Dünyanın tatlı suyunun %68'inden fazlası buzda ya da buzullarda kilitlidir; ve diğer %30'u yeraltı suyudur. - Over 68 percent of Earth's freshwater is locked up in ice and glaciers; and another 30 percent is in groundwater.
Water found beneath the earth’s surface that fills pores between sand, soil particles, or gravel creating a saturated zone In aquifers, ground water is in sufficient quantities that it can be used for drinking water, irrigation, or other purposes
Underground water that is generally found in the pore space of rocks or sediments and that can be collected with wells, tunnels, or drainage galleries, or that flows naturally to the earth's surface via seeps or springs < back to top H
Water found below the surface of the land, usually in porous rock formations Ground water is the source of water found in wells and springs and is used frequently for drinking
Water in the ground that is in the zone of saturation, from which wells, springs, and ground-water runoff are supplied (After Meinzer, 1949, p 385 )
Subsurface water occupying the zone of saturation In a strict sense the term applied only to water below the water table
The supply of fresh water found beneath the Earth's surface (usually in aquifers) which is often used for supplying wells and springs Because ground water is a major source of drinking water, there is growing concern over areas where leaching agricultural or industrial pollutants or substances from leaking underground storage tanks are contaminating ground water
Water occurring in an aquifer below the surface of the ground The term is not applied to water that is percolating or held in the top layers of the soil, but to that below the water table
All the waters found beneath the surface of the earth which are contained within or under this State or any portion thereof, except such waters as are confined and retained completely upon the property of one person and do not drain into or connect with any other waters of the State
The supply of fresh water found beneath the Earth's surface, usually in aquifers, which supply wells and springs Because ground water is a major source of drinking water, there is growing concern over contamination from leaching agricultural or industrial pollutants or leaking underground storage tanks
Water beneath the earth's surface Water at sea level; water which has long been in contact with the limestone; water which is supersaturated Ground water level is the water table, the depth or elevation above or below sea level at which the surface of ground water stands
The supply of fresh water under the earth's surface in an aquifer or in the soil
The portion of the subsurface water which is in the zone of saturation where nearly all openings particles are filled with water The between soil n in the ground is top of the zone of saturation called the water-table
water occurring in the zone of saturation in an aquifer or soil List of Glossary Terms
Water within the earth that supplies wells and springs; water in the zone of saturation where all openings in rocks and soil are filled, the upper surface of which forms the water table Also termed Phreatic water
The subsurface water supply in the saturated zone below the level of the water table
In general, any water that exists beneath the land surface, but more commonly applied to water in fully saturated soils and geologic formations
That portion of the water below the ground surface that is under greater pressure than atmospheric pressure
(1) water that flows or seeps downward and saturates soil or rock, supplying springs and wells The upper surface of the saturate zone is called the water table (2) Water stored underground in rock crevices and in the pores of geologic materials that make up the Earth's crust
Ground water, as opposed to surface water, is water that does not run off, and is not taken up by plants, but soaks down into an aquifer; a supply of fresh water under the earths surface which forms a natural reservoir
Water beneath the earth's surface that fills pores between materials such as sand, soil or gravel Groundwater is a major source of water for agricultural and industrial purposes and is an important source of drinking water for about half of all Americans
Groundwater is that subsurface water contained in the interconnected pore spaces below the water table of an aquifer Groundwater will occur where there is an impermeable subsurface barrier that allows water flowing through the unsaturated zone to be collected and stored within the interconnected pore spaces at depth This impermeable barrier may be bedrock or an impermeable layer of rock Once collected in the saturated zone, groundwater will flow from areas where the water table is highest toward areas where it is lowest This percolation of water through the saturated zone is powered by gravity Eventually, percolating water may leave the groundwater system and be discharged into streams or other surface water bodies
Water in the subsurface which is beneath the water table and thus present within the saturated zone In contrast to water present in the unsaturated, or vadose zone which is referred to as soil moisture
Underground water that fills pores in soil or openings in rocks to the point of saturation Where groundwater occurs in significant quantity, it can be used as a water supply
The supply of fresh water found beneath the surface of the Earth (usually in aquifers) that often supplies wells and springs (Source: Carbon Dioxide Information Analysis Center, 1990)
(1) Water occurring below the soil surface that is held in the soil itself (2) Subsurface water, or water stored in the pores, cracks, and crevices in the ground below the water table (3) Water occurring in the zone of saturation below the earth's surface
1 Water that flows or seeps downward and saturates soil or rock, supplying springs and wells The upper surface of the saturated zone is called the water table 2 Water stored underground in rock crevices and in the pores of geologic materials that make up the Earth's crust (see surface water)
- The subsurface water within the zone of saturation This water moves under the influence of gravity and is, in many instances, a source of well water for domestic and agricultural use
Groundwater is water that is found under the ground. Groundwater has usually passed down through the soil and become trapped by rocks. water that is below the ground. or subsurface water Water that occurs below the surface of the Earth, where it occupies spaces in soils or geologic strata. Most groundwater comes from precipitation, which gradually percolates into the Earth. Typically, 10-20% of precipitation eventually enters aquifers. Most groundwater is free of pathogenic organisms, and purification for domestic or industrial use is not necessary. Furthermore, groundwater supplies are not seriously affected by short droughts and are available in many areas that do not have dependable surface water supplies
water beneath the earth's surface that fills the spaces and flows between soil particles and rock Groundwater is what you find in wells and springs Two out of every three Wisconsin citizens drink groundwater
