What is a characteristic of non-point source pollution?

Non-point source pollution is characterized by its origin from multiple, dispersed sources rather than a single identifiable point. This type of pollution typically arises from widespread activities such as agricultural runoff, urban stormwater runoff, and atmospheric deposition, making it challenging to pinpoint specific sources. Unlike point source pollution, which can be traced back to a single discharge location, non-point source pollution results from the cumulative effect of many different actions across a broader area. Consequently, the management and control of this type of pollution are more complex due to the diversity and wide distribution of its sources, often requiring collaborative efforts and comprehensive strategies rather than straightforward regulations.
