Types of sources of water pollutants
Point Sources
Non-Point Sources
5 general sources of water pollutants
Domestic Sewage
Industrial Wastewater
Agricultural Run-off
Stormwater Run-off
Naturally-Occurring sources
defined as wastewater discharged from residential commercial, institutional, recreational and industrial facilities where wastes are generated through the use of dining facilities, shower rooms and toilets.
Domestic Sewage
principal example of a point source
Industrial Wastewater
discharged by industries after water has been utilized in production processes.
Industrial Wastewater
Examples of non-point sources.
Agricultural Run-off
wastewater from farms which often carries fecal materials, soil particles, fertilizers (phosphates and nitrates), and pesticides.
Agricultural Run-off
results from rainfall and may cause turbidity and contamination of receiving water bodies.
Stormwater Run-off
Surface Water Quality Issues and Concerns
Untreated Domestic Sewage
Industrial Wastewater Pollution
Threats from non-point pollution Sources
Inefficient Solid Waste Management
a leading contributor to water pollution.
Untreated Domestic Sewage
Those contribute extraneous materials into watercourses from an extensively wide area thus making it much harder to control.
Non-point sources
has a major contribution to water quality deterioration.
