METHOD FOR PURIFYING CONTAMINATED SOIL/UNDERGROUND WATER AND STIRRING WELL FOR PURIFICATION

摘要

PROBLEM TO BE SOLVED: To provide a method for purifying contaminated soil/underground water and a stirring well for purification which can efficiently execute purifying treatment of the contaminated soil/underground water without drilling to the soil contaminated with volatile organic compounds accumulated in an upper part of a hardly permeable layer. SOLUTION: In the method for purifying the contaminated soil/underground water which executes original position purification of the contaminated soil/ underground water by installing wells at least in a saturated layer 2 and an unsaturated layer 1 among regions contaminated with the volatile organic compounds, an infiltration part 5 where contaminants stay is agitated by injection of high pressure water before execution of purification to diffuse the volatile organic compounds in the underground water 4 and thereby purification of the contaminated soil/underground water is efficiently treated.
