This paper presents the construction of a numerical three-dimensional model area Żelazny Most Mining Waste Storage Facility (MWSF). In study area, difficult geological conditions associated with glaciotectonics are accompanied by complex hydrotechnical system sediment deposition and sedimentary water drainage. order to effectively reflect flow paths, detailed schematization was carried out, using 700,000 boreholes more than 300 hydrogeological cross-sections. addition, numerous drainage sections, streams, ditches were included reliably assess amount saline entering underlying aquifers. research supported magnetic resonance sounding (MRS) studies reservoir’s sediments. The MWSF is currently being expanded, so work primarily focuses on illustrating changes in hydrodynamic field resulting from inclusion new southern section. Models similar facilities have been implemented before, but current one, combination meticulous analysis hydro-structural system, balance, significant data, size facility, use an unstructured discretization grid calculations undoubtedly innovative will be important contribution development analogous solutions around world.

The present study focuses on a site contaminated with halogenated hydrocarbons, utilizing detailed inventory of contamination data to achieve the precise characterization groundwater pollution. Employing MOFLOW-2000 software, flow model was established for area. In conjunction MT3DMS, predictive constructed simulate and forecast spatiotemporal distribution contaminant migration attenuation following remediation. simulation area delineated based geographical features, vertical range strata also determined. To establish hydrogeological conceptual target remediation site, comprehensive were collected, encompassing geological structures, hydrological parameters, rainfall information. Model calibration six layers low-permeability aquifer intervals revealed by exploration wells MW1–5, as well groundwater-level contours data. Based from September 2010, an initial three-dimensional tetrachloroethylene (PCE) generated. Subsequently, solute transport PCE established, incorporating various enhanced reductive dechlorination (ERD) strategies applied at different times locations. Calibration against actual monitoring presence unmonitored dense non-aqueous phase liquids (DNAPLs) contributing continuous release elevation concentrations. By accounting DNAPL release, calibrated closely matched observed concentration decay patterns, effectively capturing dynamics within system. modeling approach proposed in this provides important support current it is applicable simulating predicting pollution scenarios similar sites.
