The objective of this work is to assess the groundwater around Edku lake for irrigation and know the effect of lake on the quality of the groundwater around it. So, groundwater samples were collected from different dimensions and directions from edku lake, and chemical properties of the collected groundwater were determined. The appropriateness of groundwater for irrigation use various parameters like pH, electric conductivity, sodium absorption ratio, and water quality index was assessed. The results of samples analysis showed that pH values ranged from 7.11 to 8.11, and electric conductivity values fluctuated between 2.01 and 3.54 ds/m. Moreover, the sodium adsorption ratio of the groundwater samples ranges between 0.87 and 13.91. While the water quality index showed all wells are very poor for irrigation without wells No.5 and 8 are poor for irrigation. This study shall help to analyze the quality of water and provide support to the decision makers for better water resource management.
