A system and process for in situ remediation of contaminated soils and/or residues is disclosed. These system and process take advantage of a radial flow irrigating/draining system and a multi- level sensor arrangement located at midspacing between parallel, horizontal conduit lines to create an environment propitious to the action of decontaminating agents (plants, microorganisms, salts, acids, bases, buffers, enzymes, substrates, surfactants, etc.). For example, a water-saturated zone is created and the level of water containing decontaminating agents is raised, maintained and/or lowered; the water-saturated zone encourages desorption or solubilization of soluble contaminants through adjustment and control of at least some parameters of reaction (time, temperature, pH, oxygenation, etc.) The system and process are easily adaptable for many classes of contaminants, including volatile compounds and light non-aqueous phase liquids, by further installing supplementary sets of conduit lines and pumps at adequate levels. Remediation of a site may be conducted by alternating gaseous and liquid modes to optimize the conditions of reaction.

L'invention concerne un procédé permettant de restaurer des sols contaminés et/ou de traiter des résidus. Ce procédé fait appel à un système d'irrigation/drainage horizontal et radial, avec des détecteurs (8) disposés à mi-distance entre des conduites parallèles (5), pour créer un environnement propice à l'action d'agents de décontamination (plantes, micro-organismes, sels, acides, bases, tampons, enzymes, substrats, tensioactifs, etc.). Par exemple, on peut créer une zone saturée en eau, on peut monter, maintenir et/ou descendre le niveau de l'eau contenant les agents de décontamination pour améliorer la désorption ou la solubilisation de contaminants solubles et on peut optimiser les paramètres de réaction (durée, température, pH, oxygénation, etc.). Le procédé peut facilement être adapté à différents types de contaminants, en particulier aux composés volatils, aux liquides non aqueux légers en installant d'autres conduites et moyens de pompage aux niveaux appropriés. On peut traiter le site en alternant le traitement par l'air et par l'eau pour optimiser les conditions de réaction, ce traitement alterné étant mis en oeuvre d'une manière avantageuse dans un système à plusieurs unités, une unité étant en mode gazeux pendant que l'autre unité fonctionne en mode aqueux.
