An investigation has been started by the authorities in Johannesburg, the commercial center of South Africa, when a resident discovered blue water coming from her tap.
The resident posted a photo and a video of her terrifying incident on social media on Monday.
According to local sources, a Johannesburg Water spokeswoman claimed that although samples had been gathered for testing, the company believes the water was tainted by copper in the structure.
Puleng Mopeli is cited as adding that the results are anticipated in 24 hours following the testing of the samples.
