Abstract:
Drinking water in Gedarif State is directly obtained from, berholes, hand pumps, hand dug wells, rivers, creeks, dams, hafirs and Khors. This study was aiming to measure the concentrations of some macro and trace minerals in surface and ground drinking water sources. Fourty (40) drinking water samples were analyzed by Atomic Absorption. The results were statistically analyzed. Surface water showed mineral means as, Ca (106.48 mg/l), Mg (27.05 mg/l), Na (7.59 mg/l), K (0.50 mg/l), Mn (0.0303 mg/l), Fe (3.7198 mg/l), Ni (0.0604 mg/l), Cu (0.0522 mg/l), Zn (0.0115 mg/l) and Cd (0.0164 mg/l). On the other hand Ground water mineral means were Ca (152.52 mg/l), Mg (76.25 mg/l), Na (11.86 mg/l), K (0.67 mg/l), Mn (0.016mg/l), Fe (0.071mg/l), Ni (0.061mg/l), Cu (0.042 mg/l), Zn (0.0099 mg/l) and Cd (0.010 mg/l). Similar concentrations were shown by Pb in both surface and ground water samples as (0.07mg/L). Some trace minerals showed relatively high concentrations in surface than ground water as, Cd (0.1 mg/l), Cu (0.092mg/l), Fe (21.17mg/l) and Mn (0.037mg/l), whereas ground water showed higher concentrations of Ni (0.109 mg/l) and Zn (0.046 mg/l).
