Final answer:
Point source pollution originates from specific sources like pipes or smokestacks, while non-point source pollution comes from diffuse sources. The Clean Water Act and best management practices are policies addressing these types of pollution.
Step-by-step explanation:
Point source pollution refers to the pollution that comes from a specific, identifiable source, such as a pipe or a smokestack. An example of point source pollution is the discharge of untreated wastewater from a factory directly into a river. A current piece of legislation designed to control point source pollution is the Clean Water Act in the United States.
Non-point source pollution refers to the pollution that comes from diffuse sources, making it more challenging to identify and control. An example of non-point source pollution is runoff from agricultural fields that carries pesticides and fertilizers into nearby streams. A current policy to control non-point source pollution is the implementation of best management practices (BMPs) in farming practices.
