Short summary

The direct impact of rainfall on groundwater at Mt. Fuji, the largest volcanic mountain in Japan, was elucidated by multiple analyses including microbial DNA. Bacterial abundance and DNA not only supported the findings on the movement of groundwater obtained from chemical analyses but also elucidated chemically unseen flow. Evidence of piston flow in deep groundwater was first shown through changes in archaeal density and diversity. Microbial analysis extends our understanding of groundwater.
