The intense process of urbanization has led to a number of environmental problems associated with the sharp deterioration of water quality of aquatic systems of the urban environment. Efficiency of solving environmental management of urban areas in technogenesis largely depends on the completeness and accuracy used for this purpose information on the status of water bodies. On the basis of studies assessed the reservoirs of the urbanized areas in the example of the city of Astrakhan. Given the results of research from 2010 to 2014. As the main source served the materials of geoenvironmental studies conducted bioassay methods aquatic complexes in the urban environment. Identified the main sources of contamination of aquatic systems and ways of solving optimization problems negative impact of contaminants on the aquatic environment. Relevance of research topic due to the fact that the tendency of environmental degradation of the small rivers of Astrakhan, their exhaustion, not least due to the imperfection of environmental law, including in the sphere of water legislation. Currently, the analysis of the quality of the aquatic environment is not only environmental but also economic importance, due to the need to assess the suitability of water for recreational, household, food and other purposes. All this requires the use of fast, good reproducibility, adequate and inexpensive methods of testing.
