    Aug 16, 2015 The review of studies on arsenic in African waters shows that arsenic can be found in high concentrations in both surface water and groundwater. Arsenic concentrations in African groundwater range between 0.02 and 1760 μg L−1, whilst the level of arsenic in surface water is ranged up to 10,000 μg L−1. This high level of arsenic in surface water is related to mining operations ...
