Abstract


Characteristics of leachate are influenced by the type of waste that goes to landfill. Leachate of TPA Ngronggo Salatiga containing heavy metal of iron (Fe) and nickel (Ni). Due to the toxicity of leachate, it is necessary to prevent the leakage with using liner system in order not to contaminate the soil arround landfill. To predict pollution that caused by contaminant transport of leachate, can be done modelling use Pollute v7. In this model, transport of leachate is influenced by process of difution, dispersion and sorption in soil. The result of prediction contaminant transport of leachate during the life time of landfill for 15 years, can be use to evaluate the liner system of landfill. So can minimize the pollution of leachate.

Keywords


contaminant transport, pollute v7, heavy metal iron and nikel
