Water is an inorganic, transparent, tasteless, odourless, and almost colourless chemical substance.
Water resources are natural water resources that may be valuable to humans, such as a source of drinking water or irrigation water.
Only 3% of the water on Earth is fresh water, with little more than two-thirds frozen in glaciers and polar ice caps.
Rivers, streams, lakes, reservoirs, springs, and groundwater are examples of bodies of water that give water to public drinking water sources and private wells.
Sources of water can include: Water on the surface (for example, a lake, river, or reservoir), Water from the ground (for example, an aquifer)
