UNDERGROUND CONTAMINATION RESTORATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide an underground contamination restoration method capable of efficiently performing in-situ restoration of an underground region contaminated with hazardous substances by utilizing the activity of microorganisms even when such underground region exists in the state as a calcium excess state. SOLUTION: The underground contamination restoration method of performing the in-situ restoration of the underground region contaminated with the hazardous substances by utilizing the activity of the microorganisms comprises compounding dihydrogen phosphate as a phosphorus component in a nutrient substance to be supplied to the contaminated subsurface region which is an object for restoration when the soil or ground water in the contaminated underground region exists in the calcium excess state.
