Concentrations of six elements were examined in water. Average concentration obtained from  AAS analysis of the samples showed Ni (0.60), Fe (0.80), Cd (0.14), Cr (0.38), Pb (0.84), and Mn (0.73) in (mg/L). The concentration varied in the order: Pb>Fe>Mn>Ni>Cr>Cd for water samples. It was observed that the trend of EDIs for heavy metals in the water samples analyzed increased in the order: Fe>Mn>Ni>Pb >Cr>Cd. The HRIs of Ni, Mn, Cr and Fe were lower than 1 (HRI >1) except for Cd and Pb, with Carcinogenic Risk values of Ni (0.0041), Fe (0.0063), Cd (0.0076), Cr (0.0010), Pb (0.00), and Mn (0.0057), respectively.
