The ion concentrations were within the allowable WHO limits except two springs located within the center of the populated areas. The water of most of the springs is contaminated with fecal coliform and total coliform. The concentration of nitrate shows moderate values below the WHO limits. The springs in the study area show higher concentrations of heavy metals (Zn, Cd, Mn, As, Co, Cu, Ni, Pb, Al, Fe, and V) exceeding the permissible standards set by WHO (2007). Most springs in the study area are of water type (Ca-Mg-HCO3-). Piper’s classification ranges from normal earth alkaline water with prevailing bicarbonate and chloride in both seasons.
