Monitoring of ground and surface water in the area of hazardous industrial waste disposal enterprises

On the territory of the Mirny Ecotechnopark, a production and technical complex for processing, recycling and rendering harmless waste of I and II hazard classes, it is planned to conduct environmental monitoring of all natural environments and objects within the framework of the integrated environmental monitoring program. This paper presents some principles and approaches to organizing the monitoring of groundwater and surface water, bottom sediments. It is shown that when organizing the monitoring of the created object, it is necessary to take into account the features of the monitoring system of previously existing objects in this territory and the results of long-term observations of the state of natural waters in this area. In particular, when organizing the monitoring network, it is recommended to use observation wells drilled to monitor chemical weapons storage and destruction facilities. When selecting monitoring indicators, it is necessary to take into account elevated concentrations of pollutants and indicators indicating deterioration in water quality identified during monitoring of existing objects. It is recommended to include 38 indicators in the list of environmental monitoring of the facility being created for groundwater, and 40 for surface water. To form a priority list of observed parameters of natural waters and water bodies, a logarithmic index of pollutant toxicity based on toxicity classes and maximum permissible concentration values is proposed. It is recommended to use bioindication and biotesting methods to assess the state of natural waters and bottom sediments, in particular, to conduct an analysis of the taxonomic composition of bottom invertebrates and quantitative indicators of benthic communities, as well as a qualitative assessment of the state of water bodies using bioindication indices.
