Abstract :

The current study was conducted to  evaluate physical and chemical parameters of water quality taken from some of ground wells  in Almanagil town, Gezira State, Sudan. The efforts, in this work, included a collection of different groundwater samples from Managil town. Many groundwater samples were collected from different wells distributed throughout the area of study. From all these groundwater samples, only eight samples were selected, to exclude repetition, and subjected to physico-chemical analysis. The physical characteristics including: conductivity (EC) of the collected samples were determined. The values of different chemical parameters as: pH, total dissolved salts (TDS) were measured according to the standard methods of analysis. In addition, the concentration of many anions (chloride, nitrite, nitrate) were determined. Results showed that EC between 440 -601 (ppm), GH 1000 (mg/L) all, NO³ and NO²  0.00 (mg/L) , Cl₂ range between  0.7-3.58 (mg/L) ,KH 120- 362.667 (mg/L) ,salts 18.0-20.0 % ,  pH has values ranged from 8.0 – 8.5 while the Total Dissolved Solids (TDS (mg/L)) between 6.67 – 12.0 (mg/L) whereas (TDS (ppm)) between524.33- 653.67 . The results revealed significant different at (P≤ 0.01) with exception of (NO³) value zero so (NO²) and GH (1000mg/L) were not significant at P> 0.05). The findings show validity of certain samples for human uses.
