Articles from Britannica Encyclopedias for elementary and high school students. Valuable species of game fish (e.g., trout) cannot survive in water with very low levels of dissolved oxygen. It is an essential source for the existence of life on the planet earth. 0 && stateHdr.searchDesk ? When the algae die, oxygen dissolved in the water declines because microorganisms use oxygen to digest algae during the process of decomposition (see also biochemical oxygen demand). Sewage can promote algae growth, which can eventually result in eutrophic dead zones where aquatic life cannot survive because of a lack of oxygen.

The reservoir's capacity is 9,835 acre-feet of water. Water helps to restore fluids lost through metabolism, breathing, sweating, and the removal of waste. Another ocean pollution problem is the seasonal formation of dead zones (i.e., hypoxic areas, where dissolved oxygen levels drop so low that most higher forms of aquatic life vanish) in certain coastal areas. From Middle English water, from Old English wter (water), from Proto-West Germanic *watar, from Proto-Germanic *watr (water), from Proto-Indo-European *wdr (water). Solid waste includes garbage, rubbish, electronic waste, trash, and construction and demolition waste, all of which are generated by individual, residential, commercial, institutional, and industrial activities.

Some other reactive metals, such as aluminum and beryllium, are oxidized by water as well, but their oxides adhere to the metal and form a passive protective layer. [95][96] In 1805, Joseph Louis Gay-Lussac and Alexander von Humboldt showed that water is composed of two parts hydrogen and one part oxygen. Clouds consist of suspended droplets of water and ice, its solid state. [94] The operating potential is actually 1.48 V or higher in practical electrolysis. A dispersed (or nonpoint) source is a very broad unconfined area from which a variety of pollutants enter the water body, such as the runoff from an agricultural area. The properties of water have historically been used to define various temperature scales. Physical and chemical properties of pure water, "HOH" redirects here. When finely divided, crystalline ice may precipitate in the form of snow. Anaerobic organisms (organisms that do not require oxygen to live) then metabolize the organic wastes, releasing gases such as methane and hydrogen sulfide, which are harmful to the aerobic (oxygen-requiring) forms of life.

Sources of chemical contaminants include poorly designed or poorly maintained subsurface sewage-disposal systems (e.g., septic tanks), industrial wastes disposed of in improperly lined or unlined landfills or lagoons, leachates from unlined municipal refuse landfills, mining and petroleum production, and leaking underground storage tanks below gasoline service stations. Dead zones occur worldwide; one of the largest of these (sometimes as large as 22,730 square km [8,776 square miles]) forms annually in the Gulf of Mexico, beginning at the Mississippi River delta.
