Abstract:
In this study four samples of ground water were collected from Elnuhud area (Elnuhud City, Wadbanda
City, Elbaltagy village Abukheratesh village) West Kordofan State - Sudan ,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 for all sample falls
between (7.05 - 7.78), hence all the samples were slightly alkaline (pH > 7). The results of electrical
conductivity (EC) for all the samples between (145 -538 µmohs/cm) were in agreement with those
values reported by WHO standards.TDS values for all the samples falls between (88 - 370 ppm) were
within the permissible value of WHO (1000 ppm). The results of chloride ion (Cl-
) concentration for
all the samples falls between (23.8 - 129 ppm) were in agreement with WHO standards (250 ppm Cl-
)
.The results showed that the concentration of sulfate for all the samples is (0.05 - 0.164 ppm) in
permissible level of WHO standards (400ppm). The results showed that the concentration of carbonate
ion (CO3
-2
) for all the samples between (24-48 ppm).Also the results showed that the concentration of
bicarbonate ion (HCO3
-
) for all the samples between (42.7-61ppm) in permissible level of WHO
standards (500 ppm). For hardness, two samples (A and B) (70 - 86 ppm) were classified as moderately
soft, and another two samples (C and D) (136 - 190 ppm) were classified as slightly hard and
moderately hard respectively. The concentration of cations: Na+
between (9.78 - 40 ppm), K+ between
(0.0574 - 4.21 ppm) and Ca+2 between (6 - 13.6 ppm) for all the samples were within the permissible
level of WHO (200 ppm Na+
, 10 ppm K+
and 200ppm Ca2+).
From the study we found that all water samples were accepted for all purposes
