The present paper defines the genetic components of the river Bodrak runoff in the region of the Second Crimean Mountains Range. Isotope composition of groundwater, surface water and precipitation (δ2?, δ18?) was investigated. Monitoring was carried out as a part of a student field training. Field practice was held on the Autonomous Republic of the Crimea, Ukraine (the village of Trudolyubovka, Bakhchisaray region). Isotope data (δ18O, δ2?) in groundwater, surface water and precipitation are presented in the paper. There were 12 water samples (from 2006 till 2011), such as: 6 samples of groundwater, 2 samples of surface water (river Bodrak) and 4 samples of precipitations (location coordinates - 44°47.10? N; 33°59.59? E, alt. 270 ?). The region is characterized by high rates of water exchange. The aquifer of fresh groundwater is the most widely developed. Groundwater aquifer is created by local precipitation. The recharge area that forms the flow of the river Bodrak is situated upper than the recharge area of the groundwater aquifer. Mainly, winter precipitation forms runoff of the river Bodrak. In summer, the water of the river Bodrak was slightly more enriched in 2H and 18O than in winter. Usually, river Bodrak is recharged with groundwater in summer. Isotope studies help to determine the origin of the groundwater and to provide with the information needed for sustainable groundwater management.
