Determination of some Inorganic Constituents of Ground Water in AboZabad Area and comparing it with the international specification of Drinking Water

الملخص

In this study four samples of ground water were collected from Abo-Zabad  area (Abo-Zabad City, Garelasal Village, Abo-Galeb village and Khammas Elduonky village) West Kordofan State  and  analyses were performed the following: (pH, EC, TDS), anions : ( Cl^-  , SO₄^-2 ,CO₃^-2 and HCO₃^- ), hardness as CaCO₃, cations: (Na⁺, K⁺ and Ca⁺² ). The results showed that the pH values for all the samples fall between (7.9-8.4) hence all the samples were alkaline (pH > 7). The results of electrical conductivity (EC) for all the samples between (132-635 µmohs/cm. The total dissolved solids (TDS) values for all the samples between (79 - 381 ppm). The results of chloride ion (Cl^-) concentration for all the samples falls between (16.4-82 ppm).The results showed that the concentration of sulphate ion (SO₄^-2) for all the samples between (0.08 - 0.329 ppm). The results showed that the concentration of carbonate ion (CO₃^-2) for all the samples between (102-198 ppm). Also the results showed that the concentration of bicarbonate ion (HCO₃^-) for all the samples between (117.6-253.1ppm) in permissible level of WHO standards (500 ppm). For hardness, two samples (150-160 ppm) (A and B) water of (Abo-Zabad City and Garelasal Village)  were classified as moderately hard respectively and other two samples (20 -290 ppm) (C and D) water of (Abo-Galeb village and Khammas Elduonky village) were classified as hard respectively. The concentration of cations: Na⁺ between(13.66 – 39.8 ppm), K⁺  between (3.11 - 4.20 ppm) and Ca⁺² between(88- 120 ppm) for all the samples were within the permissible level of WHO standards (200 ppm Na⁺, 10 ppm K⁺ and 200ppm Ca⁺²). From the study all water samples were accepted for all purposes.
