Abstarct: The Cheshmeh Hafez poly-mextalic (Pb, Zn, Cu, Ag and Au) deposit is located in the Torud-Chahshirin volcanic belt, central Iran zone. Main rock units of the area include basalt, trachyte and trachyte – andesite. A series of old mining activities conducted in the area that were fallowed by depoting of large volumes of ores and mine wastes. Exposing of this material to the air and surface water caused to releasing and transport of potentially toxic elements from the ores and caused the distribution of the elements in the secondry environments such as water, soil and sediment. In this study, pollution of sediment and groundwater in the Cheshmeh Hafez area by heavy elements was evaluated. For this purpose, water and sediment samples collected from the area were analyzed using indoced coupled- plasma mass spectrometry (ICP-MS) method for determining concentration of minor and trace elements. Then some of the elements were slected for evaluation of intensity of contamination baxsed on their environmental significance and their concentration. therefor As, Cu, Pb, Zn, Cd, Au, Ag, Co, Cr, Mn, Ni, Sb, Bi and Fe were evaluated. The geochemical factors such as enrichment factor (EF), geoaccumulation index (Igeo) and contamination factor (CF) were used for quantifying the severity of pollutions. As well for determining amount of relationship of elements with each other paramiteres such as pH and organic matter percent, the Kendall correlation coefficient was used. The results show that contamination of some elements and heavy mextals contamination is very high in the sediments. This contamination exists naturally in the region due to mineralization, but the anthropogenic activity (mining), has intensified it. Natural arsenic contamination in the sediments is clearly visible. Mining activities have had major effects on the releasing of copper, lead, zinc, silver and gold in the sediments of the region. baxsed on the average Igeo of the elements, the area generally shows intensive lead contamination, and medium copper, silver, gold, cadmium and zinc contamination. The other elements do not show any contamination. The groundwaters of the area in the case of quality parameters have not undesirable situation. Because the anion and cation concentrations in the waters is very high, several than the standards. The electrical conductivity of the waters reached above 1700 μM/cm. With regard to concentrations of heavy mextals and toxic elements one sample is intensively contaminated with gold, bismuth, cadmium and antimony while another samples is little contaminated with lead. Other samples do not show any contamination.
