内容記述 | We propose a methodology for estimating the residence time of groundwater based on bomb-produced 36Cl. Water samples were collected from 28 springs and 2 flowing wells located around Mt. Fuji, Central Japan. 36Cl/Cl ratios in the water samples, determined by accelerator mass spectrometry (AMS), were between 43 × 10−15 and 412 × 10−15. A reference time series of the above-background (i.e., bomb-derived) 36Cl concentration was constructed by linearly scaling the background-corrected Dye-3 data according to the estimated total bomb-produced 36Cl fallout in the Mt. Fuji area. Assuming piston flow transport, estimates of residence time were obtained by comparing the measured bomb-derived 36Cl concentrations in spring water with the reference curve. The distribution of 36Cl-based residence times is basically consistent with that of tritium-based estimates calculated from data presented in previous studies, although the estimated residence times differ between the two tracers. This discrepancy may reflect chlorine recycling via vegetation or the relatively small change in fallout rate, approximately since 1975, which would give rise to large uncertainties in 36Cl-based estimates of recharge for the period, approximately since 1975. Given the estimated ages for groundwater from flowing wells, dating based on a 36Cl bomb pulse may be more reliable and sensitive for groundwater recharged before 1975, back as far as the mid-1950s. | |||||
