Groundwater development in the Central Region of Ghana is being hindered by poor water quality. High salinity waters have been reported in the area (Armah, 2000). Significant numbers of boreholes have been abandoned because of high salinity. Since the study area is close to the coast, various hypotheses have been advanced for the high salinity of the groundwaters. These include seawater intrusion, marine aerosols, soluble salts in the soil zone and sluggish movement in the groundwater flow system. Even though some investigations have been carried out in the area, the source of the high salinity waters is not well known. In this research, major ions in groundwater and stable isotopes (18O and 2H) are being used to understand the hydrogeochemical processes controlling the overall chemistry of groundwater in the area.
