Landfill sites are one of the most important sources of contaminant entry to the environment. In this research, the concentrations of Cu, Pb, Ni, Cd, and organic compound BPA in Hamadan landfill were evaluated to determine the status of its burial environment in 2014. Seven water samples (2 samples from spring and 5 samples from well), 2 leachate samples and 15 soil samples were collected from Hamadan landfill. Evaluation of the concentrations of Cu, Pb, Ni, Cd and the organic compound BPA was done by atomic absorption and gas chromatography with mass spectrometry. The concentrations of metals (Cu, Pb, Ni and Cd) in water samples (wells and springs) Pb <Cu <Cd <Ni, the leachate samples Cu <Pb <Ni <Cd and finally, the soil samples Cd <Cu <Pb <Ni, were obtained, respectively. Water samples (wells and springs), only in a 7W handheld water well sample (the nearest to the buried well) related to BPA 22.35 (μg /l) composition, waste leachate samples for the concentrations of BPA, 103.3 (μg /l), and soil samples for the combined concentration of BPA 5.52 (ng /g) were obtained. High concentrations of Ni, Pd and Cd and high concentrations of BPA in the samples of leachate composition, soil samples of landfill, and the 7W handheld water well samples were due to the high volume of electronic waste and plastic waste.
