Based on the groundwater scenario, prediction of the transport of radionuclides from waste disposal facilities requires an understanding of deep groundwater flow system. Capabilities offering by isotope techniques using environmental tracer enable one to estimate past and present behavior of groundwater system, and therefore establish a basis for future predictions. A study area was selected in Japan and hydrogeological study has been performed. On the other hand, fractures in the hard rock mass play an important role on groundwater flow at the depth. Basic study was performed for resistivity tomography, one of the useful techniques for the evaluation of rock fractures.
