| Abstract | ||
| Hydrochemistry of Diyala River (Middle-Lower Basin) was studied in order to determine the physical, chemical properties, water quality, pollution, the influence of human activities and natural processes. Ten water samples were collected along Diyala River from Kelar region to the meeting point of Diyala river and Tigris river southern Baghdad city. The physical properties included hydrogen number (pH), total dissolved solids (TDS) and electrical conductivity (EC), but in term of chemical properties, samples were chemically analyzed for cations and anions (Ca+2, Mg+2, Na+1, K+1, Cl-1, HCO3-1, SO4-2, NO3-1). The results of physical properties had been shown that the pH is within acceptable limits according to the WHO, 2006 guideline and Iraqi guideline, 2009 for drinking water, while the TDS, EC values are higher than the acceptable limits of the mentioned guidelines. The average concentrations of the following cations and anions: ( Ca+2, Na+1, Cl-1, SO4-2) are higher than acceptable limits, but the average concentrations of anions ( Mg+2, K+1,HCO3-1,NO3-1) are within acceptable limits of WHO, 2006 guideline and Iraqi guideline, 2009 for drinking water. The dominated cations in Diyala River are Na+1, Ca +2 and the dominated anions are Cl- 1, SO4-2 whereas the evaporation process is dominating in the river. The water quality is Na-Ca-Mg-SO4-Chloride, the results showed that the river water is very hard and most of the physical and chemical properties are higher than acceptable limits, so it is unsuitable for drinking. From calculating sodium adsorption ratio (SAR) the river water appear to be suitable for irrigation and it is appear to be classified as S1 Level, which is no harmful regarding sodium. It appears that the wrong use of water in Diyala basin and unprogrammed use of fertilizes, effect of trocars, the influences of industrial wastes, sewage sludge, human activities, all these factors contributed for worsen the quality of Diyala river water. | ||
