Nicholas Head, Ainsley Inglis, and David Reynolds’ Co-Authored EK-TAP Paper Published in Water Research Journal

Nicholas Head (Guelph), Ainsley Inglis (Guelph), and David Reynolds, Ph.D. (Sydney) co-authored "Field Test of Electrokinetically-delivered Thermally Activated Persulfate for Remediation of Chlorinated Solvents in Clay", recently published in the International Water Association (IWA) Water Research Journal.

Nicholas, Ainsley, and David's co-authors are Jason I. Gerhard and Ariel Nunez Garcia from the University of Western Ontario, Ahmed I.A. Chowdhury from the Bangladesh University of Engineering and Technology, Cjestmir V.de Boer from the Netherlands Organization for Applied Research, Audrey Sidebottom and Leanne M. Austrins from Dow Chemical, Jake Eimers from Jacobs, and Denis M. O'Carroll from the University of New South Wales.

The paper presented a field-scale study which investigated the novel approach of applying electrokinetics (EK) to enhance the delivery of persulfate in a low-permeability media and the ability of electrical resistance heating (ERH) to thermally activate the delivered persulfate.

Nicholas is a Staff Geologist based in Guelph with experience in both site investigation and remediation involving challenging chlorinated solvent impacted sites. He has experience implementing and evaluating a wide range of remedial technologies both at the laboratory and field scale with a research background in electrokinetics and in-situ chemical oxidation. His experiences also extend to soil vapor intrusion assessment and mitigation.

Ainsley is a Staff Scientist based in Guelph with experience in vapor intrusion, electrokinetics, in-situ chemical oxidation with thermally activated persulfate, in-situ chemical reduction with zero valent iron, and enhanced in-situ bioremediation. She has experience in performing field studies, site characterization, laboratory analysis, engineering calculations, data management, sample collection, and technical writing.

David is a Senior Principal Engineer based in Sydney with more than 20 years of experience specialized in the development and implementation of groundwater remediation technologies and management strategies for complex sites with challenging hydrogeological conditions. He is the Australian Operations Manager for Geosyntec.
