| Overcrowding in Greater Johannesburg causes exploitation of the land beyond its capacity, which leads to land pollution. This exceeds the capacity of sewer systems and landfill sites. Sewage problems mainly exist in large parts of Alexandra and Soweto townships. To the south and southwest of Johannesburg, dust pollution from mine dumps are the main sources of environmental degradation, while the CBD experiences continuous overflowing of sewers, especially in Hillbrow, Newtown and Jeppestown. All these activities reduce the quality of the surface environment. The main sources of land pollution were identified as informal settlements, waste disposal sites, mining activities and activities in CBD’s. |
