PROBLEM TO BE SOLVED: To provide a method for arranging a cleaning agent in contaminated soil where a mixed cleaning agent of a cleaning agent and granular matter for percolation can be arranged at the deepest part of the dug part provided in contaminated soil without uneven mixing, and to provide a method for cleaning contaminated soil and/or ground water in situ.;SOLUTION: A hole 2 is formed as a dug part in a foundation 1. The hole 2 is dug so as to be deeper than the level of ground water. A mixed cleaning agent 6 such as iron powder mixed sand is fed to a bucket 4 by a power shovel 5. The bucket 4 is lowered to the deepest part of the hole 2. When the bucket 4 reaches the hole bottom 2a, a lock mechanism is made into a lock release state. Then, when the bucket 4 is gradually pulled up, a bottom cover 4a starts to be opened, and the mixed cleaning agent 6 in the bucket 4 is released from the bucket 4 to the bottom part of the hole 2. Further, the bucket 4 is pulled up, thus the whole of the mixed cleaning agent 6 is released.;COPYRIGHT: (C)2008,JPO&INPIT
