Runoff is the draining away of water from the surface of an area of land when the rain hits the surface.


It can carry pollutants through its path and when it reaches to the water reservoirs it can pollute the water. Especially if runoff carry phosphorus containing materials to a lake, then algea growth can happen and eutrophication problem will occur.
