Two weeks later, the source of t he water pol l ut i on at t he Lusushwana River remains unknown wit h t he S wazil a nd Environment Authority (SEA) still awaiting laboratory test results to determine what could have made it black.
A fortnight ago, the Sunday Observer reported the water pollution which has turned the river black. The SEA took samples of the water for testing.
SEA Public Relations Officer Belusile Mhlanga said they were awaiting laboratory results as the samples were submitted to an independent entity for testing.
She has, however, reiterated warnings that the public should refrain from using the water for domestic purposes and avoid consuming its fish.
The absence of tangible evidence about the source of the pollution has given rise to speculation as guards situated along the river stated that they suspected that the pollution originated from a malfunctioning effluent plant situated along the place where water was visibly black.
This they say may have resulted from shortage of electricity two weeks ago. Notably, there are two effluent plants within the area.
On the other hand, a source within t he S wazil a nd Water Services Corporation (SWSC) alleged that some companies within the industrial site do not have effluent plants as they dump their waste in the river, bypassing the one from SWSC as they try to minimise costs.
The source suggested that SEA should carry out inspections in the area which would expose such companies.
Mhlanga, however, said SEA was not aware of such companies but said those
who knew these companies should report them to the authority.
"Precautions should also be exercised for any other uses until SEA determines the nature of pollution from the results of the water analysis which we are still awaiting from the independent laboratory," warned Mhlanga. The polluted river supplies water to families and entities within its corridor, including Nhlambeni, Sidvokodvo and Matsapha.
