Rehabilitation techniques generally fall into four broad categories.
They include off-site, on-site and in-situ treatment techniques –, including physico-chemical, thermal and biological processes – and containment.
Among in situ treatment methods, there are technologies that can both control polluted underground flows and treat them in the very soil through which they pass.
These methods, commonly referred to as permeable reactive barriers (PRBs), are the subject of this dossier.

.
In the Techniques de l'Ingénieur collection, containment is the subject of the booklet
, which must be read to understand this text.
