agricultural runoff
Cropland water pollution
Agricultural runoff is water that flows over farmland and carries soil, fertilizers, pesticides, and animal waste into streams, rivers, and groundwater.
It's a major source of water pollution, causing algae blooms and oxygen-depleted dead zones in lakes and coastal waters: Agricultural runoff from Midwest farms has created a massive dead zone in the Gulf of Mexico.
