The anthropogenic load on natural environment has reached a level that threatens the population health. The main causes of water sources pollution are the discharge of untreated or insufficiently treated wastewaters by industrial enterprises. These and other reasons lead to the spread of various types of diseases among the population. A cause-and-effect relationship between the qualitative and quantitative state of the surface waters of the Samara River and certain diseases of the population living in the Western Donbas region has been established. The method of statistical analysis based on Pearson correlation has been applied. Reliable correlation between the pollutants content in surface waters of Samara River and the increase of the population diseases in the investigated territory has been proven. With high degree of probability, the following diseases are closely related to water quality: diseases of the blood, hematopoietic organs and disorders of immune system; diseases of endocrine system, digestive and metabolic disorders; circulatory system and digestion diseases; diseases of the skin and subcutaneous tissues. The obtained results indicate the need for further research taking into consideration the regional specificity of conditions and factors of environmental pollution, development of advanced water treatment to reduce the morbidity rate of the population.

“…Tendencies in changing the quality of water resources [12,13], their eff ective management, protection and restoration [14] are studied. The issue of the negative consequences of regulating the water fl ow of small and medium-sized rivers is becoming more relevant, it indicates the need and practical implementation of disassembling dams and spillovers [15], restoring the water fl ow and ecosystems of small rivers [16,17]. In Ukraine, a large network of hydrometric posts was created to study the hydrological regime and quality of water resources [11,18].…”

Purpose. Study the spatial distribution of artificial reservoirs in the Dnipropetrovsk region and fragmentation impact of small riverbeds on changes in the quality of water resources. Methodology. Field studies on the current state of small river basins were carried out, rivers were selected on the principle of different geographical location and levels of anthropogenic impact. Analytical laboratory studies of water salt composition and methods of mathematical analysis were used to establish the dependence coefficients of water mineralization level and fragmentation of the river basin on the water flow regulation. Findings. The structure of the spatial distribution of artificial reservoirs in the administrative districts of the region and their hydrological characteristics are generalized. It is shown that small volumes of accumulated water in relation to the total area of reservoirs are the cause of intensive heating and evaporation of water. Due to this, the hydrochemical parameters of water are worsen, which affects the environmentally safe water use. It was found that the level of mineralization, the content of sulphates and chlorides exceed the maximum acceptable concentrations in all studied rivers. There is a tendency of deterioration of water quality in the salt block, especially in rivers with significant regulation of artificial reservoirs. In this case, water salinity exceeds the norm by 712 times. Indicators of water mineralization of rivers with fewer ponds and less fragmentation of the river basin exceed the standards by 25 times. Originality. It is determined that among the main factors of anthropogenic impact on the state of aquatic ecosystems is the fragmentation of riverbeds by artificial reservoirs, which turned rivers into cascades of water evaporating ponds. There is a close relationship between the factors of water flow regulation and the level of water mineralization (coefficient of determination R2 =0.62), as well as the coefficient of fragmentation of the river basin (R2 = 0.61). This proves the possibility, in the conditions of research of small rivers, to estimate the degree of change (increase) of water mineralization level by the coefficient of water flow regulation Kw and the coefficient of river fragmentation by the area Practical value. The main directions and ways to normalize the ecological status of watercourses are given. The necessity of systematic study of the current ecological condition of small rivers of Dnipropetrovsk region and their basins is determined.

Formulation of the problem. For the last 30 years, water management in the basins of small rivers in the steppe zone of Ukraine has led to a deterioration of the environmental safety in water use. The current ecological state of small rivers is close to critical, and for today some river basins are subject to catastrophic environmental changes. Almost all small rivers from 70 to 100% in the south and central water-short regions of Ukraine are under regulation due to the construction of a large number of ponds and reservoirs. In most cases, this causes a lack of transportation and low self-cleaning ability. Thus, the conservation, restoration and rational use of water, based on the principles of basin management, should get started along with the improvement of the ecosystems of small rivers.Research results. The paper describes the dynamics of changes in water management, which shows a rapid increase in the number of new ponds in the period of 1990 - 2018 almost threefold. At the same time, the overall dynamics of water consumption in the region in the same period decreased fourfold. Unjustified imbalance between the construction of new facilities and water demand was determined, as well as non-compliance with the current statutory provisions. Due to the transformation of natural watercourses into cascades of "evaporator ponds" an ecologically dangerous transformation of small river basins with the change of hydrological, hydrochemical, hydrobiological and sanitary regimes takes place. To evaluate the level of environmental hazards associated with water management, it is proposed to determine the river fragmentation coefficient, which is the ratio of the number of ponds and reservoirs to the length of the river. When evaluating the environmental hazard for rivers in a specific territory (administrative area, district or catchment area), the fragmentation coefficient is determined by the ratio of the number of ponds and reservoirs to the size of the territory. Comparative analysis indicates that Dnipropetrovsk region is one of the most environmentally dangerous in terms of the negative impact of river basins fragmentation by artificial reservoirs. The case of a small river basin (the Nyzhnia Tersa River) presents the application of the approach to evaluate the level of environmental safety associated with water management. It is proposed a mechanism for increasing the level of environmental safety in water use by observing and implementing heterogeneous groups of indicators that determine the overall efficiency of the river ecosystem functioning.Conclusions. In order to stabilize and restore the hydrological and ecological state of small rivers in the steppe zone of Ukraine, it is important to: 1) make a detailed evaluation of the compliance of the available number of ponds and small reservoirs in river basins with the requirements of the Water Code of Ukraine; 2) prove ecologically and economically the feasibility of further operation for each individual reservoir and structure; 3) develop regional programs for the elimination of ponds and reservoirs that do not fulfil their water management functions and cause environmental hazards to the functioning of the river basin ecosystem; 4) improve methodological approaches to evaluation of the environmental safety of water facilities in small river basins.
