Abstract
Geostatistics and Spatial Analysis of Groundwater Hydrochemistry near Leliefontein in the Northern Cape, South Africa
Highlights
The groundwater resources are an intrinsic part of the water resources of South Africa
The groundwater quality assessment is an essential step towards groundwater management, utilisation and pollution control
Leliefontein is dominated by NaCl groundwater type, and from the results, 94.7% indicated the NaCl type, 2.6% CaCl type and 2.6% NaHCO3 type
Summary
The groundwater resources are an intrinsic part of the water resources of South Africa. High fluoride concentration (0.14 to 10.18 mg/l with mean: 2.48) was observed, with 71% of the groundwater samples exceeding the SANS241 recommended limits. The salinity of groundwater usually is a result of increasing ion concentration, recharge water evaporation, and geological formations.
