It is water leaving farm fields, in the form of rain or any other liquid effect and collecting animal waste, excess fertilizers and draining into and polluting streams and rivers. It endangers the water supplies for humans and the eco-systems
The runoff from the farm polluted the stream.
nonpoint source pollution
pesticide runoff from farm fields
lakes/rivers/lakes/dams/drinking reservoirs/ Regarding actual types of runoff, pesticides would most likely be found in farm and agricultural runoff resulting from ploughed furrows between crops.
Less farm and industrial runoff reaches such sea: farm runoff - with high quantities of fertilizer - provides the development of oxygen-consuming algae, which depletes the oxygen and kills marine life.
Runoff is water that flows over the ground surface. Snowmelt runoff is runoff from melting snow.
Runoff from rain and runoff from melting snow (which is NOT the same as glacial runoff).
Surface runoff and Subsurface runoff. Basically, above ground and below ground
New construction allowed runoff from hillsides which flooded basements in nearby homes.Runoff naturally seeks a path of least resistance.Continual runoff can undermine hills, leading to mudslides and ground failures.
runoff caused by construction working
acid rain comes from chemicals in the clouds, not runoff there is no "car runoff" runoff is from the slanted ground into water bodies
