The full-scale invasion by the russian federation has significantly impacted the quantity and quality of water in the rivers located within the conflict zone. The explosion at the Kakhovka HPP was accompanied by the most catastrophic consequences for hydrological systems. Due to ongoing active military operations in the region of the disaster, direct measurements of water flow there are impossible. Therefore, in this study, the average year discharge of the Dnipro River for the year 2023 was calculated using computational methods. Therefore, the paper separately examined the flow of the Dnipro River for flow without Kakhovka HPP Explosion; and the actual flow in 2023. The lag time of the flow in the section between the Dnipro HPP and the Kakhovka HPP was determined through joint daily observations of water discharge in 1952 at the Dnipro HPP and Beryslav stations. Changes in the inside-year distribution of runoff were determined by comparing the actual average monthly water discharges of the Dnipro HPP with the normalized monthly discharge values of the Kakhovka HPP for the year 2023. An automated method for decoding satellite images was also used in the study to create a map showing the main stages of the desiccation of the former Kakhovka reservoir bed. Using automated satellite image interpretation, we created a map showing the main stages of dewatering of the bed of the former Kakhovka Reservoir. The difference between our calculated real flow in 2023 and the flow brought to conditions without dam blowing is water, that the Kakhovka Reservoir failed to retain could have been used for industrial and agricultural production, water supply and sewage, the normal functioning of nature reserves, tourism, water transport, and much more. All of these losses are very difficult to assess, but they definitely need to be recorded.

The paper describes the purposes of the Kakhovka reservoir, which was the final in a series of large reservoirs created out of the Dnipro River in Ukraine. Importantly the paper presents the water consumption balances of the reservoir prior to its destruction on June 6, 2023. This consumption is divided up by economic sector – energy, agriculture, fishing, industry, transport, and household use and also with details on inter- and intra-annual water demand trends and variations (prior to destruction). The water needed to maintain important ecosystems in the reservoir and south of the now destroyed dam is also accounted for. This overview of water consumption is then used as input in an analysis of how prospective water-uses of the Dnipro River, including water needed to maintain important ecosystems, can be met given the situation now where the Dnipro River still exists, but the reservoir and dam, which were important for regulating and maintaining flow-rates and water-levels at different times of the year, do not exist at the moment.

Drinking water quality requirements regulate the maximum permissible concentrations of various contaminants to ensure public safety. Methods for testing the quality of drinking water and the frequency of their implementation are determined by the legislative standards governing the activities of water supply companies. The main hygienic requirements for drinking water quality include epidemic and radiation safety, positive organoleptic properties and non-toxic chemical components. In times of military aggression and conflict, there is a serious threat of water pollution. Military operations can lead to damage and destruction of water infrastructure, such as water supply systems, water treatment plants and other facilities. This may result in the penetration of contaminants, including bacteria, chemicals and other harmful substances, into drinking water sources. Such water contamination can pose a serious risk to public health through the possible spread of disease, transmission of infections and other water-related illnesses. Most chemicals pose problems only when exposed over a long period of time; however, some harmful chemicals that enter drinking water are of concern due to their effects over a short period of time. A system of monitoring and early detection of threats is an important element for effective response to potential water contamination under martial law. This system should continuously monitor the quality of water at all stages of its processing, from its entry into the water supply system to its distribution. Any anomalies or changes in water quality may indicate potential contamination, and the monitoring system should alert the relevant services and authorities to take the necessary measures. Identifying potential chemical, biological, radiation and nuclear water contaminants for priority control is critical for the organization and reliable functioning of the monitoring system and early detection of threats in wartime. The task of improving and upgrading drinking water supply systems that pose the greatest risk to public health should be considered a priority. Once potential threats are identified, the monitoring system can respond in a timely manner, preventing contamination of drinking water and ensuring the safety of water supply systems. Keywords: drinking water, chemical, biological, radiation and nuclear pollution, monitoring, safety plan.
