摘要：Ground water is the most important source of domestic and irrigation purpose in both rural and urban regions. The present study is carried out to find the ground water quality by heavy metal concentration from three sites. Nine heavy metals were selected (Cd, Pb, Cr, As, Cu, Hg, Se, Zn and Ni). It was showed that concentration values were 0.0016-0.0016, 0.003-0.00, 0.006-0.00, 0.00-0.004 and 0.002 mg/L, respectively. To assess ground water quality which contaminated by heavy metals, four indices were selected as follow: heavy metal pollution index (HPI), contamination index (Cd), metal enrichment index (MEI) and metal evaluation index (HEI). Results showed that the concentrations of heavy metals in water samples are within the permissible WHO limits in drinking water. Three metals of them (AS, Hg and Se) were not detected in all sampling stations. MEI in the ground water samples show that Ni is the highest metal enrichment value of -0.6. HPI of water samples in three sites were 20.57 which was lower than 100 the critical value for drinking water. Cd shows that the values vary between -5.1 to -0.3 which indicate low contamination. HEI shows that the values in spring season vary from 0.001 to 0.66 and indicate low heavy metal pollution. Results show that ground water of the present study is acceptable for drinking.
