Water is the chemical substance with the formula H2O. It is a colorless, odorless, and tasteless liquid. Water exists on Earth in solid, liquid, and gas forms. Water resources are sources of water that are useful or potentially useful to humans and include surface water, groundwater, and fresh water. Surface water includes water in rivers, lakes, and wetlands, which is replenished by precipitation and lost through discharge and evaporation. Groundwater is water located below the earth's surface but within 2,500 feet of the surface. The importance of water includes uses in agriculture, drinking, washing, fire extinction, recreation, and industrial applications.
