Presentation Overview:

"Contaminated Land: Applications in Real Environments" (CL:AIRE), a not-for-profit UK organization, is presently undertaking a research project on behalf of the Department for Environment, Food and Rural Affairs (DEFRA), titled "A risk/benefit approach to the application of iron nanoparticles for the remediation of contaminated sites in the environment", supported by r3 Environmental Technology Ltd (UK), The University of Nottingham (UK), Deltares (Netherlands) and Geosyntec (USA).

This project and the U.S. EPA's Technology Innovation and Field Services Division are planning to run a webinar as part of this project.

The purpose of this webinar is to hear presentations from some site remediation projects where nanoscale zero-valent iron has been used as a remediation technique in a practical way. Presentations will discuss the context of the application, the risk management problem being addressed, the practical delivery and use of the technology, the regulatory approval process, and the project outcomes and ongoing monitoring. In particular, a focus of the webinar will be to consider the risks versus the benefits of iron nanoparticle use for remediation, and this will be the focus of an open discussion following the project presentations.
