Innovative analytical developments in the field of contaminated soils and sites. Contribution of the new measurement techniques for the rapid on-site characterization

Summary

In the field of polluted sites and soils (PSS), new trends are emerging in analysis methods. They are striving to obtain results quickly, efficiently and without the need for a fixed laboratory.

The aim of this study is therefore to take stock of innovative technical developments applicable in situ and on site in the field of SSP and to assess their potential. The use of these field techniques should make it possible to reduce the costs associated with SSP investigations, for example by limiting the number of samples to be taken.

After an overview of the technical developments described as innovative, 9 were selected for in-depth study, clearly explaining the technical principles of the method in question. Based on what suppliers and users have said, and on an in-depth literature search, the strengths and weaknesses of the systems are highlighted, as well as the opportunities opened up for the future.

As well as listing the technical solutions that could be used more widely in the future, several key points emerge from the study: the support of artificial intelligence, particularly for data post-processing, the potential complementarity between the various field technologies and standardised laboratory analyses, and the need to be aware of the limitations of each tool in order to master them properly.
