Answer 1

Answer:

Point source pollution:

• Smoke from a factory

• Sewage

• Oil from a garage that  is released into water

Non-point source pollution:

• Smoke from cars

Explanation:

According to United States Environmental Protection Agency (EPA) regulations, point source pollution is a type of pollution in which contaminant is released into the environment from an easily identified source. In the examples given above, smoke from a factory, sewage, and oil effluents are coming from easily identifiable sources.

On the other hand, a non-point source of pollution is the release of contaminant in the environment through diffused or unidentifiable sources. In the examples given above, smoke from cars could be stated as non-point sources of pollution because vehicles are in a continously moving state.
