Point and Non-Point Source Pollution
Name: ______Period: _____ Date: ______Essential Question: How do I help prevent being a part of non-point pollution source pollution?
Pollution refers to excessive amounts of waste, much of which contains harmful toxins that are released into the environment- air, water, and soil. Pollution is usually caused by people; more specifically it is caused by the waste produced by the cars we drive, the factories that make the things we buy, the power plants that produce the gas and electricity we use, and even the farms that grow the food we eat.
Two types of pollution sources are Point source pollution and Non-point source pollution.
1. Point source pollution: pollutants from a specific, identifiable source, such as pipe, tank, pit, ditch or channel to a body of water. The bulk of point source pollution comes from wastewater discharge from power plants or large industrial plants. http://www.cartoonstock.com/directory/i/industrial_factory.asp
2. Nonpoint source pollution: pollutants from a diffuse ( spread wide ) source rather than one specific source. Usually nonpoint source pollution is transported by storm water run offs from large land areas which may contaminate the surface and ground water over a large area. http://baxtercomics.com/?page_id=139
