Impact and risk assessment of chromium contaminated groundwater sites in saturated and unsaturated zones
(University of the Free State, 2011)English: A key challenge for chromium related activities, such as in ferrochromium industries, is the disposal of waste containing chromium slag or dust with hexavalent chromium (Cr(VI)). Various investigations have shown ... -
The impacts of fertilizer manufacturing on groundwater in South Africa
(University of the Free State, 2010-11)English: As a result of the fertilizer industry’s rapid growth, and the increasing global awareness concerning environmental issues, fertilizer production facilities have come under growing pressure to comply with ever ... -
The influence of anthropogenic nitrate on groundwater quality in the Thaba Nchu area
(University of the Free State, 2012-11)Enrichment of nitrate in groundwater is a worldwide phenomenon, mostly resulting from anthropogenic activities in densely populated areas. The objective of this study was to analyse the groundwater quality in Thaba Nchu ... -
The influence of flooding on underground coal mines
(University of the Free State, 2011-11)English: The purpose of the study is to investigate the influence of flooding on underground coal mines. Two case studies were investigated the shallow underground Klibarchan coal mine and the deep underground Usutu mine. ... -
The influence of the irrigation on groundwater at the Vaalharts Irrigation Scheme
(University of the Free State, 2009-11-20)English: Vaalharts Irrigation Scheme is not only the largest in the country it is known as “The Food Basket”. In 1875, Mr Ford, a Government Surveyor got the idea that the Vaalharts area has irrigation scheme possibilities ... -

Investigating the possibility of targeting major dolerite intrusives to supplement municipal water supply in Bloemfontein: a geophysical approach
(University of the Free State, 2017-02)The city of Bloemfontein is currently relying on surface water sources for its potable water supply. However, Bloemfontein is located in a semi-arid area, which means that the surface water resources are unreliable and ... -
Investigation into the groundwater interaction between a deep coal mine and a deeper lying gold mine
(University of the Free State, 2010-11)After the closure of mines, it is expected that water in the mined-out areas will flow along preferred pathways and accumulate in lower-lying areas (Grobbelaar, 2001). Over time, these man-made voids will fill up with ... -
An investigation into the temporal and spatial mobility of leachate production in a fly-ash dam

The investigation of nitrate contamination in the ground water of a chrome mine in the Kroondal area, South Africa
(University of the Free State, 2013-01)Although naturally occurring in groundwater, nitrate presence is generally attributed and regarded as a contaminant. Elevated nitrate levels pose a threat once converted to nitrite, causing methaemoglobinaemia. This ... -
Investigation of the groundwater hydrogeochemistry chracteristics in Beaufort West, South Africa
(University of the Free State, 2017-01)English: This study was conducted to investigate hydrogeochemical processes controlling the evolution of groundwater chemistry and their influence on water quality in the Beaufort West town. Beaufort West is located in a ... -
Managing the impact of irrigation on the Tosca-Molopo groundwater resource
(University of the Free State, 2005-05)From 1990 to 2000 rapid development of irrigation from groundwater resources in dolomite aquifers took place in the Tosca Molopo area. This abstraction lead to water levels declining 10 to 20m regionally and up to 60m ... -
Manual on pumping test analysis in fractured rock aquifers
(University of the Free State, 2000-11)English: With the depletion of surface water resources in South Africa the utilisation of groundwater as the only potable water resource for communities in some rural areas is quickly becoming a reality. Failure of this ... -
