The relevance of this study is determined by the need to assess the risks of pollution of surface and groundwater in the Northwestern Black Sea region under the conditions of climate change and military aggression against Ukraine by Russia.
The main factors contributing to the pollution of surface and groundwater include discharges from stationary and diffuse sources. The former consists of point-source discharges of municipal wastewater, while the latter includes the distributed inflow of pollutants from the catchment surface. Prior to the outbreak of hostilities, diffuse pollution was primarily associated with the runoff of nitrogen compounds from agricultural lands. The EU Nitrates Directive specifically aims to protect water from pollution by ammonia, nitrites, and nitrates. However, with the onset of military actions in the Northwestern Black Sea region, new industrial pollutants have emerged due to the destruction of energy, railway, and port infrastructure, damage to bridges and overpasses, and the release of hazardous substances from military debris (missiles, drones, etc.). The impact of chemical pollutants of various origins is further aggravated by the reduction in river inflows as a result of climate changes. It has been established that modern warming trends lead to the depletion of local water resources, a decrease in the inflow of freshwater to the estuaries of the Northwestern Black Sea, and their gradual shallowing and salinization. The Odesa region plays a key role in supplying the country with agricultural products under the conditions of military operations, as the agricultural lands of the Mykolaiv and Kherson regions have suffered significant damage due to the hostilities. The importance of irrigation is increasing, along with the need for the restoration and modernization of irrigation systems.
