Integration of a Dolomite Risk Management Programme in Local Governance in South Africa: Tlokwe City Council

Autor: Stephanus Johannes Pretorius, Abraham Stephanus Potgieter, Izak Jacobus Van Der Walt

Publikováno v: Journal of Environmental Protection. :1041-1049

Development on dolomite poses a risk to people and their assets living on it. Although development in the Tlokwe City Council (TCC) broadly took cognisance of the presence of dolomite, some parts of the township had been developed on dolomite. Theref

The significance of groundwater–stream interactions and fluctuating stream chemistry on waterborne uranium contamination of streams—a case study from a gold mining site in South Africa

Autor: Izak Jacobus van der Walt, Frank Winde

Publikováno v: Journal of Hydrology. 287:178-196

Through seepage, dissolved uranium and other heavy metals migrate from tailings deposits of gold mines via groundwater into adjacent fluvial systems. The extent of associated stream contamination is determined, inter alia, by the retardation of disso

Gold tailings as a source of waterborne uranium contamination of streams - the Koekemoerspruit (Klerksdorp goldfield, South Africa) as a case study - part II of III: dynamics of groundwater-stream interactions

Autor: Frank Winde, Izak Jacobus van der Walt

Publikováno v: Water SA; Vol 30, No 2 (2004); 227-232

Dissolved uranium (U) from the tailings deposits of various gold mines in South Africa has been found to migrate via seepage and groundwater into adjacent streams. The extent of the associated non-point pollution depends on the concentration of U in

Gold tailings as a source of waterborne uranium contamination of streams - the Koekemoerspruit (Klerksdorp goldfield, South Africa) as a case study - part I of III: uranium migration along the aqueous pathway

Autor: Peter Wade, Izak Jacobus van der Walt, Frank Winde

Publikováno v: Water SA; Vol 30, No 2 (2004); 219-225

Tailings deposits from gold and uranium (U) mining in the Witwatersrand basin often contain elevated levels of radioactive and chemo-toxic heavy metals. Through seepage, dissolved U and other metals migrate from tailings deposits via groundwater into

Gold tailings as a source of water-borne uranium contamination of streams - the Koekemoerspruit (South Africa) as a case study - part III of III: fluctuations of stream chemistry and their impacts on uranium mobility

Autor: Frank Winde, Izak Jacobus van der Walt, Peter Wade

Publikováno v: Water SA; Vol 30, No 2 (2004); 233-239

Once dissolved uranium (U) from tailings deposits enters adjacent streams, subsequent downstream transport is affected by the rate at which U is immobilised in sediments, thereby lowering its concentration in stream water. For aqueous phases immobili
