Groundwater. Water availability in Ukraine
According to United Nations data, in the early 2000s more than 1.2 billion people lived under conditions of constant freshwater scarcity, while about 2 billion experienced it regularly. According to the UN Report “Water and Sustainable Development of the World”, presented on March 20, 2015, in New Delhi (India), within the next 15 years the world’s population is expected to face a water deficit of at least 40%. One of the main reasons for this forecast is the depletion of groundwater reserves.
Despite the relatively large global reserves of freshwater on Earth, water scarcity is already increasingly felt almost everywhere in populated regions of the world. This is caused by several factors:
- uneven distribution of water resources across the Earth’s surface;
- rapid population growth worldwide and high concentration of people in certain regions, large cities, and urban agglomerations;
- increasing water consumption in agriculture and industry;
- pollution of water resources by wastewater and industrial waste.
What about Ukraine? To what extent are these problems relevant for our country? Obviously, a sharp increase in water demand due to economic growth or population growth is currently not a key issue for Ukraine. However, given the significant level of economic development of its territory, groundwater is an essential mineral resource of strategic importance, serving as a reliable and protected source of high-quality drinking water supply for the population. At present, the share of groundwater in Ukraine’s domestic drinking water supply is less than 25%. Ukraine also has significant potential to increase groundwater extraction, as only about 26% of its predicted groundwater resources have been explored.
Currently, around 700 deposits of drinking and technical groundwater have been identified in Ukraine. The total forecasted groundwater resources amount to 61,689.2 thousand m³/day, of which 57,499.9 thousand m³/day have mineralization up to 1500 mg/dm³. These resources are distributed unevenly across the country: the majority is concentrated in the northern and western regions, while southern regions have limited reserves. The largest forecasted groundwater resources are in the Chernihiv region (8,326.7 thousand m³/day), while the smallest are in the Kirovohrad region (404.6 thousand m³/day). The highest level of exploration of forecasted groundwater resources (over 50%) is observed in the central and southern regions of Ukraine.
The average annual extraction of drinking and technical groundwater in Ukraine is only about 5% of total forecasted resources and about 10% of explored exploitable reserves. In recent years, a steady decline in groundwater extraction has been observed.
It should be noted that while many explored deposits are not in use, some have already become unsuitable for exploitation due to disrupted recharge conditions caused by urban development; contamination of aquifers within reclamation systems, areas of filtration reservoirs, industrial waste dumps, and landfills; and extraction of gravel and pebble deposits from Carpathian rivers. Currently, hundreds of water intake systems in Ukraine operate on explored groundwater reserves, where water quality has deteriorated over time due to both natural and anthropogenic factors. The issue of providing high-quality drinking water is particularly acute in the southern and eastern regions of the country, as well as in mining and industrial areas (Odessa, Mykolaiv, Kherson, Zaporizhzhia regions, the temporarily occupied Autonomous Republic of Crimea, Donetsk Basin, Kryvyi Rih Basin, and the Carpathian region, etc.).
All of this creates the need for geological exploration of drinking groundwater and drilling artesian wells to ensure the population of Ukraine with environmentally safe drinking water. Considering Ukraine’s transition to a market economy and decentralization policy, financing of such works will mainly come from local budgets and private investors.
Increasing groundwater extraction for drinking water supply will support the implementation of national water policy principles, including aligning national drinking water standards with those of the European Union and maintaining an optimal balance between surface and groundwater use for water supply.
