摘要

A method for preventing the contamination of subsoil water by harmful substances which originate from an object at or near ground level. A tunnel having a water permeable wall is formed below the natural water level to thus form a sink funnel in the subsoil. The accumulated water in the tunnel is drained away quickly enough so that the velocity of water movement toward the tunnel exceeds the water velocity in all other directions.
