Runoff of soil and fertilizer on a farm field during a rain storm. Nonpoint source (NPS) water pollution regulations are environmental regulations that restrict or limit water pollution from diffuse or nonpoint effluent sources such as polluted runoff from agricultural areas in a river catchments or wind-borne debris blowing out to sea.
The Tennessee attorney general has accused a Clay County farmer of flouting state law by allowing large amounts of cow waste to flow into waterways. Tennessee sues farmer with 6,000 cows, missing ...
[1] [2] Together with runoff and leaching, drift is a mechanism for agricultural pollution. [3] Some drift results from contamination of sprayer tanks. [4] Farmers struggle to minimize pesticide drift and remain productive. [5] Research continues on developing pesticides that are more selective, [6] but the current pesticides have been highly ...
Agricultural wastewater treatment is a farm management agenda for controlling pollution from confined animal operations and from surface runoff that may be contaminated by chemicals in fertilizer, pesticides, animal slurry, crop residues or irrigation water. Agricultural wastewater treatment is required for continuous confined animal operations ...
Usually, permitted point sources of water pollution, such as wastewater treatment plants, have high discharge treatment costs, whereas nonpoint sources of water pollution, such as agriculture, have low costs of pollution reduction. Therefore, it is generally assumed that most trades would take place between point sources and nonpoint sources. [54]
Manure in the water runoff from his farm was so severely polluting creeks and streams in the area, according to the Tennessee Department of Environment and Conservation, that the department warned ...
Topsoil runoff from farm, central Iowa (2011). Water pollution in the United States is a growing problem that became critical in the 19th century with the development of mechanized agriculture, mining, and manufacturing industries—although laws and regulations introduced in the late 20th century have improved water quality in many water bodies.

Much agricultural pollution is exacerbated by surface runoff, leading to a number of down stream impacts, including nutrient pollution that causes eutrophication. In addition to causing water erosion and pollution, surface runoff in urban areas is a primary cause of urban flooding , which can result in property damage, damp and mold in ...
