The anthropogenic load on the components of the natural environment in most regions has reached a level that threatens the population's health. The high pollution level of water sources is associated with excessive discharge of untreated and/or insufficiently treated wastewater from various sectors of the national economy. It directly or indirectly leads to a deterioration in sanitary and hygienic conditions and the spread of multiple diseases among the population.The purpose of the study is to establish the cause-and-effect relationship between the qualitative and quantitative state of the surface waters of the Samara River and certain classes of diseases of the population living in the territory of the Western Donbas region.Materials and methods of the study. The relationship between the qualitative and quantitative state of the surface waters of the Samara River and certain classes of diseases of the population was established using the method of statistical analysis based on the calculation of Pearson correlation coefficients with the determination of the confidence probability by comparing the calculated reliability criteria of the obtained correlation coefficients with the critical value of the Student t-criterion at different levels of significance. The study used statistical data from the State Statistics Service of Ukraine and the Ministry of Environmental Protection and Natural Resources of Ukraine for 2011-2022.Research results. With a high degree of probability, a direct relationship was proven between the increase in certain diseases of residents of the considered territory and the presence of pollutants in the studied reservoir. The following classes of diseases were most closely related to the qualitative and quantitative state of water: diseases of the blood and hematopoietic organs; diseases of the endocrine system; diseases of the circulatory system; diseases of the digestive system; diseases of the skin and subcutaneous tissue. Based on the results obtained, it will be possible to develop an operational system of environmental protection measures and measures to preserve the health of the population living in the surrounding areas.
