| Outline of Final Research Achievements |
The observation at northern coastal area in Fukushima have been carried out since 2012 to grasp the groundwater flow system. The water quality is mainly Ca-HCO3 type, however Na-HCO3 type, Na-Cl type and Ca-SO4 type are also existed. As a result of field survey and chemical analysis, it is considered that the multiple groundwater flow system which have the different residence time is existed. And it is assumed that the groundwater which was recharged around Abukuma Mountains shows the longer residence time. The residence time of groundwater is estimated about 10 to 30 years by using the tritium concentration. In future, the residence time of groundwater will estimate from a result of analysis of CFCs and SF6.
