Nonpoint Source Pollution
Nonpoint source pollution refers to contamination of water that comes from multiple, diffuse sources rather than a single, identifiable source. For example, when rainwater runs off streets, farms, or parking lots, it can carry pollutants like fertilizers, pesticides, oil, and litter into rivers, lakes, and oceans. Unlike pollution from a factory or sewage treatment plant, which is easy to pinpoint, nonpoint source pollution is scattered and harder to manage, making it a significant challenge for environmental protection efforts. Addressing it often involves community action and better land use practices.

Nonpoint source pollution refers to contaminated runoff that comes from multiple, diffuse sources rather than a single point, like a factory or sewage treatment plant. It occurs when rainwater or snowmelt washes pollutants—such as fertilizers, pesticides, oil, and litter—off surfaces like roads, fields, and urban areas into waterways. Because it's hard to pinpoint the exact origin of this pollution, it poses challenges for management and regulation. This type of pollution can affect water quality, harm aquatic life, and impact human health, making it an important concern for environmental protection efforts.
