A pollution source located at a specific point, such as a pipe or outlet, is called what?

• A. Nonpoint Source
• B. Diffuse Source
• C. Remote Source
• D. Point Source

Answer: (D)

Think of pollution sources in terms of how easily you can point to the exact spot where pollution enters the environment. A discharge from a single pipe or outlet is a point source because there is one identifiable location. You can trace the pollutant directly to that outlet and measure its contribution. Nonpoint sources, by contrast, come from many places across a watershed and are brought together by runoff, making them diffuse and hard to pinpoint to one origin. The term remote source isn’t a standard category here, and diffuse source describes widespread contributions rather than a single discharge. So, a pollution source located at a specific point, like a pipe, is a point source.
