An analysis of the quality of surface water of State Enterprise “Rozdil Mining and Chemical Enterprise “Sirka”” was carried out. It was established that in order to ensure ecological balance in the zone of influence of State Enterprise “Rozdil Mining and Chemical Enterprise “Sirka”” it is necessary to conduct regular monitoring observations, maintenance, supervision and control over the condition of hydraulic structures, elimination of sources of pollution. The obtained research results indicate that there is a need to create an information and analytical monitoring system in order to effectively store, process, and analyze the data based on the principles of comprehensive environmental monitoring for the collection, storage, and processing of data on pollution of various elements of the environment, which will provide forecasting of environmental changes in the territory of the mining and chemical enterprise. On the basis of the obtained research results, a web application was created based on an interactive map of water sampling points, visualization of the obtained results of hydrochemical monitoring of Rozdil Lakes, and a forecast of the state of the water environment.
