Direct-push technology jet injection was used during full-scale treatment of a chlorinated solvent source zone at a site in Denmark, where 55 tons of micro-scale zero-valent iron blended with sand was injected into the clay till target treatment zone. The project included extensive post-injection assessment plus extensive membrane interface probe borings. Conventional soil sampling showed the total estimated chlorinated solvent mass in soil decreased by over 68% in 6 months and 82% in 30 months. Groundwater data collected from wells transecting the dissolved contaminant plume showed substantial reduction in chlorinated solvent mass flux out of the treatment zone, indicating that chlorinated solvent mass discharge from the source area declined by 89% after 30 months.
