constituents of groundwater and surface water in the study area. According to the diagram, sodium is the dominant and calcium is the least in hand dug wells tapping Upper aquifer while in boreholes tapping Middle and Lower aquifer, magnesium is the dominant element and the chloride is least in the plot as presented below in Figure 8a and 8b.
