PROBLEM TO BE SOLVED: To provide a purifying method of a polluted ground in which contaminants in a stock solution state which exist in soil shallower than a grand water level and water in the polluted gap of the periphery are efficiently sucked in and removed, and the shortening of a processing time and the reduction of a treatment cost are aimed at, and to provide a purifying body. SOLUTION: The method is composed of a purifying body arranging process, in which a subterranean freezing pipe and a subterranean suction body are arranged in a proper pitch in the polluted ground with contaminants existing in the soil shallower than the grand water level, of a freezing process freezing the polluted ground region, and of a stock solution suction process, in which the contaminant in a liquid form is sucked in from the subterranean suction body in a state where the freezing condition is maintained.
