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.
