Short description: The technical and scientific aims of the research were to undertake a search and review of publicly available literature, as well as obtaining information from other sources on the use of iron nanoparticles (NPs) in soil and groundwater remediation. The report provides an update to the Royal Society and Royal Academy of Engineering’s 2004 ‘Nanoscience and nanotechnologies: opportunities and uncertainties’ report, which recommended that there should be a precautionary approach to the release of nanomaterials into the environment, until more about the environmental impacts were known. Specifically, it was advised that the use of (free) nanomaterials within environmental applications, such as the remediation of groundwater, should be prohibited until appropriate research had been undertaken to demonstrate that the potential benefits of using nanomaterials within such applications, outweigh the potential risks. The six project objectives were to: 1. Provide background information on the application of iron NPs in relation to soil and groundwater remediation; 2. To outline the benefits associated with the application of iron NPs in soil and groundwater remediation; 3. Identify the risks associated with using iron NPs for remediation; 4. Provide case studies demonstrating the use of iron NPs for remediation in other countries; 5. Provide recommendations on whether the benefits associated with the application of iron NPs for the remediation of contaminated sites, outweighs the potential risks; 6. Provide the key requirements that are necessary to evaluate the risks of using nanomaterials when exploited for remediation in order to permit their use.
