Abstract
In the present study, from April to August 2010, twelve sites of groundwater within Sulaimani Governorate ( Sharawany, Mama Yara, Peshasazy, Twi Malik, and Ibrahim Pasha) were selected in order to evaluate some physico – chemical characteristics and seasonal analysis (Spring, Summer, and Autumn ) for heavy metals ( Cr, Zn, Ni, Cd, and Pb ). The results showed the range of studied parameters as following: 19.6 ºc-24.4 ºc for water temperature. pH value of the study sites range from 7.14-8.48 and 201, 50 - 943 μs.cm-1 for Electrical conductivity. Heavy metals content of Chrome (Cr), Zinc (Zn), Nickel (Ni), Cadmium (Cd), and Lead (Pb) for each seasons ( Spring , Summer and Autumn ) in groundwater determined, Chrome concentration in water samples were 0 – 0.002 mg.l-1, 0 – 0.003 mg.l-1 and 0 – 0.002 mg.l-1 for all seasons respectively . On the other hand Zinc was ranged in water samples during Spring , Summer ,and Autumn from 0 – 3.759 mg.l-1 , 0 - 1.887 mg.l-1 0 – 0.026 mg.l-1 respectively While Nickel concentration were ranged between 0 – 0.002 mg.l-1 in Spring, 0 – 0.004 mg.l-1 in summer below detectable level ( BDL) in Autumn. Cadmium in the water samples ranged between 0 – 0.001 mg.l-1 for all seasons. Lead is the other metal was determined in groundwater ,it was below detectable level ( BDL) during Spring , and 0 – 0.001 mg.l-1, 0 – 0.007 mg.l-1 for Summer and Autumn respectively.
