Iwatsuki, Teruki  ; Mizuno, Takashi   ; Amano, Yuki   ; Kunimaru, Takanori; Semba, Takeshi 

This report summarizes technical basis and the Know-how on hydrochemical investigations for deep underground as a part of METI project "Development of Information Synthesis and Interpretation System (ISIS)". We describe the procedures and methods of hydrochemical investigation in following stages; (1) initial analysis of previous information, (2) planning of borehole investigation, (3) borehole investigation at field, and (4) construct the "hydrochemical model" representing hydrochemical condition and the evolution process. The contents of this report are inputted to "Expert system" developed by METI project and are available via WEB system (internet).
