摘要： PURPOSE: To properly grasp a leakage state of polluted water through a partition wall throughout a wide range as diffusion of leaking polluted water is prevented from occurring. CONSTITUTION: A management method is provided in such a manner that polluted water 15 seeping from a charged material 11, such as waste and reclamation soil, charged in a region 20 surrounded with a cut-off wall 10 is prevented from leaking out of it through the defect spot of the cut-off wall 10 to the outside. The cut-off wall 10 is formed as double structure having a hollow part 18 nipped between the inner wall 16 and the outer wall 17. By managing water quality in such a way to sample residence water residing at a hollow part 18, the leakage state of polluted water 15 from the inner wall 16 is grasped. Further, water is poured in the hollow part 18 in such a manner that a water level is raised to a level higher than a water level in the region 20 surrounded with the cut-off wall 10 and by a head difference between the inside and the outside with the inner wall 16 nipped therebetween, leakage of the polluted water 15 from the inner wall 16 is prevented from occurring.
