Large-scale on-site and in-situ bioremediation of xylene contaminated soil, soil vapor and groundwater

Greensoil conducts a full scale remediation at a heavily xylene impacted Seveso site in Westerlo, Belgium. Soil and groundwater show high concentration levels in two former production areas. The remediation is based on on site biopiling of the soil in the unsaturated and smearing zone and in situ aerobic bioremediation of soil and groundwater in the saturated zone.
