Purpose – perform an ecological assessment of the quality of the rivers of Zhytomyr region (within the pool of the Pripyat river). Method. The study was conducted according to systematic observations based on the ecological classification of the quality of surface water and estuates in Ukraine, which includes a set of hydrophysical, hydrochemical, hydrobiological and other indicators reflecting the peculiarities of components of aqueous ecosystems. On the basis of common environmental criteria, the methodology makes it possible to compare the quality of water at different sites of water bodies, in water bodies of different regions. The calculation of the ecological assessment of water quality was carried out within three blocks: block of salt composition (І1), block of trophic-saprobiological (ecological-sanitary) indicators (І2) and block of indicators of content of specific substances of toxic action (І3). The results are presented in the form of a combined environmental assessment based on the final conclusions of the three blocks and based on the calculation of the integrated environmental index (IE). Results. An analysis of the modern ecological state of the rivers of the Zhytomyr region was carried out (within the Pripyat River Basin) and an assessment of the quality of their water according to the relevant categories. The results of observations on the qualitative state of surface water of the rivers of the rivers, uz, yarn, norin (within the Zhytomyr region) indicate their satisfactory condition. Water rivers, uz, norin correspond to the III class of water quality ("satisfactory" by class, "weakly polluted" by degree of purity). The best quality of surface water is observed in the river the river (II quality class, "good" by class, "fairly clean" by degree of purity). The greatest influence on the formation of water quality in rivers studied have indicators of a trophy-saprobiological block. This is due to a high anthropogenic load in river basins, in the first place discharges of insufficient sewage. Scientific novelty. For the first time on the basis of analytical studies and stock materials, an ecological evaluation of the surface water of the rivers of the rivers, shoving, UZ, Norin within the Zhytomyr region in three blocks of indicators: saline composition, trophoprobiological parameters and specific substances of toxic action. The integral ecological index is determined. The tendencies of accumulation of pollutants in the surface waters of rivers studied are established. Practical significance. The studies have allowed to analyze and evaluate the environmental state of the rivers of the rivers of the Zhytomyr region within the pool of the Pripyat River, which will establish the environmental standards of water quality and to determine the basic directions to improve the state of water resources and substantiate the system of recommendations aimed at improving the environmental status of the studied. pools within the area.

Aim. The purpose of this study is to develop a methodology that takes into account the levels of anthropogenic transformation of various components of the environment.Method. In scientific work to take into account the impact of qualitative indicators on the process of transformation of landscapes of Volyn region under the influence of drainage reclamation was used P. Shishchenko's method with the following additions: the coefficient of anthropogenic transformation of landscapes was calculated separately for: relief and soils and water regime.Results. Understanding the state of lands transformed in the process of drainage reclamation provides an opportunity to understand the effects of a complex of factors on land and agricultural needs and encourages scientific study of various components of the environment. During drainage reclamation there is an intensive mineralization of the organic part of the soil with a significant increase in greenhouse gas emissions and the processes of peat mineralization are actively developing. The total coefficient of anthropogenic transformation of landscapes was defined as the average value between these coefficients. The results obtained by an improved method allow a more differentiated assessment of the state of transformation of the landscapes of the Volyn region, taking into account the impact of drainage reclamation. These results are adequate, as there is a connection with the industrial development of territories and the level of agricultural development.The scientific novelty lies in the constructive-geographical analysis of the impact of drainage reclamation in the Volyn region on different types of environment.Practical significance. The results of the research can be used in the educational process of VSU named after Lesya Ukrainka and other educational institutions in teaching geographical, economic and tourism disciplines. The results will find their application in the legislative and executive work of local governments in the development of programs of socio-economic development of territorial communities. The materials of the research will promote the rational use of anthropogenic resources and objects of social and household services in Volyn, which will allow to qualitatively influence the course of administrative reform. A number of provisions can be used in similar studies of the regions of Ukraine.

