to meet with attendees and answer questions about per- and polyfluoroalkylated substances (PFAS), academic partnership, emerging contaminants, remediation technologies and innovation for addressing contaminated sites.

Geosyntec Attendees

Leah MacKinnon, P.Eng (Canada)  is a Principal with over 20 years of career experience in Canada, the United States, and Europe focusing on assessment and remediation of recalcitrant compounds such as chlorinated solvents, 1,4-dioxane, perchlorate, energetics, PFAS and hydrocarbons. This work has involved collaboration with researchers in Canada, the United States and Denmark to support development of new technologies and identification of solutions for challenging sites. .

Leah is a co-author for:

  • Evan Cox's poster "Effective Treatment of Emerging Contaminants in Clay and Silt Using Electrokinetic Techniques;"
  • Matt Vanderkooy's oral presentation on June 5 in Stream 5B "Approaches to Addressing Challenges for PFAS Site Characterization in Multiple Environmental Media; and
  • Suzanne O'Hara's oral presentation on June 5 in Stream 6D "Zero Valent Zinc – A Novel Remediation Technologies for the Emerging Contaminant 1,2,3 – Trichloropropane."

For the first time, the RPIC Federal Contaminated Sites Organizing Committee has added a mentoring program to the workshop. Leah has volunteered to be a mentor to students and early career professionals during the workshop.

Tracy Dannell, H.B.Sc., EP is a Project Scientist with more than 13 years of professional environmental experience focused on contaminated sites, natural sciences, environmental regulations and compliance, at both the program and project level.

Tracy first joined a Real Property Institute of Canada (RPIC) Federal Contaminated Sites Workshop committee in 2010. Since then Tracy has participated in the main and technical committee and various other subcommittees for numerous national and regional events across Canada.

Evan Cox is a Senior Principal Remediation Scientist based in Canada with more than 25 years of experience focused on managing and directing soil and groundwater remediation projects dealing with emerging and recalcitrant contaminants.

Suzanne O'Hara, QPESA, P.Geo, P.G, is a Senior Scientist based in Canada with more than 20 years of experience focused on conceptual site model (CSM) development and remediation of groundwater and soil using innovative and more conventional technologies. Her remediation expertise includes enhanced in situ bioremediation, in situ chemical oxidization and reduction, self-sustaining treatment for active remediation (STAR) thermal remediation, passive treatment using zero valent metals, and the treatment of PCBs in building materials.

Matt Vanderkooy, P.Geo., is a Project Scientist based in Canada focused on building robust conceptual site models with the goal of supporting informed project decision making, including remedial selection and design. Matt specializes in characterizing and remediating sites involving contaminants at the groundwater-surface interface, in contaminated sediments, and identifying pathways PFAS reach receptors through multiple media.

Omneya El-Sharnouby , Ph.D. is a Senior Staff Professional based in Canada focused on developing novel nanometal based treatments for groundwater remediation from carcinogenic chlorinated organic contaminants, specifically 1,2-dichloroethane. Omneya's experience with contaminants expands to include the emerging carcinogenic contaminants, PFAS.

RPIC is known for its Federal Contaminated Sites Workshops, leading professional development events for federal and industry environmental professionals involved in the management and remediation of federal contaminated sites. These workshops offer a unique opportunity for the public, private, and academic sectors to meet and exchange new ideas and information with colleagues and industry representatives from across the country and abroad. The Halifax workshop will provide a forum for the contaminated sites community to learn about technical, scientific and organizational innovations, best practices for the management of sites contaminated with PFAS and other emerging contaminants.
