Ronse - full scale remediation of chlorinated solvents

Greensoil was ordered to conduct the full scale remediation of 3 hot spot areas of a cVOC impacted site in Ronse, Belgium. Remediation of soils in Area A and C has been completed by excavation.

Full scale groundwater remediation of of Area A and C is ongoing by enhanced anaerobic biodegradation. Area B is located inside a high technological 'clean room' building and therefore difficult to access. Additional preremedial investigation in Area B is conducted in preparation of a full scale remediation concept.

Meanwhile further off iste migration in Area B is being prevented by an anaerobic bioscreen.
