Almost all the water tested from South African rivers, especially those running near informal setlements showed evidence of either sewage pollution (high E.coli, varied phosphate, sulphate and nitrate levels) or mining pollution (low pH values, high electrical conductivity, high sulphate values and Bacterial Content).
The solutions are there, but is anything actually DONE about it? Not to my knowledge. It seems like those in charge prefer to turn a blind eye. Or by the time somebody listens to those who can provide solutions, it might be too late.
Being unaware or unwilling; the result is the same.
Water conservation is our responsibility.
