This report compiles data set of the groundwater chemistry obtained at Mizunami Underground Research Laboratory (MIU) in the fiscal year 2008. These data include 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) is also described in terms of ensuring traceability of data.
