If raw or improperly treated sewage is discharged to a stream on purpose or by misadventure (pipe breaks, leaks etc.) it can pollute the water by: * Increasing the burden of fecal organisms * Adding chemical contaminants * Depleting the oxygen levels in the water * Making the water aesthetically unappealing (foams, solids and odours) * Covering the stream bed with solids

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.
From run off because, When the run off is collection acids and pollution it carries it with it and then runs down into the sewers witch reach sewage treatment plants. Some street drainers lead to oceans
