Study Notes
Point Source Pollution
- Defined as pollution from a single, identifiable source.
- Common examples include leaking septic tank systems.
- Leaking storage lagoons contain polluted waste, contributing to point source pollution.
- Unlined landfills release hazardous materials into the environment.
- Underground storage tanks that leak contain harmful chemicals or fuels like gasoline.
- Active and abandoned mines often release polluted water.
- Industries discharge water which may contain pollutants.
- Waste-water treatment plants, public and industrial, can also be sources of point pollution.
Nonpoint Source Pollution
- Characterized by diffuse sources of pollution that are not easily traced.
- Chemicals such as salt and other de-icing agents are added to road surfaces.
- Water runoff from urban and suburban areas can carry oil, gasoline, animal waste, and trash.
- Pesticides, herbicides, and fertilizers applied to lawns, golf courses, and farms contribute significantly.
- Livestock feedlots can lead to pollution from feces and agricultural chemicals.
- Precipitation can pick up air pollutants, leading to contaminated runoff.
- Soil runoff from farming and construction activities carries sediments and pollutants.
- Personal watercraft can also introduce oil and gasoline into waterways through nonpoint source pollution.
