5. Treatment of arsenic contaminated drinking water from the sources around the gold mining areas of Geita and Mara, Tanzania : Removal efficiency of locally available materials, bauxite, gypsum and magnesite
Abstract : In recent years, high arsenic (As) levels of about 300 µg/L have been reported around the gold mining areas of Geita and Mara regions within the Lake Victoria basin (LVB) in Tanzania. During a sampling campaign at Geita and Mara, the groundwater and surface water samples revealed the presence of high As concentrations as well as Fe and sulfide. READ MORE
