Apond is located beside an open mine. mercury from the mine contaminates the river water. this is an example of:
- single pollution
-multiple pollution
-point source pollution
-non-point source pollution

The correct answer is C. Point source pollution

Explanation:

Water contamination like the one that occurs in the case presented takes place as certain contaminant such as trash, chemicals or not natural substances are released into the water of lakes, rivers, oceans, etc. Additionally, this contamination can be classified as non-point source pollution in the cases where pollution originates from multiple sources or a source that cannot be clearly identified or point source pollution if the cause can be identified. This implies in the case presented in which water contamination clearly occurs due to the mine that releases mercury into the water this is an example of point source pollution as a source of the pollution is defined and identifiable.
