PROBLEM TO BE SOLVED: To provide a structure for purifying groundwater by a permeable reactive wall which prevents leakage of contaminated groundwater from columnar purification bodies.SOLUTION: In the structure for purifying groundwater by a permeable reactive wall which is provided with the permeable reactive wall 5 comprising the columnar purification bodies 4 juxtaposed in underground and impermeable walls 7 connected to the permeable reactive wall 5, grout 9 for preventing the leakage of the contaminated groundwater from between the columnar purification bodies 4 is formed between the columnar purification bodies 4. Preferably the grout 9 has non-leachability or low leachability of a reaction inhibitor of the permeable reactive wall 5. The grout 9 may be installed on the upstream side of the permeable reactive wall 5 or may be installed on both of the upstream and downstream sides thereof. |
