What is an example of point source pollution?

An example of point source pollution is the discharge of untreated wastewater from a factory directly into a river. This can result in high levels of pollutants such as heavy metals, chemicals, and pathogens being released into the water, causing harm to aquatic life and contaminating drinking water sources. Point source pollution is easier to regulate and control compared to non-point source pollution, as the source is identifiable and can be targeted for enforcement actions to prevent further pollution. In this case, the factory would need to implement proper treatment measures to reduce or eliminate the discharge of harmful pollutants into the water.
