Abstract

The variability is used to obtain information on the recharge and flow regimes in the aquifer waters. The method is based on repeated samplings of groundwaters on an evenly spaced time and space grid. The spread of isotope compositions is then compared with the scatter resulting from the analysis itself and with the variability of composition of the precipitation. The systems investigated were in the phreatic coastal aquifer of Israel and a limestone mountain aquifer, which is largely confined. In the coastal aquifer 130 wells in a 100 km**2 test area showed a bimodal distribution of the **1**8O isotope composition. In the mountain aquifer both the spatial and temporal variability was greatly in excess of analytical scatter.
