Introduction to Frequently Asked Questions (FAQs) and Thematic Pages
In situ remediation technologies are now in use for managing risks from a range of soil and water contamination problems in several countries. The small particle size and high reactivity of nanoparticles may offer particular remediation benefits compared with existing in situ techniques. The best known and most frequently encountered is nano-scale zero valent iron (nZVI). The information for decision makers provided here focuses on nZVI, although it may also often be indicative for other nanoparticle types used in remediation.
nZVI has been deployed in the field at a substantial number of sites in several countries, in particular for the remediation of chlorinated solvent plumes. Laboratory and theoretical studies indicate that nanoremediation also has promise for offering treatment of a wide range of persistent contaminants such as PAHs, PCPs, PCBs and trace elements such as Cr (VI). nZVI may also offer the potential for faster and more complete remediation treatments.
Since the inception of nanoremediation as a technology more than ten years ago, a number of questions have been raised about it that decision makers may need to consider. In this NanoRem information area we provide a list of "frequently asked questions" (FAQs) to provide brief summary information, supported by pages of more detailed technical information organised in thematic topics. These pages are in constant review over the lifetime of the project, both to update their technical content and to extend their scope. Each page provides signposting to additional information, in particular the outputs of the NanoRem project as they become available in the NanoRem Publications Catalogue.
An important objective for NanoRem is to promote exchange between nanoremediation practitioners and decision makers and to allow them to provide feedback both on the project activities and nanoremediation more generally. These FAQs are intended to provide initial information to support nanoremediation project decision-makers, and also to begin this process of engagement. This information and exchange area will be further developed as the project progresses.
Currently we have the following FAQ pages:
The thematic pages are under development but will provide information on the following topics:
