Abstract:
This work was conducted to determine the suitability of some surface and ground water sources for human consumption from quality control assessment sight of view. Fourteen surface water and twenty six ground water samples were collected from different areas of Gedarif State (Sudan). Six samples were obtained from gold mining areas. pH value, EC, TDS, TH, DO, ?Cl?^- , ?CO?_3^(2-) and ?HCO?_3^- were measured. The obtained results were statistically analyzed. The mean values of pH and DO in surface water were found to be lower than that, of ground water samples. Two ground water samples showed high pH values as (8.2 and 8.9). The highest DO was shown by one surface water sample as (5.57 ppm). The mean values of TDS, EC and TH were lower in surface water than ground water. Two ground water sources showed TDS as (1042.00 and 1657.60 ppm) and EC as (1515.00 and 2590.00 µs/cm), which, exceeds the permissible WHO guidelines. High TH was shown by two ground water sources (1580 ppm). The highest, ?Cl?^-,?HCO?_3^-, and ?CO?_3^(2-) concentrations were shown by ground water sources as (343.90, 536.80 and 36.00ppm) respectively. Surface water sources showed lower mean concentrations of ?Cl?^- and ?HCO?_3^-, than ground water ones, whereas, the mean ?CO?_3^(2-)content was higher in surface water. All the water sources of the analyzed samples may be suitable for human consumption, domestic use, animal intake, and irrigation purposes.
