Subject: the results of the analysis of the dynamics of changes in the quality of surface waters in the Lower Volga basin are presented based on the processing of statistical data on the long-term monitoring of their contamination degree. Significant all-season excesses of the maximum permissible values for the concentration of a whole range of background and anthropogenic pollutants in water were recorded. We identified the shortcomings of implementation of the existing methods that allow us to assess the dynamics of the state of the water basin ecosystem and choose the most essential parameters for constructing a mathematical model of selection of the most effective wastewater treatment technology. Research objectives: selection and evaluation of the input parameters of the mathematical model, the implementation of which will ensure the search for the optimal technology and appropriate technical solutions for cleaning surface sewage. Materials and methods: the conducted study is based on a comprehensive assessment of a wide range of hydro-chemical indicators of contamination of discharged wastewater in controlled locations using statistical methods for processing experimental data. Results: we identified the most essential parameters that allow us to form a conceptual model, and we determined the degree of their influence on the selection of the optimal solutions and methods of wastewater treatment. Conclusions: conclusions obtained during the study indicate the need for creation of a mathematical model of assessment of the quality of surface sewage treatment in urbanized areas for improvement of technological parameters of treatment facilities.

The Nenets Autonomous area located inside the Arctic circle is the subject of the Russian Federation. The environmental situation in the Nenets Autonomous area is poor despite the remoteness from other densely populated regions of Russia. A large number of ecosystems are exposed to powerful anthropogenic impact. For example, petroleum products and waste water exert negative impact on rivers and basins thereof. Water bodies in the region have some natural features which also adversely affect on water intake for industrial and domestic needs. The article considers and analyzes different types of pollution for natural resources of the Nenets Autonomous area which cause a great environmental damage to the region. Method of ranking for parts of the water body is proposed which makes it possible to reveal among them the most problematic from the environmental point of view. Options for improving the preliminary treatment of water at the water intakes are proposed that significantly simplify the operation of water treatment facilities. Сonstruction of new sewage treatment facilities using the latest developments in terms of tertiary treatment of wastewater, upgrade of standards for wastewater treatment, as well as the organization of sanitary protection zones will be a significant step in improving the environmental situation.
