Abstract
The hydrogeochemical and isotopic evolution of groundwater in the Central Region of Ghana has been studied in order to examine how hydrogeochemical processes control the overall groundwater chemistry in the study area. Two major hydrochemical facies have been identified as the Na-Cl and NaHCO{sub 3} water types. The Na/Cl molar ratio indicates that silicate weathering is one of the major hydrogeochemical processes controlling groundwater water chemistry in the area. This is further confirmed by a plot of TDS against the Na/Na+Ca ratio. The Br/Cl ratio ranges from 0.00148 to 0.7087, suggesting minimal seawater intrusion in the area. Stable isotope values of the groundwater samples ({sup 18}O and {sup 2}H) are found around the global meteoric water line (GMWL), suggesting a direct infiltration of rainwater into the groundwater system. Elevated Cl- concentrations of the groundwater is probably due to sea spray and marine aerosols deposited on the top soil, though further studies are needed to determine the cause. (author)
