Point Source Pollution: Point source pollution refers to contaminants discharged from identifiable sources such as factories or sewage treatment plants.
Non-point Source Pollution: Non-point source pollution refers to pollutants that enter water bodies from diffuse sources like agricultural runoff or urban stormwater runoff.
