Non-point Source Pollution
Non-point Source Pollution refers to water pollution that comes from many scattered sources rather than a single identifiable point. Think of it like rain collecting dirt from many places as it flows across land, rather than pollution coming from a single factory pipe. Water resource professionals work on identifying these pollution sources and creating plans to reduce them. This is different from "point source pollution" which comes from a specific location like a factory or sewage plant. This type of work is crucial for protecting drinking water, keeping rivers and lakes clean, and managing stormwater in cities and agricultural areas.
