Arsenic occurrence in the groundwater of South Africa

20241 citationOpen accessUniversity of the Witwatersrand

Abstract

Arsenic (As) in groundwater has variable concentration, which is controlled by the mineralization of crystalline rocks. Consequently, its concentration in the groundwater reaches up to 253 μg/L (Namaqualand), 6150 μg/L (west of Johannesburg), about 500 μg/L in the Karoo aquifers. Acid mine drainage is also found to be important source for As and other toxic metals in the environment.
