One of the tasks in the program of the Mizunami Underground Research Laboratory is development of methodology for evaluating geochemical effects caused by construction of underground facilities. Using the M3 (Multivariate Mixing and Mass balance) analysis tool developed by SKB in Sweden, PHREEQC developed by USGS in USA, and the reactive chemical transport simulator (TOUGHREACT) developed by LBNL in USA, the analyses concerning hydrochemical changes of groundwater at the Mizunami Underground Research Laboratory was conducted to verify their modeling applicability and to construct a hydrochemical model for predicting perturbations caused by the shaft excavation in the next phase.

One of the tasks in the program of the MIU is development of methodology for evaluating geochemical effects caused by construction of underground facilities. M3 and TOUGHREACT analyses was conducted to verify their modelling applicability and to construct a geochemical model for predicting perturbations caused by the shaft excavation. The groundwater in the Tono area were classified four type. Many reactions suggested by the mixing calculation are in good agreement with earlier groundwater model.
