On December 8, 2011, University of Arizona Superfund Research Program (UA SRP) investigators Dr. Eric Betterton and Dr. Raina Maier delivered a seminar at US Environmental Protection Agency (EPA) Region 9 headquarters in San Francisco, CA. Dr. Betterton discussed his work characterizing wind-blown dust at mining sites in Hayden and Dewey-Humboldt, AZ, including size fractionation of particles and chemical speciation of associated metal contaminants. Dr. Maier discussed her phytoremediation field trial at a Superfund mining site in Dewey-Humboldt, AZ, and presented data on chemical, physical, and biological changes occurring at the mine tailings as successful plant growth occurs. The seminars were reprised for an expanded audience via the US EPA CLU-IN website on January 11, 2012, and can be viewed online.
The EPA-SRP Seminar Series is designed to bring together SRP researchers with US EPA Remedial Project Mangers in the Pacific Southwest (EPA Region 9). Each topic is presented as a “Live at 9” seminar at Region 9 headquarters in San Francisco, followed by an international web seminar sponsored by NIEHS and broadcast via the EPA CLU-IN website. In this 4th season of the series, developed by Sarah Wilkinson, UA SRP Research Translation Coordinator and Mike Gill, US EPA Region 9 Superfund and Technology Liaison, seminars are being designed to present two facets of a common issue.
