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 ... -

Quantification of the impacts of a domestic waste site on a Karoo aquifer
(University of the Free State, 2008-05)Waste generation is a widespread phenomenon around the world, of which the majority is disposed by landfilling. In landfills, waste constitutes an integral part of the hydrological system, and thus poses a threat to ... -
A quantitative approach in mine water balances and strategic management
(University of the Free State, 2014-04)English: The vital role of water within the mining industry, both as an asset which generates value as well as a shared natural resource requiring responsible stewardship, have long been recognised. Due to extreme climate ... -
Reactive transport modelling of fertilizer waste in a dual porosity aquifer
(University of the Free State, 2011-11-16)English: The fertilizer production facility had a negative impact on the soil, groundwater and surface water environment due to the handling / storage and production activities at the site. Observations and numerical ... -
Reconceptualization of the extended groundwater regime of the Vaalputs radioactive waste site
(University of the Free State, 2015-08)Vaalputs Radioactive Waste Site is the only nuclear waste facility in South Africa that stores Low- and Intermediate Level Radioactive Waste. Disposal of waste is carried out under the authorization granted by the National ... -
