Abstract:
The aim of this study was to evaluate the seasonal variation effects on drinking water quality at Southern Kordofan state. Ground and surface water samples were collected from the same sources during autumn and winter seasons. The sampling covered the thirteen localities of the state. pH, EC, and TDS values were measured. The concentrations of and were determined by UV-Vis spectrophotometer. Chloride content was titrimetrically measured. Minerals Inductively coupled plasma analysis was carried for measuring minerals content. The obtained results showed clear seasonal variations in TDS, EC, pH values,,, and . Na and K concentrations were higher in winter. The concentrations of Ca and Mg in winter sometimes increase or decrease than that of autumn for ground water samples, but showed regular increasing in surface water samples. The trace minerals concentrations were significantly low in the two seasons and only Fe, Al and Cu showed minor seasonal variations. According to WHO SSMO guidelines values all the studied water sources may be good, suitable and safe as drinking water sources.
