4. Soil: an open, multiphase, transient reactor
The presentation of physico-chemical treatment processes shows that they are based on classic process engineering unit operations: thermal treatments, inter-phase transfers, chemical reactions, etc. The major difficulty compared with conventional operations is that we are dealing with a natural anthropized environment, in all its complexity. The major difficulty in comparison with conventional operations is that, at the field scale, we are dealing with an anthropized natural environment, in all its complexity. In all cases, the treated soil can be considered as a multiphase reactor subject to the laws of thermodynamic equilibrium, chemical, biochemical and matter transfer kinetics, and heat transfer, all under given hydrodynamic and phase contact conditions

Standards and norms
Standards exist for sampling, sampling and analysis. No pollution control technique is currently covered by a standard. They cannot be standardized, as their application depends on numerous parameters linked to the site to be remediated.

Regulations
Existing regulations focus on the management of polluted soils, and are currently being revised. They address the following concerns: preventing and protecting the population from accidental or health-related risks associated with pollution. The DRIRE, which is responsible for managing and policing ICPEs, has a duty to the public to set clean-up targets.
