COLLECTING METHOD FOR SOIL PORE WATER AND INVESTIGATION METHOD FOR SOIL CONTAMINATION

摘要

PROBLEM TO BE SOLVED: To provide a method to simply and inexpensively grasp a potential of underground water contamination and a contaminating source of underground water, and to accurately investigate a soil contamination distribution. ;SOLUTION: A shallower hole H than an underground water level is bored in the ground G. Slurry S₁ of particulate solid is flown into the bottom of the hole H, and a permeable part 2 at an lower part of a sampler 1 is buried in this slurry S₁. Slurry S₂ is then flown onto the slurry S₁ to seal the hole. Moisture in the slurry is suctioned into the sampler 1 by a vacuum pump 11, and is then suctioned up to a container 8 to throw away. Soil pore water is then sucked into the sampler 1 by depressurizing the inside of the sampler 1, and is sucked up to the container 8 to collect and analyze.;COPYRIGHT: (C)1999,JPO
