As the main sources of water supply to the villages are springs, this study evaluated cyanide concentration of village springs nearby the Agh-Darreh and Zarehshuran gold extraction plants in Takab city in 2011 and zoned it by geographical information system (GIS). Mean water temperature, pH, Electrical conductively, total dissolved solids, salinity and cyanide content of studied springs was 14.89±2.482 °C, 7.38±0.368, 656.3±397.45 μs/cm, 319.135±199.34 mg/l, 0.32±0.199% and 0.004± 0.0017 unit, respectively. Except cyanide concentrations the other parameters value in studied springs had significant different (P<0.05) than what. Correlation analysis showed the concentration of cyanide in the springs water sample and the distance from gold extraction plants has a significant reversed relationship (P<0.0001and r = -0.72). As obtained results showed those springs are closer to the gold extraction plants has more Cyanide in water samples. The use of GIS is very useful to explain the results visually as a picture. GIS can show results integrated and clearly, so it is understandable for non-expert person.
