Final answer:
Point source pollution is the specific source of nutrient pollution that can be identified, such as a factory or wastewater treatment plant.
Step-by-step explanation:
The specific source of nutrient pollution that can be identified, such as a factory or wastewater treatment plant, is known as Point Source Pollution. Point source pollution refers to contaminants entering a waterway or water body through a single site.
Examples of point sources of pollution include animal factory farms, pipes from factories or sewage treatment plants, and combined sewer systems.
On the other hand, nonpoint source pollution refers to contamination that does not come from a single point source, but rather from a buildup of small amounts of contaminants that collect from a large area.
