Following the decision made by the consortium during the project meeting in Barcelona, 20-21 September 2017, an additional pilot-test was performed in an industrial park close to Cologne, Germany. The aquifer is contaminated with Zinc.

At June 5th, 2018 ca. 40 cubic meters of optimize NPs were injected into two wells in order to install a ca. 9 m wide barrier. The injection was concluded successfully, and the early results show almost complete removal of Zinc concentrations of initial 12mg/L. The monitoring will continue until Dec. 2018.
