Water, as the primary human needs, play a vital role in all aspects of our life, such as social environment, production, the economy, food security, and politics. In the present investigation, Heavy Metals (HM) concentrations including Cr, Pb, and Cd, have been ascertained in drinking water resources. Besides, point estimation using Hazard Quotient (HQ) and Hazard Index (HI) formula and sensitivity analysis (SA) using the Monte Carlo Simulation technique, by 10,000 repetitions in Oracle Crystal Ball®, were applied to demonstrate the non-carcinogenic effects of HMs on different exposed populations (Infant, children, teenagers, and adults groups). According to the results, the concentrations of Cr, Pb, and Cd in water resources ranged from 2.2 to 173.7 µg/L, 0.5 to 10 µg/L, and 0.2 to 0.9 µg/L, respectively. The results also showed that HI values were in the order of Pb>Cd >Cr. The results of SA, to determine the most effective parameter in increasing non-carcinogenic risk, showed that the concentration parameter of studied HMs had the most effect on increasing sensitivity in the four studied exposed groups.
