This study proposes to investigate the environmental impact caused by heavy metal contamination on soil and surface water from the non-sanitary waste municipal landfill “Pata Rat“ from Cluj-Napoca Romania. The samples were analyzed with atomic absorption spectrometer (AAS). The evaluation of the analysis results proves that there is high pollution in soil with some heavy metals (Pb, Cu). The heavy metals content was investigated also in water samples from Zapodie stream that flows near the landfill and in leachate collected from the same landfill. The overall view of the study presents a recent evaluation of the pollution with heavy metals attributed to the exploitation of the landfill for over 37 years, and establishes the influence and the transfer mode on environmental contamination.
