Which of the following is an example of point-source water pollution?
-
A.
Runoff from agricultural land
-
B.
Animal faeces from dogs and birds
-
C.
Wastewater pipe from a factory
-
D.
Pollutants from car parks
Correct Answer:
C. Wastewater pipe from a factory
Explanation:
The correct answer is a wastewater pipe from a factory. Point-source pollution is defined as contamination originating from a single, identifiable, and discrete location. Common examples include discharge pipes, ditches, or tunnels from specific industrial facilities or sewage treatment plants. In contrast, pollutants like agricultural runoff, animal waste from scattered wildlife, and debris from parking lots are considered nonpoint-source pollution because they come from diffuse areas and are typically carried into water bodies by rainfall or snowmelt.
