Zusammenfassung:PROBLEM TO BE SOLVED: To provide a solidification method of toxic substances preventing diffusion or vaporization of toxic substances (in particular, LNAPL) in underground water flow without being restricted by a place, with little cost. SOLUTION: In this solidification method of toxic substances, an injection rod is penetrated into an aquifer containing groundwater from the ground surface, and a solidifying material lighter than water is injected through the injection rod into the aquifer, to solidify the toxic substances present in an upper part of the aquifer.
