Karst springs in the Main Range of the Crimean Mountains and the Crimean Piedmont show a restricted range of values (δ<sup>18</sup>O = -10.5 to -8.0 ‰, δ<sup>2</sup>H = -72 to -58 ‰), somewhat more negative than the weighted mean of meteoric precipitation. This suggests preferential recharge at higher elevations during winter months. Groundwater tapped by boreholes splits in three groups. A first group has isotopic properties similar to those of the springs. The second group shows significantly
