What characterizes non-point source pollution?

Non-point source pollution is characterized by its origin from multiple, diffuse sources rather than a single, identifiable one. This type of pollution typically results when precipitation runs off over land surfaces, carrying with it various pollutants such as fertilizers, pesticides, and sediment from agricultural fields, urban areas, and natural landscapes. Because non-point source pollution comes from various locations, it can be much more challenging to regulate and address compared to point source pollution, which can be traced back to specific pipes, outlets, or facilities.

The other options describe different aspects of pollution. Identifying pollution from a single source pertains to point source pollution. It's important to note that non-point source pollution isn't exclusively tied to industrial processes; it also stems from everyday activities and natural landscape interactions. Lastly, non-point source pollution can affect broad areas, making it difficult to manage effectively, unlike localized pollution, which is easier to address since its source is confined and easily identified.
