A holistic hydrogeological environmental site risk assessment methodology for the fertilizer industry in South Africa
(University of the Free State, 2013-04)
English: There has been a definitive increase in environmental legislation over the past decade. These new environmental laws established principles such as duty of care and the polluter pay principle. Numerous companies ...
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 ...
A geohydrological assessment of arsenic as a contaminant in the Jagersfontein area and remediation options
(University of the Free State, 2012-12)
English: This thesis aims at geohydrologically assess arsenic in the Jagersfontein area and hence proposing remediation option. The field procedure carried out involved hydrocensus and sampling where samples were collected ...
Quantification of the impact of irrigation on the aquifer underlying the Vaalharts irrigation scheme
(University of the Free State, 2003-11)
Abstract not available
A groundwater-surface water interaction study of an alluvial channel aquifer
(University of the Free State, 2011-11)
The study describes the application complimentary geohydrologic tools to investigate the geohydrological properties of an alluvial channel aquifer and its interaction with the river surface water resources. Primary field ...
Estimation of representative transmissivities of heterogeneous aquifers
(University of the Free State, 2011-11)
English: The study describes the effect of calculating a generalised mean transmissivity or hydraulic conductivity value for a region or aquifer system as it pertains to South Africa. Resource determination of an area is ...
Quantification and modelling of heterogeneities in aquifers
(University of the Free State, 2017-01)
English: The future of modelling of heterogeneity in aquifers is definitively in the designing of
new in situ testing (hydraulic and mass transport) procedures with new corresponding
mathematical models. New trends in ...
Aquifer test interpretation with special emphasis on the drawdown evaluation for wells within fracture networks smaller than the representative elementary volume (rev)
(University of the Free State, 2002-05)
Fractured aquifers are characterized by the fact that most of the water flows along
fractures, faults, open bedding planes, or other geological features. These features are
embedded in a matrix that has either porous ...
Risk based decision tool for managing and protecting groundwater resources
(University of the Free State, 2001-11)
English: The limited number of water resources in South Africa has resulted in increased
emphasis being placed on groundwater. Groundwater supply of acceptable quality
and quantity is a very important factor in the ...
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 ...
