In general, pollutants can be classified into point sources and nonpoint sources. The point source is a limited source of pollutants with limited discharge points, such as living sewage, industrial waste, and livestock wastewater. Non-point sources are mainly pollutants that are discharged along with surface runoff. It refers to plants, traffic pollutants, dust and garbage in urban areas, and air pollutants that fall on the ground. Therefore, the initial rainwater discharged with virtually all pollutants becomes the main nonpoint source.

In particular, in urban rivers, major pollutants such as various organic toxicities and heavy metals are calculated as nonpoint sources. Some countries, including the United States, actively regulate and treat nonpoint sources. It is increasingly recognized that nonpoint source control is important for water quality management.
