Geological and Hydrochemical investigation of Okposi and Uburu Saline spring Areas of Ohaozara and Environs of Ebonyi State has been carried out. The study area is underlain by shales which vary from light to dark grey in colour, fine grained sandstone and mudstone which belong to the Asu River Group and the Ezeaku Shale, (Albian and Turonian respectively). Results of hydrochemical analysis revealed that Ca2+, Mg2+, Fe2+, Na+ (cations), Cl- , SO42-, NO3-, HCO3- (anions) and Br- , Mn2+ , F- , I-, Al3+, Mo2+, Co2+, Hg2+, Cr3+, Ni2+, Cd2+, Ag+ and Mn2+ are the main geochemical constituents. Water facie evolution shows three water types namely, the calcium bicarbonate facies in the northern parts and sodium chloride facies with sodium/potassium bicarbonate facies in the southern parts. Groundwater flow pattern reveals predominance of recharge and discharge at the northern and southern parts respectively.
