Physicochemical Properties of Ground Water from Elfarshaya Area, Southern Kordufan State, (Sudan)
A. Gobara, Yagoub Abdalla Ali
Abstract: Well water is main source of drinking water in Elfarshaya area, In this study four samples of water were collected from Elfarshaya area in October (2019), and analyses were performed the following parameters: (pH, EC, TDS), hardness as CaCO3, cations: (Na+, K+ and Ca+2), an aions: (Cl-, SO4-2, CO3-2 and HCO3-). The results showed that the pH values ranging from (7.15 to 7.88), thus, all the samples were slightly alkaline (pH > 7). TDS values for all the samples in ranging from (98 to 273 ppm) were within the permissible value of WHO (1000 ppm). The results of chloride found in ranging from (22 140 ppm) were in agreement with WHO standards (250 ppm Cl-). The results showed that the concentration of sulphate for all the samples is (0.023 - 0.174 ppm) in permissible level of WHO. For hardness, two samples (63 - 72 ppm) were classified as moderately soft, and another two samples (140 - 186 ppm) were classified as slightly hard and moderately hard respectively. The concentration of cations: Na+ (12.3- 34.89 ppm), K+ (4.25 10.6 ppm) and Ca+2 (2.57 - 22.8 ppm) were within the permissible level of WHO (200 ppm Na+, 10 ppm K+ and 200ppm Ca2+). As the result of these findings the water can be use without treating. The study recommended that more of study to determine the trace metals.
