Point Source Pollution:Point source pollution refers to contamination that can be traced back to a specific and identifiable source, such as an industrial facility or sewage treatment plant.
Urban Runoff: Urban runoff is a type of non-point source pollution caused by rainwater flowing over paved surfaces in cities and picking up pollutants like oil, trash, and chemicals before entering water bodies.
Atmospheric Deposition: Atmospheric deposition occurs when pollutants in the air (such as acid rain) settle onto land or bodies of water, contributing to non-point source pollution.
