Which is an urban nonpoint source pollution example?

• A. Urban NPS example
• B. Rural NPS example
• C. Point source pollution
• D. Carbon cycle

Answer: (A)

Urban nonpoint source pollution occurs when pollutants from many small, diffuse sources in a city are carried into water bodies by rainfall or runoff from streets, parking lots, lawns, and other impervious surfaces. This is different from point source pollution, which comes from a single, identifiable discharge like a pipe or outfall. The best choice directly describes a pollution example from an urban setting, so it matches the concept of urban nonpoint source pollution. The other options aren’t the correct fit: a rural NPS example is still nonpoint but not urban; point source pollution refers to a specific discharge via a pipe or channel; and the carbon cycle is a natural global process, not an example of pollution sources.
