This webinar is a result of Recommendation 9 of EPA's Superfund Task Force, which encourages the Superfund program to "utilize state-of-the-art technologies to expedite cleanup." Actions under this recommendation include expanding the use of new remediation technologies and approaches to address contaminated sites.

In this webinar, we will present an overview of in situ activated carbon (AC)-based remediation technology, discuss important considerations for site characterization and treatment design, and present characterizations of physical, chemical and biological processes involved in a long-term case study where reactive AC-based technology was applied.

Presenters:

Dimin Fan, Environmental Engineer, Geosyntec Consultants (dfan@geosyntec.com)
Dimin Fan is an Environmental Engineer with Geosyntec Consultants. Previously, he was as an ORISE Research Fellow with U.S. EPA, where he conducted evaluation of various innovative in situ groundwater remediation technologies for the Superfund program. One of his main research focuses at EPA was in situ activated carbon-based technologies. He has also made significant contributions to developing and improving iron-based technologies for chlorinated solvent remediation. Dr. Fan obtained a BS in environmental science from Nanjing University, China, MS in soil physics from the University of Delaware, and PhD in environmental science & engineering from Oregon Health & Science University.

Edward Winner, Assistant Director of the Division of Waste Management, Commonwealth of Kentucky Department for Environmental Protection (edward.winner@kentucky.gov)
Edward Winner has been the Assistant Director of the Division of Waste Management in Kentucky since 2016. He started his employment with the Commonwealth of Kentucky in 1999 with the Risk Assessment Branch in the Division of Environmental Services. In 2007, he became the supervisor of the Paducah Gaseous Diffusion Plant Section in the Hazardous Waste Branch. In 2011 he became the manager of Kentucky's Underground Storage Tank Branch. Edward came to state government from the University of Louisville, Lion's Eye Research Center where he had been a postdoctoral fellow. Ed has a B.A. from Tennessee Temple University, and B.S. and Ph.D. from the University of Louisville. He also pursued additional studies at the University of Louisville, Brandeis School of Law. Ed lives in Louisville with his wife Jung Ju Lee, an employee of the Presbyterian Church USA.

Katrin Mackenzie, Senior Scientist at the Helmholtz Centre for Environmental Research — UFZ, Germany (katrin.mackenzie@ufz.de)
Katrin Mackenzie is a Senior Scientist at the Helmholtz Centre for Environmental Research — UFZ in Germany, a large governmentally funded institute dedicated to multidisciplinary research on the terrestrial environment. Katrin holds a PhD in chemistry and leads the working group "Environmental Catalysis and Reductive Methods" in the Department of Environmental Engineering which is engaged mostly in water treatment and material design for particle-based in-situ groundwater treatment.

Cindy Frickle, U.S. EPA Office of Superfund Remediation and Technology Innovation (frickle.cynthia@epa.gov or 202-566-0927)
Cindy Frickle is a physical scientist with EPA's Superfund program where she reviews and propagates technical information to site cleanup professionals through Clu-In, EPA forums, and interagency channels. Prior to joining EPA, she spent time characterizing contaminated sites, coring sediments, studying microbes, and teaching. She completed her Biogeology MS and Geology BS in the University of Minnesota's School of Earth Sciences.

Jean Balent, U.S. EPA Technology Innovation and Field Services Division (balent.jean@epa.gov or 202-566-0832)
Ms Balent is on the staff of the EPA's Technology Innovation and Field Services Division where she has worked to collect and disseminate hazardous waste remediation and characterization information since 2003. Ms Balent manages the Clean Up Information Network website and actively supports online communication and collaboration resources available to EPA. She formerly worked with the US Army Corps of Engineers Environmental Engineering Division in the Buffalo District. Ms Balent was also a member of the SUNY-Buffalo Groundwater Research Group where she constructed and tested large scale models of groundwater flow. Ms Balent has also conducted research relating to the Great Lakes, environmental remediation, and brownfields re-development. She holds a Bachelor's degree in environmental engineering from SUNY-Buffalo and a Master's degree in Information Technology from AIU.
