DRINKING WATER QUALITY AND IMPROVEMENT OF WATER PREPARATION TECHNOLOGY IN THE SAMARIV DISTRICT OF THE DNIPROPETROV REGION

To investigate the drinking water parameters based on sanitary-chemical and epidemiological indicators in ac-cordance with DSANPiN 2.2.4-171-10, with the aim of achieving satisfactory conditions and implementing the 6th United Nations Sustainable Development Goal, “Clean Water and Sanitation.” Water samples were collected in accordance with the Resolution of the Cabinet of Ministers of Ukraine dated October 4, 2022, No. 1114, “On the Approval of the Procedure for Sampling and Testing Samples for Services of Centralized Water Supply, Hot Water Supply, and the Supply and Distribution of Natural Gas.” The water samples were analyzed in laboratories using standardized measurement methods that are mandatory for use in the field of legislatively regulated metrology during the monitoring of the state of the natural environment (water). The primary pollutants in the drinking water of the Samaryivskyi district of the Dnipropetrovsk region were analyzed. An elevated level of permanganate oxidizability and ammonium was detected, which characterizes chemical pollution resulting from industrial emissions and the intensive use of plant protection products and mineral fertilizers in agriculture. All samples exhibited a significant exceedance of total hardness, even relative to the DSANPiN indi-cators, which have been relaxed under martial law conditions. The examined water can be utilized for drinking water supply after reducing its mineral components and overall hardness. In the villages of Spaske, Dmytrivka, and Khuto-rohubynyha, there exists a significant threat to public health due to the presence of considerable total microbial contamination in the drinking water. For the first time, the quality of drinking water in the Samaryivskyi district of the Dnipropetrovsk region has been examined, taking into account the current state of the district’s drinking water supply. The study analyzed po-tential specific sources of pollution (industry, agriculture) in the district and provided recommendations for the use of modern mobile water treatment stations. The analysis of drinking water quality for the community provides a basis for the justified requirement to install modern purification systems utilizing the proposed EcoSoft system. As a result, the drinking water in the settlements will comply with the requirements of DSANPiN 2.2.4-171-10, thereby reducing the risk of diseases among the popu-lation and mitigating negative impacts on ecosystems.
