Water is the most important resource which is essential for sustaining all life forms, since without it, life cannot exist and industry cannot operate. However, increasing concern is being expressed at the rate of degradation of this important resource, which, to a large extent, is due to the advent of industrialization and urbanization. The major causes for this concern is that the progress towards urbanization is often made without due regard to the consequences. Furthermore, the effect of man’s social and industrial activities can be seen in the extent to which river water quality changes as a river flows from its source to the sea. Water which is returned to the river as effluent is rarely the same quality and is normally contaminated with some form of pollution. South Africa is a country where water is a scarce and precious resource. Coupled with low rainfall and a high evaporation rate, is the lack of basic services which are concentrated in areas where demands of the most vital resource is ever increasing. In addition, urbanization is experienced at a phenomenal rate, much of which is in the form of informal settlements. These constitute overcrowded "shacks" with no running water and sanitation facilities. Furthermore, imbalances in the ecosystem are created when humans strive to undertake the economic demands of the world resulting in poor environmental management practices and unhealthy living conditions. These communities lack basic services and as a result, resort to environmental degradation where the removal of vegetative cover, waste disposal and water pollution are evident. Furthermore, many of the informal settlements are situated in close proximity to water source, especially rivers. In the absence of sanitation, these communities make use of shallow pit latrines, river banks, etc. The potential for pollution is therefore very high in these communities. This provided the researcher with theThe purpose of the study was to determine the influence of the Umlazi informal community, L-SECTION on the water quality of the Umlaas Riv
