Modelling the Migration of Anthropogenic Pollution from Active Municipal Landfill in Groundwaters

Abstract Landfill requires a systematic monitoring of its impact on groundwater and surface waters. The paper presents the modeling pollution migration for cases when leachate penetrates aquifer layer. For this purpose, conceptual hydrodynamic model was developed in program Visual ModFlow Pro, which is spatial two-layer model. Chloride ion used as an indicator defining rate migration. results calculations soil-water conditions demonstrated that it practically impossible pollutants to penetrate aquifer, since sufficient protection provided by artificial insulation layer sandy clays. A potential can only occur after rupture – damage In such case, vertical infiltration will be taking place 4aeration zone relatively long period, while already saturation (hydrated) at high speed.
