This report compiles data set of the groundwater chemistry obtained at Mizunami Underground Research Laboratory (MIU) between the fiscal year 2004 and the fiscal year 2007. These data includes groundwater chemistry of inflow in the shafts and sampled groundwater in the boreholes, which drilled from sub-stages of MIU and from surface (MSB-2, MSB-4, and MIZ-1). Basic information (e.g. sampling location, sampling date, sampling method, analytical method) are also described in terms of quality control and traceability.

Dynamic injection method increase the penetration of grout material and apply the grouting of small and low permeable crack in rock mass. This paper report the results of in-situ dynamic injection under high water pressure condition by using of the developed system reported Part1. This test used the borehole drilled in collaboration study between JAEA and AIST and the budget is a part of contract study from NISA.
