Nonpoint source pollution (NPS), also known as polluted runoff, is caused by rainfall or snowmelt moving over or through the ground. As the runoff moves, it picks up and carries away natural and human-made pollutants, finally depositing them into lakes, rivers, wetlands, and coastal waters.
Because it is a diffuse source, underground pollution from poorly performing septic systems is also included.
