Thesis (MTech (Biomedical Technology))--Cape Peninsula University of Technology, 2012. / In many developed countries worldwide the provision of safe, clean water is an expected
commodity. In South Africa however, as in most developing countries, the access and
supply of water safe for human consumption is challenged or complicated by pollution and
more recently water availability. Point-source pollutants in surface- and groundwater are
normally the most concentrated closest to the pollutant source (such as the end of a pipe or
an underground injection system). Examples of point-source pollution are commercial and
industrial businesses, that often discharge waste such as solvents and heavy metals from
their operations. In contrast, non-point-source pollution occurs due to runoff moving across
or through the ground and absorbing and accumulating pollutants which eventually end up in
streams, rivers and dams. The lack of waste removal and adequate sanitation facilities
results in the disposal of faecal matter and sewage into storm water drains which flow directly
into the river systems contributing to the incidence of diseases such as gastroenteritis,
diarrhoea and chronic lung ailments, caused by waterborne pathogenic bacteria, viruses and
fungi.
