Given the lack of technical solutions for global characterisation (2D or 3D) to detect and locate source zones of organic product contaminants, particularly organochlorines, in soils, the aim of this study was to identify and study innovative solutions. Two geophysical methods (spontaneous potential (SP) and induced polarisation (IP)) and a gas analysis method were tested on a pilot site, and have enabled us to increase our knowledge of the limits of the applicability of each method, as well as through the acquisition of new field data. However, it is still too ambitious to conclude whether the tools tested are suitable for detecting the pollutants we are looking for. The research subject remains completely open and further field studies will have to be carried out.
