PROBLEM TO BE SOLVED: To provide a method for cleaning contaminated soil or contaminated groundwater in which the contaminated soil and the contaminated groundwater can be efficiently and readily cleaned by on-site handling when the soil and groundwater contained with much humus is contaminated by cyanogen and cyanides or when a plurality of contaminants, such as oil contents and volatile organic compounds, in addition to the cyanogen and cyanides, are intermingled in the soil and groundwater. SOLUTION: Iron powder or copper-containing iron powder is mixed with the soil and groundwater containing at least one of the humus, the volatile organic compounds and the oil component, and the cyanogen and thereby the cyanogen is immobilized.
