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
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.
Agricultural runoff from a large heavily tilled farm can significantly impact several natural systems, particularly water bodies such as rivers, lakes, and wetlands. The runoff often carries fertilizers, pesticides, and sediments, leading to nutrient pollution that can cause harmful algal blooms, oxygen depletion, and biodiversity loss in aquatic ecosystems. Additionally, soil erosion from tillage can degrade land quality and contribute to sedimentation in waterways, affecting habitats and water quality downstream. Terrestrial ecosystems can also be disrupted as runoff alters soil chemistry and affects plant and animal communities.
In spring of 2000 Walkerton's water supply became contanminated with highly dangerous 0157:H7 strain of E.Coli bateria from farm runoff
Runoff from rain and runoff from melting snow (which is NOT the same as glacial runoff).
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.
Decreasing the amount of agricultural runoff entering the water body will not increase the rate of eutrophication. Agricultural runoff contains nutrients like nitrogen and phosphorus that can contribute to eutrophication by promoting excessive algae and plant growth in the water.
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
