The issue of acid mine water in the Witwatersrand area and surrounds has largely dropped off the radar, but it most certainly should not have, if these photos are anything to go by.
Environmentalists have been warning the government about the water being caught in unused mines filtering through into the ground water and eventually into our rivers and dams for years already, and although decisions were made about the treatment of the water, work is moving along slowly.
In separate situations, existing mines can sometimes also be to blame for water pollution if there systems are not working perfectly.
In this series of photos, one can see the impact of leaked mine water into a natural water catchment area. Thousands of fish suffocated and died after polluted mine water entered a dam in Middelburg.
Sonika Oosthuizen, a member of the local SPCA in the area, was on-hand to give some of the fish a merciful death.
