Abstract:
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.
