PURPOSE: To efficiently repair polluted soil by bacteria. 8W CONSTITUTION: This method for repairing soil polluted with a contaminant by introducing at least one of bacteria decomposing the contaminant, a nutritive substance for bacteria decomposing the contaminant and an inducing substance developing the decomposition capacity of bacteria decomposing the contaminant into the polluted soil has a process controlling the coefficient of water permeation of soil so as to uniformly distribute the substance introduced into polluted soil throughout the soil region to be repaired. Further, a soil treatment method has a process preparing the soil region to be repaired having the soil polluted with the contaminant so that the distribution of the coefficient of water permeability has a plurality of the max. values and a process controlling the coefficient of water permeability of the soil so that the max. value having the substantially min. coefficient of water permeability shows the max. ratio. |
