Question

Which of the following is an example of non-point source pollution?

A) sewage spill from a wastewater treatment plant
B.) Acid wastewater from a pickle factory
C.) Gasoline run-off from roads
D.) Oil from a leaking underground tank

Answer 1

The correct answer is:

C) Gasoline run-off from roads

Non-point source pollution refers to diffuse sources of pollution that are not easily traced to a single, identifiable source. Gasoline run-off from roads is an example of non-point source pollution as it originates from multiple sources (vehicles) and is carried by rainwater or runoff into water bodies. In contrast, options A, B, and D involve point sources with identifiable origins: a sewage spill from a wastewater treatment plant, acid wastewater from a pickle factory, and oil from a leaking underground tank, respectively.
