WATER BODIES POLLUTION OF THE MINING AND CHEMICAL ENTERPRISE
Abstract
Water resources are the national wealth of any country and one of the basic foundations of its economic development. The growth of cities, rapid industrial development, intensification of agriculture, a significant expansion of irrigated land and many other factors make the problems of rational water resource management more difficult. The activity of the mining and chemical enterprise mainly leads to the soil and the water pollution. After the closure of the enterprise, it is necessary to develop a remediation project and timely implement the remediation process. Special attention should be paid to the water environment pollution problem. Rozdil State Mining and Chemical Enterprise (SMCE) ?Sirka? has been standing on the stage of liquidation since 2003. Its territory includes tonnes of industrial wastes that pollute soils and water bodies. The purpose of the work is determination of the trends of changes in the pollution of the water environment of Rozdil SMCE ?Sirka?. Experimental research has established that there is the excess of the normative indicators for mineralization and sulphates in the surface water layer of all man-made lakes of the enterprise. There is the excess of the normative indicators for mineralization, sulphates and phosphates in Lake Kysle and Lake Serednie. In 2017 the pH is 5.25 in Lake Kysle, the normative level should be between 6.5 and 8.5. In the channel Lake Hlyboke-Dniester River is the excess of the MPC on the indicators: pH, sulphates, ammonium nitrogen, mineralization. The discharging contaminated wastewater into the Dniester River is a violation of the 44, 70, 95 Articles of the Water Code of Ukraine. The pollution of water bodies of the enterprise has increased in 2017 in comparison to 2014. This is mainly due to the non-implementation of the liquidation project of the territory. On the example of Rozdil SMCE ?Sirka?, trends of changes in the state of the water environment were identified in connection with the non-implementation of the process of rehabilitation of the territory of the mining and chemical enterprise.
