Geochemical properties of salinized groundwater at four areas(the east of Cheju Island, Korea, Chosei Village in Chiba Prefecture, Japan, and Tsuyazaki Town and Motooka is located the west of Fukuoka City in Fukuoka Prefecture, Japan) are studied. Consequently, it was found that geochemical properties of four salinized groundwaters have the different characteristics, respectively.
As regards tritium concentrat i ons, by comparing the tritium concentrations of the shallow groundwater alone with those of the deep one, the tritium concentrations of the shallow one showed higher concentrations than those of the deep one in Motooka. From
