摘要：This study investigated the geochemical and geological characteristics of the Homase mineral deposit(s) environment in Ghana. The aim of the study was to identify and characterize, the signatures influencing the composition of natural drainges in the area. Streams, hand-dugout wells and a borehole samples in the catchment area were analysed for water quality parameters including metals, major and minor elements. Mineralogical composition of mineralized and un-mineralized rocks carried out by other workers in the area was used to ascertain the possible sources of the metals etc. Local geology and sulphide mineralisation with arsenopyrite and pyrite being the dominant sulphide minerals influence water variation. Analytical results using standard methods study, shows that streams are being impacted by iron and arsenic in the ranges 0.02 to 3.56 mg/L and 0.02 to 1.30 mg/L, respectively. Also ranges for the above metals in hand-dugout wells are 0.03 to 0.48 mg/L and 0.24 to 1.32 mg/L, respectively. This geochemical information suggests the mineral deposit(s) is relatively benign to the Homase environment.
