Water scarcity, along with access to clean water, seem to be a growing issue in Africa due to environmental issues (such as pollution) the continent is still facing. This topic is seen as one of the difficult and most daunting subjects as it is founded on many idiosyncratic principles and different perspectives. Very often, water and waste water projects are expensive, as they are multi-disciplinary projects involving, in most cases; civil, environmental and mechanical engineering. 2.1 Name and discuss two major categories of water pollution and give impacts associated with these two major pollutants (1 component/pollutant for category 1,1 component for category 2 and a common impact for both categories). (10) 2.2 A very small settlement, somewhere in Mpumalanga, has a shortage of water supply; in fact, in most cases there is no water. The community uses a small lake and a borehole (sometimes) as their source of water. a) Between the two sources, which one would you discourage the community to continue using and why? (5) b) Which disinfection method would you encourage the community to follow in order to have the water safe for human consumption and why? 2.3 Discuss different issues concerning water quality (for consumption) in South Africa, your discussion should be centred around the following factors: environmental (groundwater quality), social and economic (how the government and people play role in this issue)
