摘要
The paper aims to provide insight into data on leachate migration, composition, and migration time and to improve the engineered barrier system (EBS) importance through different pollutant concentrations in the landfill at the base of the unsaturated zone and off-site, for the real-case scenario with composite liners (EBS) and the worst-case scenario with no liners (NO EBS) using the LandSim software for 30, 100, 1000 and 20 000 years in 1000 iterations. Also, the paper aims to analyze the leachate leakage through the waste for different migration times and different internal layers to create a qualitative and quantitative basis for assessing leachate's impact on the environment. The results obtained by modeling the parameters of the real case at the Gigos landfill showed that the leachate leakage amount is about 340 times lower when EBS is present and concentrations of nitrogen, chlorides, arsenic, lead, cyanides, and mercury in the worst-case scenario (NO EBS) exceed the permitted limits according to the laws of the Republic of Serbia.
