Abstract Background & objectives: Heavy metal pollution of the environment on a global scale is a problem now. heavy metals due to the chemical stability, low flexibility and power of bio-accumulate in the body organism are quickly becoming toxic pollutants. Therefore purpose of this study survey heavy metal concentration and comparing the results with national and international standards and also health risk assessment in carcinogenicity and noncarcinogenicity took in the Ali Abad Katoul region. Material & Methods: This research was performed with temporary description method in 2009 autumn and 2010 spring. During this research have been chosen about 36 samples from 6 wells that supply drinking water to rural and heavy metal (arsenic, lead, Zinc, chromium, cadmium) was measured based on method standard 1988 with atomic absorbtion. also the human health risk assessment was measured by using the criteria of the enviromental protection Agency (EPA). Results: Heavy metal concentrations average in autumn Zn=0.0143, Pb=0.0060,Cr=0.0025, As=0.0022, Cd=0.00 and in spring Zn=0.0045, Pb=0.0066, Cr=0.0023, As=0.0009, Cd=0.00 mg/l was obtanied. The results showed there is not any statistically significant differences between concentrations of heavy metals in national and international standards. Results of health risk assessment of heavy metals for residents uring the period was measured, for carcinogenicity diseases 2.32 × 10-4 individual and for noncarcinogenicity diseases 2.53 ×10-4 individual. Conclusion: Heavy metal results was measured and comparing them with standards showed that there is no treatment from sanitary in studied area. But with increasing population and pollution and disease It may be observed changes in the concentrations of heavy metals in future. Therefore it is essential to be continuously monitored for heavy metals
