ON SOME ASPECTS OF THE ASSESSMENT OF NEGATIVE ANTHROPOGENIC IMPACT ON THE QUALITY OF SURFACE WATER BODIES IN THE ENVIRONMENTAL SAFETY ENSURING SYSTEM
Abstract
Aim. The aim of the research is to determine the objectivity and reliability of the information received on the quality of surface water bodies, taking into account the natural features of water bodies in the Specific Combinatorial Water Pollution Index. Methods. Basic information about the quality of surface land waters (including small rivers) was obtained during regime observations, which were carried out by the Federal State Budgetary Institution "West-Siberian Service for Hydrometeorology and Environmental Monitoring" in 2017. Assessment of the degrees of contamination of surface waters was carried out on the basis of statistical processing of the results of chemical analyzes “Gydrokhimik PC” software package and indicators of a comprehensive assessment of the degree of contamination of surface waters calculated using the “UKISV-network” software package. Assessment of the degree of pollution of surface waters is based on the data of the West Siberian Research Institute for Aquatic Bioresources and Aquaculture for 2017. Results. It has been established that the quality assessment methodology by the Specific Combinatorial Water Pollution Index does not objectively evaluate the quality of surface water bodies taking into account the natural features of water bodies. Conclusion. It is necessary to improve or change the approaches and methods of assessing the quality of surface waters since this will increase the degree of reliability of statistical information. In turn, this will allow the authorities and relevant federal agencies to respond more quickly to issues of ensuring environmental safety, it will also allow using the budget funds allocated for environmental protection more rationally.
