Ex-situ Treatment
Excavation of contaminated soils for treatment or disposal
For a large number of brownfield sites excavation of any contaminated soils is unavoidable to meet the constraints of the new development. Once excavated, contaminated soils historically were just sent for off site disposal to landfill employing the so called ‘dig and dump’ method. Whilst this remediation option still has a place, there are a whole suite of more modern and more sustainable remedial solutions available such as soils washing, bioremediation, thermal desorption and solidification. Consultants at BRD have direct working experience of many of these remediation techniques and so are well placed to advise on their applicability, pitfalls and advantages.
