Author:Greben, HDate:Aug 2007Acid mine drainage (AMD) is a common result of mining activities caused by bacterial oxidation of sulphide minerals (pyrite) that results in sulphate rich waste water. AMD can be treated biologically in the presence of sulphate reducing ...Read more
Author:Godfrey, Linda KDate:Aug 2007Research into integrated waste management is undertaken in view of the impact of increasing populations and a strong national focus on industrial, agricultural and urban growth that is likely to result in the increase of human induced pressures ...Read more
Author:Steyn, MaronelDate:Aug 2007Lack of access to proper water, improved sanitation and hygiene, is the main risk factor attributable to diarrhoeal-related disease in the country. Of the 48 million people in South Africa, approximately 3.3 million people still lack access ...Read more
Author:Greben, HDate:Aug 2007The biological sulphate removal technology requires carbon and energy sources to reduce sulphate to sulphide. Plant biomass, e.g. cut grass, is a sustainable source of energy when cellulose is utilised in the anaerobic degradation to produce ...Read more
Author:Turton, ADate:Aug 2007All mines have a finite lifespan. In the past South African mines were often simply abandoned when the ore was finished, with little consideration for post-mining environmental conditions. The consequences of this approach, both in terms of ...Read more

Author:Colvin, CDate:Aug 2007Aquifer dependent ecosystems (ADEs) rely on groundwater in aquifers. They may occur where groundwater discharges from the aquifer to the surface environment, such as springs, wetlands and seeps, or where aquifers contribute to the base flow ...Read more
Author:Genthe, BettinaDate:Aug 2007This study demonstrates that copper is effective at reducing bacterial numbers at concentrations that are typically permitted in drinking water (depending on the guideline of the country). It has however highlighted the need for a better ...Read more
Author:Roux, DDate:Aug 2007The Fish to Tsitsikamma Water Management Area is one of 19 water management areas
in South Africa and is situated mainly in the Eastern Cape Province. The systematic conservation plan used quaternary catchments for planning units and rivers ...Read more
Author:Genthe, BettinaDate:Aug 2007Environmental health risk assessment deals with risks associated with manmade and natural environmental hazards. Environmental health risk assessment provides a means of estimating the probability of adverse health effects associated with ...Read more
Author:Claassen, MariusDate:Aug 2007Socio-economic development depends on the reliable supply of water for industrial, mining, agricultural, potable and recreational purposes. These activities also generate waste products that are often discharged to surface water. South Africa’s ...Read more
Author:Colvin, CDate:Aug 2007Resistivity is a non-invasive geophysical method that can be used to provide additional information on the subsurface. This can then lead to cost-effective answers to geological questions. The bulk resistivity of different subsurface units ...Read more
