MODELING OF HYDROGEOFILTRATION GROUNDWATER FIELD IN THE INFLUENCE ZONE OF METALLURGICAL PRODUCTION

In order to detect technogenic violations, the hydrogeofiltration field of the aquifer closer to the land surface which is spreading within the site of metallurgical production of the Private Joint Stock Company “EVRAZ Dniprovskyi Metallurgical Plant” (PJSC “EVRAZ DMP”) was investigated. The data of the target analysis and the groundwater monitoring information (2010–2014) from the PJSC “EVRAZ DMP” local groundwater monitoring networks were used. A full-scale survey of observation wells and pilot filter work was carried out. Geoinformation approach was used for modeling the hydrogeofiltration field of the investigated aquifer. According to the results of geoinformation analysis, the presence of disturbances of level, balance and hydrogeotermal parameters of particular aquifer were observed. It was discovered the local “piezometric dome” perturbations of the water table and the stable abnormal groundwater temperature rise. Such changes indicate the presence of additional intensive anthropogenic sources of infiltration in local areas. The most relative level of water-ecological load is obtained the southwest zone of the industrial site with a borderline location. Therefore, the influence of the adjacent urbanized area on the deformation of the hydrogeofiltration field of the aquifer closer to the land surface within the studied area was not excluded. The preservation of the revealed tendencies of deformation of the hyd­rogeological conditions on the site might be produced a threat to safe ope­ration of industrial structures as a result of intensification of the floo­ding process and derivatives – mechanical and chemical phenomena.
