Greensoils first project in Switserland is located in St. Ursanne on a Cr6+ contaminated site. This project is started in Q4 by additional pre-remedial investigation in order to finetune the remedial concept based on excavation and/ or immobilization of Cr6+ to Cr3+ by in situ anaerobic bioremediation. Remedial works are planned to start in 2018.
