Dangerous Water Musa Nzimakwe went to visit his family in the rural area of KwaZulu-Natal. Musa has piped water in Durban where he lives. At his rural home, people drink the water from a stream running through the village. People also used the bushes near the stream as a toilet. After a few days, Musa became very ill with diarrhoea and had to go to the hospital. He had cholera, a disease caused by germs in water polluted with human waste. Musa was lucky, as people often die from cholera. The local municipality has now provided toilets, but they did not include an education programme to teach people how to prevent diseases such as diarrhoea and cholera. They also put in hand pumps to pump water from underground boreholes, but people still use water from the stream because they say it is too far to walk to the hand pumps. [Adapted from an article in EnviroTech, May 2004, taken from Water Wheel, Nov/ Dec 2003, Water Research Commission]. 6.1 Compare piped water to water from a stream. 6.1.1 Piped water: 6.1.2 Stream water: (2) 6.2 Explain why the water near Musa’s home is polluted.

What are the causes and effects of water pollution in Africa? Author: Matthew McClure Date published: 1 September 2021 What causes water pollution, and what is the effect of water pollution on at- risk communities and ecosystems in Africa? Water pollution in Africa is being caused by humans. There’s no denying it. The very species that is so dependent on safe and clean water, is the species that is causing freshwater sources to be polluted. But, what is water pollution? Broadly defined, water pollution is the process of foreign substances entering a water body (either above or below ground) and in the process causing the water to be unusable or toxic to the ecosystem in which it is located. The effects of water pollution are catastrophic. Plant and animal life suffers, and so do vulnerable people and communities. Hold your government to account and make sure that all Africans have access to clean, healthy water. Make no mistake, access to clean, healthy water is a fundamental human right. Clean water is essential to life, but it is a scarce resource in Africa. The causes of water pollution and its effects on people, flora and fauna, is currently one of the biggest environmental threats to Africa. Unfortunately, water pollution in Africa is on the rise.
