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

Introduction

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.
