Abstract
The current state of surface water quality is stable, but it is characterized by a number of problems that collectively call into question the effectiveness of the current water management system in the country. Over a long period of time, the volume of pollutants entering the uncontrolled, mainly diffuse, runoff to water bodies determines the unsatisfactory quality of natural waters and the poor environmental condition of water bodies. This is a consequence of the imperfection of the current water management system.
Highlights
Among the urgent scientific and technological problems of the Russian water sector, the priority ones are the poor regulatory framework, the economic mechanism of water use as well as poor monitoring system and wastewater treatment technologies used on-sites
In Russia, the maximum permissible concentrations (MPC) value was developed only for petroleum products belonging to the hydrocarbon group (HC) as a whole
It does not take into account the toxicity specific to all individual HCs, the variability of the composition of the original oil, and the fact that oil as a mixture of HCs and HCs included in its composition are subject to transformations in the aquatic environment
Summary
Among the urgent scientific and technological problems of the Russian water sector, the priority ones are the poor regulatory framework, the economic mechanism of water use as well as poor monitoring system and wastewater treatment technologies used on-sites. We are lagging behind in measures to limit diffuse flow of runoff from catchment and residential areas, waste disposal, water protection from xenobiotics (pharmaceuticals, household, agricultural and industrial chemicals, etc.) and a risk-based approach to management
