📚 Point Source Pollution: Defined
Point source pollution refers to pollutants that originate from a single, identifiable source. Think of a factory pipe discharging waste directly into a river. Because the origin is known and localized, it's usually easier to monitor and regulate.
🌍 Nonpoint Source Pollution: Defined
Nonpoint source pollution, on the other hand, comes from diffuse sources. It's pollution that doesn't have a single point of origin, making it much harder to trace and control. Common examples include runoff from agricultural fields, urban areas, or mining operations.
