Evaluation of some physical and chemical characteristics of the drinking water collected after winter and autumn seasons from Kosti and Rabak Cities, White Nile State, Sudan

Drinking water quality is a very important issue in the health sector and it involve the check of some physical, chemical and biological parameters through some standard methods and limits. The current study aimed to determine some physical and chemical parameters of the drinking water collected from White Nile after autumn and winter seasons. The drinking water samples were collected from Kosti and Rabak Cities, White Nile State, Sudan, in clean disposable plastic bottles from random sites of each city. The determinations of the physiochemical tests were performed within one week after sample collection at University of Gezira Laboratories. The results of this study show that, the drinking water that collected after winter season showed good physical quality, as same as that collected after autumn season except the slight problem in color (less transparent). The tested chemical parameters of Kosti and Rabak drinking water that collected after winter season showed good quality except, those of sulphate, carbonate (0 mg/L) and chloride of 28.4 and 31.95 (ppm) as same as that collected after autumn season, except hardness (500 mg/L) which seemed to be an autumn problem of Rabak city. Although there were some signs of physical and chemical pollutions, serious steps towards treatment of their causes should be done.
