Which source of water pollution includes oil and gasoline discharge from automobiles and storm sewers drainage?

The source of water pollution that includes oil and gasoline discharge from automobiles and storm sewer drainage is known as non-point source pollution. This type of pollution occurs when contaminants are carried over land and enter water bodies through runoff, often during rainfall events. Unlike point source pollution, which comes from a single, identifiable source, non-point source pollution is diffuse and can be challenging to manage and regulate.
