  2. 6. Wetlands as a means to reduce the environmental impact of mine drainage waters

    Author : Åsa Sjöblom; Bert Allard; Karsten Håkansson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lakvatten; våtmarker; vattenrening; miljö; Water in nature and society; Vatten i natur och samhälle;

    Abstract : In many mining regions of the world, pollution of surface water and groundwater by drainage water originating from mines aiming waste poses either a serious threat to the environment, or a severe environmental problem. During the last two and a half decades, treatment of mine drainage water in constructed and natural wetlands has emerged as an alternative to more conventional methods to handle the problem.

    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
