The groundwater quality in the Agona East District has been evaluated for drinking and irrigation uses. Fourteen boreholes from the district were sampled and analyzed to study the groundwater hydro chemical characterization. The objective was to characterized groundwater chemistry on a small scale to understand the processes that influence the hydro chemistry of the groundwater, the possible source of contaminates and the groundwater suitability for drinking and agricultural purposes. Previous studies have reported on the hydro chemical characterization of groundwater on a large scale. However, the detail work with regard to groundwater characterization as well as the quality of the groundwater in the locality is lacking. The study involves taken of groundwater samples, analysis of the samples in the laboratory and analysis of the data generated. The order of the cation in the water samples is Na+> Ca2+> Mg2+ > K+ while that of the anions is HCO3-> SO42-> Cl-> NO3-. The study revealed that the major groundwater types in the study area are CaMgCHO3, mixed water and NaCl in decreasing order. The study identified carbonates weathering, silicate weathering, ion exchange together with improper waste disposal as factors influencing the hydrochemistry of the area. The high correlation between groundwater parameters indicates that similar processes influence the concentrations of the parameters. The groundwater is considered suitable for drinking and domestic purposes because almost all the parameters such as Na+, K+, HCO3-, Cl-are within the permissible limits prescribed by WHO (2012), and calculation of WQI shows that it is good for drinking purpose. However, low pH is the health-based concern observed in the groundwater use for drinking and domestic purposes. The groundwater is generally good for irrigation; however, the high sodium percent (%Na > 60%), high Kelly Index (KI > 1) and High Magnesium Ratio (MR > 50%) in some samples are the concern observed for the groundwater use for irrigation.
