Abstract

Radiocarbon activities and uranium isotopic disequilibria were measured in water samples from both the sandy Pleistocene coastal aquifer and within the upper Cretaceous Judea Group carbonate aquifer of northwestern Israel. The samples in both aquifers exhibit a decrease in ¹⁴C activity that is concomitant to the growth in ²³⁴U-excess. This suggests that under specific conditions, ²³⁴U-excess dating of groundwater can be used to corroborate ¹⁴C dates, while offering the possibility of extending the range of dating of groundwater beyond that of ¹⁴C.
