Pollution from these landscapes has been almost universally acknowledged as the most pressing challenge to the restoration of waterbodies and aquatic ecosystems nationwide." [14]: 24 An open runoff system in Africa. The runoff also increases temperatures in streams, harming fish and other organisms. (A sudden burst of runoff from a rainstorm ...
Surface runoff is defined as precipitation (rain, snow, sleet, or hail [5]) that reaches a surface stream without ever passing below the soil surface. [6] It is distinct from direct runoff, which is runoff that reaches surface streams immediately after rainfall or melting snowfall and excludes runoff generated by the melting of snowpack or ...
This can release nitrogen oxide, carbon monoxide, sulphur dioxide, or hydrocarbons into the air. Liquid pollution can come from railways contributing to a runoff into water sources, like groundwater or rivers and can result from spillage of fuels like oil into water supplies or onto land or discharge of human waste.

Air pollution from fossil (and some biofuel) powered vehicles can occur wherever vehicles are used and are of particular concern in congested city street conditions and other low speed circumstances. Emissions, also referred to as exhaust gas , include particulate emissions from diesel engines , NO x , [ 11 ] volatile organic compounds , [ 12 ...
Nonpoint source air pollution affects air quality, from sources such as smokestacks or car tailpipes. Although these pollutants have originated from a point source, the long-range transport ability and multiple sources of the pollutant make it a nonpoint source of pollution; if the discharges were to occur to a body of water or into the ...
This has major environmental implications, including pollution runoff and the altering of important shorelines. "One-third of Puget Sound shoreline has already been altered". [11] Under the Growth Management Act (GMA), local governments plan, coordinate and manage for growth in Washington, while protecting natural resources and public interests.
These externalities include factors such as air pollution, noise, traffic congestion, and road maintenance costs, which affect the broader community and environment. Additionally, these externalities contribute to social injustice, as disadvantaged communities often bear a disproportionate share of these negative impacts. .
[39] This pollution is a result of numerous factors such as runoff, application and spray from vehicles. [39] In Canada, there has been research that shows that "salt run-off from roads can increase local chloride levels to between 100 and 4,000 times normal levels."
