| Abstract | ||
| (10) Water samples were collected from Diyala River within Baqubah City, in addition to two water samples, one sample from Diyala River before Baqubah city and the other one after the city. (4) Sewage water samples were collected to the influence of sewage water on the quality of Diyala River which is discharged directly to the river without treatment, sampling campaign achieved in February / 2011. Chemical analysis were conducted to measure the concentrations of major contents & trace elements (Pb, Cd, Zn, Cu & Ni) to estimate the environmental situation for Diyala River and its uses for different purposes. The results revealed that the water samples have high concentration of some major contents especially (Mg & Ca) whereas the sewage water has high concentrations of (K, SO4 & Ca) according to the drinking water criteria of (WHO), Sodium Adsorption Ratio (SAR) in the water samples was less than (10) & it’s suitable to use as irrigation water according to their Sodium content while the mean of total hardness (TH) was above the international limits according to the drinking water criteria of (WHO) and Iraqi limits, therefore it’s classified as hard water, Water type for the most water samples was (Ca- Mg- SO4 – Cl – Bicarbonate). The comparison with drinking water criteria was done to see the possibility of using the water of Diyala River as drinking water as well as the obtained results compared with animal’s drinking water criteria and with the irrigation water criteria. Some trace elements (Pb, Cd, Zn, Cu & Ni) were chosen to measure their levels in Diyala River; the concentrations of (Pb, Cd & Ni) were above the international limits according to the drinking water criteria of (WHO) whereas (Zn & Cu) were under these limits, the increasing in the concentrations of some trace elements is due to the sewage water & domestic waste which discharge directly to the Diyala River without treatment. | ||
