| Abstract | ||
| Tanjero river represents a permanent river located southwest of Sulaimani city about 7km. Qiliasan and Kani-Ban streams confluence to form Tanjero river near Kani-Goma village. Water samples were collected from fifteen sites along the Tanjero river during June 2007 up to January 2008 and analyzed for studying some physico-chemical properties and heavy metals contaminations. The total hardness values recorded in the studied sites were ranged ( 204.96 – 388.06 )mg/L.The values of (8-33.1) ºC, (1.08-496) NTU were recorded for temperature and turbidity respectively, while the values of (0.64 - 9.19) mg / L, (7.26-8.64) and (362 – 1715) µS.Cm-1 were recorded for dissolved oxygen (DO), pH and specific conductance. The values of Cobalt (Co), Chromium (Cr) ,Iron (Fe), Manganese (Mn) and Nickel (Ni), concentration were ranged between, (1.80 to 2.39), (0.2 to 3.31) , (2.13 to 2.55), (0.08 to 3.29) ,and (0.51 to 1.72) mg/L respectively . The result indicates significant differences (P≥ 0.05) for the sampling events with LSD (Least Significant Differences) value of 0.01 for Co Fe, and Ni, while 0.03 and, 0.06 for Cr and Mn respectively. The Copper(Cu) concentration in all studied water samples was within the acceptable levels which ranged (0.11 to 0.51) mg/L . Tanjero river and tributaries were polluted with heavy metals (Fe, Mn, Ni, and Cr) resulted from the impact of sewage wastewater according to water quality standard EU, 2004; USEPA, 2005; Canada, 2005 and WHO, 2006 and should Construct a plant of treatment for treating sewage wastewater of Sulaimani city before direct discharge to the river and it is quite essential to treat the ground water of the studied area before using . | ||
