The main sources of chemical pollution of surface water bodies of Ukraine are shown and it is noted that the ecosystem of the environment and water resources, being under constant man-caused load, tend to steadily deteriorate the ecological condition. Methods for assessing the quality of surface waters using the maximum allowable concentrations of harmful substances in water and a comprehensive assessment of the ecological status of surface water by integrated hydrochemical parameters are described. International approaches to the assessment of the state of surface water bodies are considered. It is noted that the most complete information on the state of the aquatic ecosystem can be obtained using a set of physicochemical and biological parameters. There are shortcomings in the monitoring of organic micro-pollutants in surface waters. The analysis of the international experience of determination of water quality and parameters of toxicological action of organic micro-pollutants with application of chemo-informative methods for modeling of an ecological condition of water systems is carried out.
