|
| water corrosivity (Complex series of reactions between the water and metal surfaces and materials in which the water is stored or transported. The corrosion process is an oxidation/reduction reaction that returns refined or processed metal to their more stable ore state. With respect to the corrosion potential of drinking water, the primary concerns include the potential presence of toxic metals , such as lead and copper) |

| water endangering (Can be caused by a variety of means, e.g. farm pollution from animal wastes and silage liquor (liquors from green leaf cattle food which has had molasses added to promote fermentation and preservation; they are highly polluting and can be a seasonal cause of fish deaths in small streams), leachate from landfill sites, and spoil heaps, solvent discharge to sewers or to land and inadequate sewage treatment works) |

|
| water erosion (The breakdown of solid rock into smaller particles and its removal by water. As weathering, erosion is a natural geological process, but more rapid soil erosion results from poor land-use practices, leading to the loss of fertile topsoil and to the silting of dams, lakes, rivers and harbours. There are three classes of erosion by water. 1. Splash erosion occurs when raindrops strike bare soil, causing it to splash, as mud, to flow into spaces in the soil and to turn the upper layer of soil into a structureless, compacted mass that dries with a hard, largely impermeable crust. 2. Surface flow occurs when soil is removed with surface run-off during heavy rain. 3. Channelized flow occurs when a flowing mixture of water and soil cuts a channel, which is then deepened by further scouring. A minor erosion channel is called a rill, a larger channel a gully) |

| water for agricultural use (Water used in agriculture for irrigation and livestock. Livestock watering is only 1 percent of the total water withdrawal for agricultural use. Of all functional water uses, irrigation is the largest agricultural use of water) |

| water for consumption (Consumptive water use starts with withdrawal, but in this case without any return, e.g. irrigation, steam escaping into the atmosphere, water contained in final products, i.e. it is no longer available directly for subsequent use) |
