CLEANING METHOD FOR CONTAMINATED SOIL

摘要

PROBLEM TO BE SOLVED: To provide a cleaning method for contaminated soil capable of confirming spreading in a depth direction of a nutrient poured to the contaminated soil and sufficiently cleaning the contaminated soil without obstructing a dechlorination reaction of an organic chlorine compound. SOLUTION: In the cleaning method for the contaminated soil G', the nutrient A for activating a microorganism is poured into the contaminated soil G' contaminated by the organic chlorine compound and the contaminated soil G' is subjected to biological treatment to clean it. A phosphoric acid salt is added to the nutrient A poured to the contaminated soil G' and an electric resistivity of ground water at a predetermined depth position in the contaminated soil G' is measured.
