[AHW30-P04] Residence time of spring water on Mt. Haruna using multi-trancient tracer

*Kazuyoshi Asai1, Kazumi Asai1, Yasuo Shimano2, Yuji Kato1 (1.Geo Science Laboratory, 2.Bunsei University of Art)

Keywords:Mt. Haruna, tritium, CFCs, SF6, residence time

We carried out analyses of multi-trancient tracers on springs at Mt. Haruna. Based on the results, we determined the groundwater flow pattern and calculated the residence time.
