A draft reply from the South African Minister of Water and Environmental Affairs regarding fish kills in the Blaaubankspruit in January 2011, attributing the event to sewage effluent rather than acid mine drainage.

• A fish kill incident involving large carp (Cyprinus sp.) was reported on 13 January 2011 in a private dam on the farm Sterkfontein in the Krugersdorp area, which is fed by the Blaauwbank Spruit.
• Analysis of water samples from the dam on 13 January 2011 revealed elevated levels of ammonia and nitrates, which deplete oxygen levels and are detrimental to fish health. These levels are linked to sub-standard discharge from the Percy Stewart Wastewater Treatment Works, which was undergoing upgrades, rather than acid mine drainage.
