Use of isotopes in examining precipitation patterns in north-central Ukraine.

North-central Ukraine is vulnerable to temperature increases and precipitation pattern changes associated with climate change. With water management becoming increasingly important, information on current water sources and moisture recycling is critically needed. Isotope ratios of oxygen (O) and hydrogen (H) in precipitation are sensitive to these variables and allow comparisons across the region.

Variation of tap-water isotope ratios and municipal water sources across Kyiv city, Ukraine.

Unlabelled: Stable isotopes of water allow researchers to examine water pathways and better understand spatial and temporal variability in mixtures of municipal water sources. In regions such as Kyiv (Ukraine), with a water supply that is vulnerable to the effects of climate change, pollution, and geopolitical conflict, such understanding is critical for effective water management. Trends in stable isotope values and water sources can function as a confirmation of municipal data.
