Abstract
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. Additionally, these data can provide an early signal for the effects of climate change on these sources, reducing uncertainty from physical measurements. For this study, tap water, surface water, and groundwater were collected over 14 months in Kyiv and nearby Boryspil, Brovary, and Boyarka and measured for hydrogen (δ2H) and oxygen (δ18O) stable isotopes. The stable isotope values from the tap water for each district show a general seasonal trend in water sources, with more groundwater used in the supply in the winter for most districts. Spatially, groundwater use increases from south to north in the left-bank districts in Kyiv city and groundwater use generally decreases from south to north in the right-bank districts. As precipitation patterns shift and temperatures increase, the reliance on particular water sources may need to shift as well. Overall, δ2H and δ18O data provide a baseline expectancy for current water use throughout the year and, from this, deviations can be assessed early.

期刊介绍:
Discover Water is part of the Discover journal series committed to providing a streamlined submission process, rapid review and publication, and a high level of author service at every stage. It is an open access, community-focussed journal publishing research from across all fields relevant to water research.
Discover Water is a broad, open access journal publishing research from across all fields relevant to the science and technology of water research and management. Discover Water covers not only research on water as a resource, for example for drinking, agriculture and sanitation, but also the impact of society on water, such as the effect of human activities on water availability and pollution. As such it looks at the overall role of water at a global level, including physical, chemical, biological, and ecological processes, and social, policy, and public health implications. It is also intended that articles published in Discover Water may help to support and accelerate United Nations Sustainable Development Goal 6: ‘Clean water and sanitation’.
