Non-point source pollution refers to contaminants that enter water bodies from multiple, diffuse sources rather than a single identifiable point. This type of pollution is often a result of runoff from rain or snowmelt, where various pollutants like sediments, nutrients, and chemicals accumulate over large areas and are washed into waterways. The widespread nature of non-point source pollution makes it challenging to control and regulate, as it does not originate from one specific location.
