Verified step by step guidance1
Understand the definition of point source pollution: Point source pollution refers to contaminants that enter the environment from a single, identifiable source, such as a pipe, ditch, or smokestack.
Identify the characteristics of point source pollution: It is typically localized and can be traced back to a specific location or facility.
Examine the options provided: Air pollution from vehicles, runoff from agricultural fields, urban stormwater, and a factory discharge pipe.
Analyze each option: Vehicles, agricultural fields, and urban stormwater are examples of non-point source pollution because they originate from multiple, diffuse sources.
Recognize the correct answer: A factory discharge pipe is a point source of pollution because it is a single, identifiable source where pollutants are discharged directly into the environment.
