The extent of transfer, distribution, controlling geochemical factors and enrichment of heavy metals in Pangi area (NW Torbat Hydarieh, Iran) were investigated. Ten heavy metals and metalloids such as manganese (Mn), iron (Fe), arsenic (As), cadmium (Cd), chromium (Cr), nickel (Ni), Copper (Cu) Lead (Pb), Zinc (Zn) were analyzed using AAS and GFAAS. The mean metal pollution index (MPI) and heavy pollution index (HPI), in the Pangi and Targhi area were found to be above the critical pollution index values. Index of metal and heavy metal pollution index showed that 5 samples of water samples, not potable. The results indicate that multiple sources of pollution in the water resources of the region. The two main sources, one associated with the dominant lithology of ophiolite sequence in the region (extensive serpentinites as well as sulfide ores in dikes) and another, mining activities in the region. High values of Fe, As, Cu, Mn and Cr elements associated with lithologic units but high levels of Ni and Cr are associated with mining activities. High levels of Cd associated with fertilizers used in agriculture but high Pb must be obtained from the vehicle exhaust emissions (due to heavy road traffic). The enrichment factor (Ef) of heavy metals was in order of Mn > Fe > Pb >Ni > As > Cu > Cr > Zn > Cd in the study area.
