Soil washing as with all other exsitu treatments is an excellent form of treatment...but be warned the technology has its limitations...!

It's best employed on granular soils with a low proportions of' fines' i.e. the cohesive soils particles such as silts and clays, on which the majority of contaminants adhere to.  

The washing process removes/reduces the contaminant concentrations on the granular materials by washing off the 'fines' and leaving a cleaned aggregate.  The lignates used in the 'wash waters' can vary from bio-solvents through to petrochemicals depending on the nature and type of contaminant to be treated. 

The 'fines' produced by the process are more often than not disposed of at a landfill site.

Soil washing generally requires a considerable amount of specialist plant and equipment and adequate space for stockpiles, drying areas and water treatment plant.
