Hydrogeological studies on the Tarkwa gold mining district, Ghana
Abstract The physical hydrogeology of the Tarkwa area has been evaluated with a view to improving the understanding of its groundwater characteristics. It has been inferred that aquifers in the Tarkwa area possess dual and variable porosity and heterogeneous permeability with predominantly limited storage properties. Both soil infiltration and pumping tests have shown that the Banket Series has the best hydraulic features, but the Banket rocks are host rocks for gold. The effect of mining on the groundwater regime is discussed, comparing groundwater recharge estimates obtained using the water balance method (299±72 mm $ year^{−1} $) and the stream hydrograph method (192±30 mm $ year^{−1} $).
