Process for Removing a Contaminant From Contaminated Groundwater

摘要

The invention relates to a process for removing a contaminant from groundwater wherein it is not necessary for groundwater to be extracted from the soil. To that end, the process according to the invention comprises the following steps: a) a biologically active layer ( 2 ) is applied on or in the soil b) the contaminated groundwater is contacted with the biologically active layer ( 2 ). The contaminant is converted in the biologically active layer. The biologically active layer ( 2 ) may be applied discontinuously. The contaminated groundwater may be contacted with the biologically active layer with the aid of for example a gas.
