Abstract: The state of the water ecosystem of the Chornyi Tshlyk River near the location of JSC «Kirovogradgranit » reflects an increase in the man-caused load, which causes the process of its degradation. The work assesses the quality of the waters of the Chornyi Tashlyk River within the limits of the Dobrovolechkivsky district of the Kirovograd region.The purpose of the study is to assess the impact of pollutants entering the Chornyi Tashlyk River during the discharges of the waste water of the enterprise for its work on the full (design) capacity. The object of the study is the quality of the waters of the Chornyi Tshlyk River and the waste water of the enterprise. The scientific contribution is to improve the current methodology for calculating the concentrations of the maximum permissible discharges of the enterprise in terms of adjusting the conditional background and in checking the calculations. Initial data provided by the laboratory of JSC «Kirovogradgranit» Pomichnyansky quarry for river and sewage for the period from 2011 to 2016. Normative-technical documentation was provided by the Environmental Protection Department of JSC «Kirovogradgranit». The assessment of the quality of water was carried out using the method of detailed analysis. It is based on measuring or calculating the value of each indicator for assessing the quality of water and is comparable to its standard (MPC). According to the results obtained, we can conclude that the suitability or suitability of water for certain needs. Data analysis shows that the state of the Chornyi Tashlyk River does not meet the sanitary norms established for water utility objects: there is an excess of the MPC for the COD, BOD5, sulphates, total iron, copper, zinc and chromium (VI). Other indicators are within the normal range.
