<p><P>PROBLEM TO BE SOLVED: To provide a method for sufficiently remediating polluted soil in an unsaturated band at a low cost in situ without eluting a polluting substance before its decomposition even in the case the polluted area is spread in a wide range and in the case the pollutant concentration is uneven. <P>SOLUTION: The method is for remediating polluted soil in situ by supplying water or an aqueous solution containing an activation agent for microorganism for decomposing a polluting substance to the surface layer of the soil polluted with the polluting substance in an unsaturated band, penetrating the soil with the water or the solution by spontaneous flow, and carrying out biological treatment of the polluted soil and is characterized in that the water amount in an arbitrary depth in the unsaturated band of the polluted soil is measured by a water analyzer and the water amount of the polluted soil is controlled. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
