Ethics Clerance number is 220164711/10/2021 

The study was conducted in the Breede Water Management Area in the Western Cape province in South Africa. The aim was to assess the status of groundwater quality, the suitability of the water for domestic and irrigation purposes and factors contributing to the groundwater chemistry. Twelve (12) monitoring boreholes were selected for sample collection. The samples were analysed for major ions such as potassium (K+), magnesium (Mg2+), sodium (Na+), calcium (Ca2+), chloride (Cl-), sulfate (SO42-), bicarbonate (HCO3-), nitrate (NO3-), fluoride (F-) and physical variables like pH, electrical conductivity (EC), total dissolved solids (TDS) and temperature.
