Evaluation of Contaminants Transport from Storage and Burial Places of Industrial and House-holding Wastes to the Dnieper River by Groundwater
The project goal was improving of surface and of groundwater quality, which were contaminated due to technogeneous leakage from different waste disposal sites (tailings storage, accumulating ponds etc.) in the lower part of the Dnieper river basin. While the project was performing, measures aimed at maximal limitation of filtration losses of contaminants from wastes storage to underground waters and to the Dnieper river was developed for the tailings storage of the Poltava Ore-Enrichment Plant. They allowed to decrease risk of environmental contamination and to increase ecological resistance of drinking water supply by means of increasing a deal of underground water using versus according decreasing of contaminated surface waters using.
As results of the project performance next items were obtained as follows:
— database with hydrogeological, engineer & geological, geochemical and another data, necessary for a filtration & migration model creation, as well as for long-term monitoring at the object;
— a filtration & migration model for solution of problems on forecasting of contaminants transport from disposal sites of liquid industrial and house-holding wastes with groundwater and their transfer to surface water and choice of engineer constructions type for underground and surface water protection on the example of the Poltava OEP;
— maps with ecological & geological content, including: map of condition of tap-water sources in the zone of influence of the Poltava OEP; map of sources of contamination of underground and surface waters; map of technogeneous changes of geological medium; map of forecast on ecological & hydrogeological conditions changes with taking into consideration the results of modeling;
— substantiation and choice of an optimal scheme of engineer measures aimed at protection ground- and surface waters from contamination.
