What is nonpoint source pollution?


Nonpoint source pollution is also known as "runoff pollution." Nonpoint source pollution is a major contributor to water pollution in the United States and in other countries. Unlike point source pollution, which enters the water from specific locations (such as a discharge pipe from a factory or wastewater facility, an oil or chemical spill) nonpoint source pollution comes from a broader area. Nonpoint source pollutants are picked up and transported during rain and snowmelt events. The rain and/or snowmelts pick up human-made and/or natural pollutants and transport them into lakes, rivers, wetlands, and groundwater.
