The hydrochemical composition of waste percolating water (leachate) generated in MSW landfills was investigated and analyzed. On the example of the MSW landfill in the city of Zhytomyr (Ukraine), the component percentage in the leachate was determined. The initial data for the research were hydrochemical indicators of leachate samples from dumps of the landfill for the period 2009–2016. The analysis of the leachate revealed the component percentage. It was found that chemicals such as phosphates, iron, cobalt, cadmium, lead, chemical and biochemical oxygen demand, alkalinity and hardness indicators of leachate in Zhytomyr MSW landfill exceed the maximum permissible concentrations.The experimental data were obtained, and their features, summarized in the form of regression equations and corresponding approximating curves, which give information on the dynamics of quantitative composition of chemical components in leachate samples from the landfill sumps were identified. The reliability coefficients of these equations were found. The resulting regression equations are the basis for forecasting the pollution processes of percolating water of Zhytomyr MSW landfill. These models will also contribute to the development and implementation of practical measures for decontamination of leachate from MSW landfill sumps, minimization of harmful effects on the hydrosphere in the final stages of the landfill life cycle.
