The definition of the scientific and instrumental basis for geoecological assessment, as well as the rehabilitation of internal watercourses of residential territory is one of the most relevant areas of activity in geoecology. Scientific approaches in the field of methodology for the study of water bodies are the basis of geoecological studies aimed at the ecological rehabilitation of aquatic complexes, on the basis of which methods are being developed to select priority actions aimed at the ecological rehabilitation of urban watercourses. This article formulates approaches from the point of view of environmental safety of water bodies in conditions of intense anthropogenic impact on the example of intracity aquatic complexes of the city of Astrakhan. The climatic and geological conditions of the research object are analyzed. The causes of degradation of the ecological state of watercourses have been established, the main factors and sources of anthropogenic impact have been identified, taking into account the role of polluted surface runoff from catchment areas.
Key words: surface water quality, geoecological assessment, aquatic complexes, urbanized territory, geochemical analysis, laboratory studies, environmental monitoring, environmental rehabilitation, anthropogenic load, methods of analysis of urban reservoirs
