Dan Elliott Co-Authors Article on the Use of Nanoremediation in International Markets

Dan Elliott, Ph.D. (Princeton/Ewing) was a co-author of a recent article in the spring 2015 issue of Remediation magazine. The article, "Nanoremediation and International Environmental Restoration Markets," provides a risk–benefit assessment for nanoscale zero-valent iron (nZVI) based on published information and describes the steps that will be taken by NanoRem, a major European research project, as part of its work to provide a basis for better informed decision making in European environmental restoration markets.

The article states that nZVI is the most commonly used nanoremediation material, and while there has been a reasonable level of application of nZVI technologies for in situ remediation in the U.S., its utilization across Europe has been much more limited. There has been significant uncertainty about the balance between deployment risks and benefits for nanoparticles (NPs), which has affected the regulatory position in several countries. Some member states of the European Union (EU) take a strong precautionary view of the risks from the deployment of NPs into the subsurface, preventing the adoption of the technology.

Dan has been a member of NanoRem since 2012, which represents 28 individual partnering institutions such as national research organizations, problem owners (i.e., the regulated community), universities, and consulting engineering firms. With a €14 million contract overseen by the European Union headquarters in Brussels, NanoRem’s overall mission is to bring to bear nanotechnology-based tools and solutions for the cleanup of European brownfield sites.

Dan has been a contributing member of NanoRem’s project advisory group (PAG) since its inception in early 2013. His membership grew organically out of a white paper he developed entitled "A Risk/Benefit Approach to the Application of Iron Nanoparticles for the Remediation of Contaminated Sites in the Environment" with Dr. Paul Bardos of The University of Nottingham and r3 Environmental Technology Ltd, and Nicola Harries (CL:AIRE) of the U.K. Department for Environment, Food, and Rural Affairs (DEFRA). Dr. Bardos and Ms. Harries later became involved in NanoRem and recruited Dan to join the team. With Dan’s industry leading guidance in the design and implementation of nZVI for groundwater remediation, he is one of only three U.S. members of the PAG. The other two – Dr. Greg Lowry of Carnegie Mellon and Dr. Mark Weisner of Duke - are leading researchers in the burgeoning environmental nanotechnology field.
