GROUND WATER QUALITY MEASUREMENT METHOD AND GROUND WATER QUALITY MEASUREMENT DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a ground water quality measurement method and a ground water quality measurement device capable of correctly measuring water quality of ground water at an original position.;SOLUTION: Volume of a sampler bottle 26 immediately before ground water is collected and sealed is set to become zero, and ground water at an original position is collected and sealed in the sampler bottle 26, then the sampler bottle 26 collected on the ground is placed in a glove box 44 having air tightness and into which a hand can be inserted from outside for glove fitting operation. Then, a pH meter 46 and an ORP meter 48 are placed in the glove box 44, then inert gas (nitrogen) is filled in the glove box 44. Then, an oxidation state in the glove box 44 is detected by an oxygen analyzer, and after confirmation that inside of the glove box 44 is in a reduction state, the sampler bottle 26 is opened for measuring the pH and the ORP in the ground water.;COPYRIGHT: (C)2015,JPO&INPIT
