Which of the following best describes the nature of runoff pollution?

Runoff pollution is best described as being widely dispersed across a large area because it is often the result of precipitation flowing over various surfaces, picking up pollutants from diverse sources such as roads, fields, and urban areas. As water flows, it collects sediments, nutrients, heavy metals, and contaminants, which can originate from multiple points rather than from a single location. This dispersal makes runoff pollution particularly challenging to address, as it can carry a mixture of pollutants from different sources, resulting in contamination of water bodies that may be far from the origin of the runoff. Tracking and monitoring this type of pollution is complex due to its widespread nature, which is why it is considered an environmental concern across extensive regions rather than stemming from identifiable, single points.
