Study for artificial recharge process of groundwater using natural isotope tracers

For overcome groundwater shortage at winter greenhouse farming, artificial groundwater recharge system was developed. And recharge process was studied by using natural isotopes, such as 3H, 222Rn and 87Sr/86Sr ratio variation. The 222Rn concentration variation was from 0.9 to 85.1 Bq/L depending upon the well. The concentration of 222Rn was decreased when water curtain cultivation and artificial groundwater recharge were started and slowly increased after these processes were ended. The 87Sr/86Sr ratio variation of the three monitoring well showed different appearance.
