Non-point source pollution refers to the contamination of water bodies that arises from multiple diffuse sources rather than a single, identifiable point. It often occurs when rainfall or snowmelt moves over and through the ground, picking up pollutants like fertilizers, pesticides, and sediments as it flows into rivers, lakes, and oceans. This type of pollution is particularly challenging to manage because it lacks a specific origin, making it harder to regulate and mitigate compared to point source pollution.
