Temanggung Landfill is equipped with a liner system that consists of gravel, geotextile, geomembrane, and compacted clay. However, there is still potential for contaminant mobilization through liners to the surrounding environment, especially the soil beneath the landfill. The purpose of this research is to simulate the movement of lead (Pb) in landfill, vertically at every depth. Contaminant migration from landfill across time can be predicted using POLLUTEv7 software, a one-dimensional model that can describe contaminant mobilization affected by dispersion, advection, diffusion, and retardation phenomena. Over a period of 15 years simulated by the model, the concentration of Pb increased continuously. The initial concentration of Pb above the liner was 0.56 mg/l. This level dropped to 0.35 mg/l after passing the liner in the first year, then increased to 0.4106 mg/l in the second year, and kept increasing up to 0.5071 mg/l in the 15th year.
