Prof. Thomas Sheahan, Training Core Leader, will be presenting at the Fall/Winter 2010 edition of Risk eLearning, entitled “Contaminated Sediments: New Tools and Approaches forin situ Remediation.” This Webinar is presented by the Superfund Research Program (SRP), in collaboration with the US Environmental Protection Agency’s Office of Superfund Remediation and Technology Innovation (OSRTI).
The webinar will be on November 17, 2010 from 2:00 – 4:00pm ET
12/9/10 Update: A complete archive of this seminar is now available for free download and replay at: http://www.clu-in.org/live/archive/.
In addition to Prof. Sheahan, this seminar will also feature SRP grantee Dr. Peggy O’Day (University of California – Merced) and will be moderated by Karl Gustavson (US EPA). Dr. O’Day will present an overview of different types of reactive amendments, mechanisms and chemistry associated with contaminant sequestration, examples of recent applications, and opportunities for the use of new materials and delivery methods. Dr. Sheahan will describe a bench-scale experimental study to examine the efficacy of the reactive geocomposite mats or overlays (RCM) to isolate and partially remediate PCB- and PAH-contaminated sediment, and to provide sufficient sequestering functionality to minimize biouptake by organisms in clean sediment overlying the RCM. He will present the results from a series of tests on spiked natural sediment using a new device developed for this research, the Integrated Contaminated Sediment Testing Apparatus Column (ICSTAC).