Method. Environmental assessment of the surface water of the Guyva River was carried out using the system of classification of standards for the assessment of surface water quality of Ukraine. On the basis of common environmental criteria, the methodology makes it possible to compare the quality of water at different sites of water bodies, in water bodies of different regions. The calculation of the ecological assessment of water quality was carried out within three blocks: block of salt composition (І1), block of trophic-saprobiological (ecological-sanitary) indicators (І2) and block of indicators of content of specific substances of toxic action (І3). The results are presented in the form of a combined environmental assessment based on the final conclusions of the three blocks and based on the calculation of the integrated environmental index (IE). Results. omprehensive studies on changing the water quality of the Guyva River were conducted within the Zhytomyr region during 2016-2017. The water quality of the river according to the final values of the integral indicators of water quality of the three blocks varies within the II and III quality classes. The total environmental indices (IEs) for the mean and worst indices are 2,9 and 3,1 respectively. In general, the water quality along the main channel of the Guyva River within the Zhytomyr region corresponds to the second class, 3 categories, 3(2) subcategories according to the average quality indicators (in the state of "good" with a slope to "very good", in terms of purity bias to "clean") and 3 subcategories by worst performance (good for good, clean enough). The total values of the integral surface water quality indicators of the Guyva River indicate their contamination by trophic-saprobiological components. Scientific novelty. For the first time, on the basis of analytical studies and stock materials, an ecological assessment of the surface waters of the Guyva River within the Zhytomyr region was carried out by three blocks of indicators: salt composition, trophic-saprobiological indicators and specific toxic substances. The integral ecological index is determined. The trends of pollutants accumulation in the surface waters of the River Guyva have been established. Practical significance. The conducted researches allowed to analyze and evaluate the ecological status of the surface waters of the Guyva River within the Zhytomyr region, which will allow to establish ecological standards of water quality and on this basis to determine the main directions for improvement of water resources and to substantiate the system of recommendations aimed at improving the ecological status of the studied basin.

The ecological assessment of the quality of surface water of the Dnipro basin (within Zhytomyr region) is carried out. In general, surface water of rivers of teter, rotten, Guiva, forest stone, Irsha, Human, Arpin, Rostavitsa and Kamyanka were investigated. The study was conducted according to systematic observations based on the ecological classification of the quality of surface water and estuates in Ukraine, which includes a set of hydrophysical, hydrochemical, hydrobiological and other indicators reflecting the peculiarities of components of aqueous ecosystems. On the basis of unified ecological criteria, the technique allows you to compare the water quality in separate areas of water objects, in water objects of different regions. The calculation of the ecological assessment of water quality was carried out within three blocks: a block of saline composition (I1), a block of troph-sanitary (ecological-sanitary) indicators (I2) and a block of indicators of specific substances of toxic action (I3). The results are presented in the form of a combined ecological assessment, based on the final conclusions of three blocks and is to calculate the integral ecological index (IE). The results of observations on the qualitative state of surface water in the Tetereva Basin, the right tributaries of the Dnieper “Good”, “clean” water (II class of quality) here are less than half (47%) of all observation points. Such a quality is the water of the rivers of Irsha, Guiva, rotten, varnia, teter. In 6% of cases, “satisfactory”, “contaminated” water of the quality of the quality (3,7 ≤ IE ≤5,4), namely: r. Teters, within the city of Zhytomyr, 200 m above the fall of the River Forest Kamyanka and River Forest Kamenka, within the city of Zhytomyr, 100 m above the fall in Teter. Waters of all other research points occupy an intermediate position between II and III of quality classes and are evaluated as “good”, “clean” and “satisfactory”, “contaminated”. The water of the pools Irpen and dew, represented by the rivers Irpin, Rostavitsa and Kamenka, are characterized by the second class of quality “good”, “clean”. Executed researches allowed to analyze and evaluate the ecological state of the rivers of the rivers of the Zhytomyr region within the Dnipro River basin, which will establish the environmental standards of water quality and to determine the basic areas for improving the state of water resources and substantiate the system of recommendations aimed at improving the environmental state of the basins under study in the boundary of the area.
