Study of deep groundwater on the coastal area and its social role

Abstract

Geological Survey of Japan (GSJ) has carried out groundwater studies responding to social demands. Groundwater studies had been conducted for the development of resources and the protection of the environment in the past. These days, in addition, they are contributing to thermal energy use and practical use of the deep groundwater environment for high-level radioactive waste (HLW) and carbon dioxide capture and storage (CCS) projects. In this paper, we present the history of groundwater research at GSJ, current issues, and our approach to groundwater use.
