Mechelen - full scale remediation of chlorinated solvents contamination in soil and groundwater

Greensoil conducts a full scale remediation project of a chlorinated solvents impacted site in Mechelen, Belgium. The remediation is based on excavation of soil contamination and enhanced in situ bioremediation of soil and groundwater in saturated zone.

Groundwater remediation will be completed while the site becomes redeveloped. All system needed to be finished off at 2mbgl as boundary condition of the redevelopment.
