Rainwater pouring from an eroded bank into a river is considered a non-point source of pollution. This is because the pollution does not originate from a single, identifiable source but rather from a diffuse area where rainfall washes away soil and contaminants into the waterway. Point sources, on the other hand, refer to specific, identifiable locations such as pipes or discharge outlets.
Nonpoint-source pollution
Nonpoint source pollution is difficult to regulate, because its source is difficult to track.

Yes, surface runoff is an example of nonpoint source pollution. It occurs when rainwater or snowmelt flows over the ground, picking up pollutants such as fertilizers, pesticides, and chemicals, and carries them into water bodies like rivers and lakes. This type of pollution comes from diffuse sources across a wide area, making it challenging to pinpoint a single source.

If the only source of the gasoline is that one gas station, then it is point pollution. Nonpoint pollution sources can include leaking vehicles, but a large spill is more than likely from the gasoline station. .
Nonpoint source pollution generally results from land runoff, drainage, or seepage, that is not through a pipe, ditch, or channel, et cetera, from which pollutants are discharged.
Nonpoint-source pollution is contamination that originates from diffuse sources, such as runoff from roads, agricultural fields, and urban areas. It is a major contributor to water pollution and can be challenging to control because it comes from widespread and varied sources. Examples include pesticides, fertilizers, and sediment washed into water bodies by rainfall.
