    The inhabitants of the study area have been faced with a scarcity of clean water and sometimes suffer outbreaks of epidemics; the studied artesian springs are their major alternative source of water. Ten artesian springs were assessed using magnetic methods and hydrochemical analysis. Total magnetic intensity (TMI) data were processed to obtain the lineament distribution responsible for groundwater flow. Physicochemical parameters analyzed include pH, total hardness, and electrical conductivity. In addition, chemical parameters such as chloride and iron were analyzed. Results showed a magnetic anomaly range of 79.1 - 132.91 nT. There is a series of lineaments, depicting fractures with a high concentration in the northern part. Three of the springs fall on the multiple fracture locations, around the high magnetic anomaly, indicating a highly promising location. The range of parameters is as follows: pH: 5.91 - 7.09, electrical conductivity: 30 - 450 µs/cm, total hardness: 20 - 136 mg/L, chloride: 10.01 - 56.0 mg/L. All these are within the World Water Quality Standard tolerable values, except the iron content, which is above 1mg/l in all the locations, which falls above the permissible standards of 0.3. This could be associated with the contamination from open defecation practiced in the area.
