The present invention provides a supported catalyst for in situ remediation of soil and/or groundwater contaminated with a halogenated hydrocarbon comprising an adsorbent impregnated with zero valent iron, wherein the adsorbent is capable of adsorbing the halogenated hydrocarbon. This invention further provides a bioremediation composition for in situ bioremediation of soil and/or groundwater contaminated with hydrocarbons, comprising an adsorbent capable of adsorbing said hydrocarbons, a mixture of facultative anaerobes capable of metabolizing said hydrocarbons under sulfate-reduction conditions, a sulfate-containing compound that releases sulfate over a period of time, and a nutrient system for promoting growth of said anaerobes, wherein said nutrient system includes a sulfide scavenging agent.
L'invention concerne un catalyseur supporté destiné à un assainissement du sol et/ou de la nappe souterraine contaminée aux hydrocarbures halogénés comprenant un absorbant imprégné d'un fer à valence zéro, cet absorbant étant capable d'absorber l'hydrocarbure halogéné. L'invention concerne également une composition de biorestauration destinée à la biorestauration <i>in situ</i> du sol et/ou de la nappe souterraine contaminée aux hydrocarbures, comprenant un absorbant capable d'absorber ces hydrocarbures, un mélange d'anaérobies facultatif capable de métaboliser ces hydrocarbures dans des conditions de réduction de sulfate, un composé contenant du sulfate libérant le sulfate sur une période de temps, et un système d'élément nutritif destiné à favoriser la croissance de ces anaérobies, ce système comprenant un agent de piégeage de sulfure.
