The present work was conducted to assess the physico-chemical parameters of Tsada Agam River found in Mekelle, Tigray, Ethiopia and determine its suitability for domestic and irrigation purposes. Water samples were collected monthly for two consecutive months (February to March, 2013) at four sampling sites and analyzed for various physico-chemical parameters. The study indicated that the mean value of studied parameters, except electrical conductivity, total dissolved solids, turbidity, total alkalinity, calcium ion, sulphate ion, and total phosphorus of the river water samples were within the permissible limit of WHO for drinking water. The findings also showed the mean value of studied parameters, except sulphate ion concentration, were within the permissible limit of FAO for irrigation water. Therefore, the river water was found to be unfit for human consumption and was found to be safe and utilizable for irrigation purposes. If the quality management was properly maintained, the Tsaeda Agam River water could be utilized for a wide range of applications such as drinking and irrigation.
