内容記述 | We determined the chemical compositions and tritium concentration of precipitations sampled from the rooftop of our institute building and the groundwater collected from four wells in the Niigata University campus and irrigation wells in the dune area in west Niigata city. The precipitations were classified into two types on the basis of chemical compositions: the low electrolyte type collected in the “baiu” season and the high electrolyte type sampled in the snow fall season. The high electrolyte water was rich in sea salt and sulfate ion. The sea salt must be carried from the Japan sea by strong NNW winds. The exess sulfate ions carried by the winter-monsoon are concluded to be of continental origin taking into account the direction of winds and the geographical situation of Niigata city. The sulfate and nitrate ions concentration of the irrigation water were higher than the expected values from the chloride ion concentrations of precipitation samples. These anions must be condensed by the percolation process caused by irrigation in farmlands. The mean tritium concentration of precipitations was 27.7 pCi/1 (1987). The groundwater from observation wells in Niigata University can be separated into two layers, the upper layer having low T and low electrolyte concentrations and the lower layer having high T and high electrolyte concentrations. Many groundwater samples showed a low T-concentration corresponding to that of recent precipitation but some samples had a higher T-concentration than 40 pCi/1 and three samples contained quite low tritium (less than 20 pCi/1). A model of the groundwater having more than two layers is necessary to explain the behavior of the chemical composition and T-concentration of groundwaters in the dune. | |||||
