Ground water is water below the land surface that fills the spaces between grains of sediment and rocks, or fills cracks and fractures in the rock. Saturated zones in sediment such as sand and gravel, and in fractured rock formations, that receive, store, and transmit water to wells are calledaquifers. Clean and plentiful ground water is a vital resource for personaland economic health everywhere in the United States. Each day, over130 million Americans get their drinking water from ground water. About 40 million are supplied from individual home wells.
