Point source pollution refers to contaminants that enter a water body from a single, identifiable source. This type of pollution is often associated with specific locations, such as factories, wastewater treatment plants, or sewage outfalls. Because the source is easily identifiable, it is generally easier to regulate and manage compared to non-point source pollution. Common examples of point source pollution include the discharge of industrial waste into rivers or the release of chemicals from a single pipe. Monitoring and controlling these discharges is crucial for protecting water quality and aquatic ecosystems, as they can lead to significant environmental and health issues if left unchecked.
