REGROUND consortium, in collaboration with Research Institute of Applied Science (RIAS) in Iran, are testing the proposed technology in a site, where the contamination has a geogenic source. A site has been selected near the city of Takab. RIAS has prepared the site for application, including drilling new wells and sampling existing wells and springs. University of Duisburg-Essen (the coordinator, and on behalf of the consortium) provides the nanoparticles and supervises the application. The injection is planned at the end of March 2018.
