A detail understanding of the hydrogeochemical characteristics and groundwater quality is indispensable for the sustainable utilization of the groundwater sources. This is in line with sustainable development goal of United Nation. The following parameters were analyzed using APHA, 2012 standard: pH, Ec, total dissolved solid (TDS,) total hardness (TH), magnesium (Mg2+), sulphate (SO4 2¯), chloride (Cl¯), bicarbonate (HCO3¯), carbonate (CO3 2¯), nitrate (NO3¯), potassium (K+), sodium (Na2+)and calcium (Ca2+). Findings revealed that pH value reveals that groundwater is acidic. Bivariate plots showed that groundwater quality is influenced by number of factors. Hydrogeochemical assessment of groundwater samples was based on the following model:End-member, Parson’s and Diamond field plots. Results from these plots revealed that silicate and carbonate weathering are the major factors that control groundwater quality and that groundwater samples were of different water type namely, Ca–Mg–SO4, Ca–Mg–Cl, Na–SO4 water type and high Ca+Mg & SO4+Cl respectively. It was observed that 99 % of groundwater within the study area fell within fresh water category and groundwater is influenced by various factors.
