In order to investigate the physico-chemical quality, 54 water samples were collected from Argo city, northern Sudan, during the period of May to Sep¬tember 2017. The parameters include pH, Turbidity, Total Dissolve Solids (TDS), Hardness and Electrical Conductivity (EC), anions (Chloride, Bicar¬bonate, Sulphate), and cations Calcium, Nitrate, Fluoride, Iron and compared with (WHO) and (SSMO) standards. The results of the study showed that pH values were between 6.6 to 7.2, hence, all samples are slightly alkaline be¬cause the phenolphthalein alkalinity was found equal to zero for all samples alkalinity of samples is caused by the presence of hydrogen carbonate only and no carbonate present, the Turbidity values for all samples were high than the normal limit prescribed by (WHO). The results of the (EC-TDS -HCO'3) values were found within the permissible values of (WHO) and (SSMO). The concentrations of Iron, Sulphate, Chloride, Nitrate, and Calcium are less than (SSMO) and (WHO). Fluoride concentrations were in all area of the study within the range of (WHO) and (SSMO).
