The pollution may come from a variety of sources, ranging from point source water pollution (from a single discharge point) to more diffuse, landscape-level causes, also known as non-point source pollution and air pollution. Once in the environment these pollutants can have both direct effects in surrounding ecosystems, i.e. killing local ...
There are two primary sources of pollution for nitrogen: agriculture and septic systems. Agriculture can contribute from heavy use of fertilizer as well as animal agriculture waste. Over 68 published and peer-reviewed studies have been conducted since 2002, out of these studies 15 found direct links to groundwater pollution from animals' waste ...

Animal agriculture is a cause of harmful particulate matter pollution in the atmosphere. This type of production chain produces byproducts; endotoxin, hydrogen sulfide , ammonia, and particulate matter (PM), such as dust, [ 60 ] [ 61 ] all of which can negatively impact human respiratory health. [ 62 ]
These chemicals may also enter runoff from crop residues, irrigation water, wildlife, and atmospheric deposition. [3]: p. 2–9 Farmers can develop and implement nutrient management plans to mitigate impacts on water quality by: mapping and documenting fields, crop types, soil types, water bodies; developing realistic crop yield projections
A practical definition of water pollution is: "Water pollution is the addition of substances or energy forms that directly or indirectly alter the nature of the water body in such a manner that negatively affects its legitimate uses." [1]: 6 Water is typically referred to as polluted when it is impaired by anthropogenic contaminants.
Stable stratification of fluids occurs when each layer is less dense than the one below it. Unstable stratification is when each layer is denser than the one below it. Buoyancy forces tend to preserve stable stratification; the higher layers float on the lower ones. In unstable stratification, on the other hand, buoyancy forces cause convection ...
Most of the organisms involved are derived from the waste, wastewater or water stream itself or from the atmosphere or soil water. However some processes, especially those involved in removing very low concentrations of contaminants, may use engineered eco-systems created by the introduction of specific plants and sometimes animals.
