  3. Aquifer - Wikipedia

    en.wikipedia.org/wiki/Aquifer

    An aquifer is an underground layer of water -bearing material, consisting of permeable or fractured rock, or of unconsolidated materials (gravel, sand, or silt). Aquifers vary greatly in their characteristics. The study of water flow in aquifers and the characterization of aquifers is called hydrogeology.

    When a water-bearing rock readily transmits water to wells and springs, it is called an aquifer. Wells can be drilled into the aquifers and water can be pumped out. Precipitation eventually adds water (recharge) into the porous rock of the aquifer.

    Aquifer, in hydrology, rock layer that contains water and releases it in appreciable amounts. The rock contains water-filled pore spaces, and, when the spaces are connected, the water is able to flow through the matrix of the rock. Wells drilled into aquifers are important sources of fresh water.

    A principal aquifer is defined as a regionally extensive aquifer or aquifer system that has the potential to be used as a source of potable (drinkable) water. For study or mapping purposes, aquifers are often combined into aquifer systems.

    An aquifer is a body of porous rock or sediment saturated with groundwater. Groundwater enters an aquifer as precipitation seeps through the soil. It can move through the aquifer and resurface through springs and wells.

  8. Water Tables and Aquifers - Education

    education.nationalgeographic.org/resource/water-tables-and-aquifers

    Pockets of water existing below the water table are called aquifers. An area's water table can fluctuate as water seeps downward from the surface. It filters through soil, sediment, and rocks. This water includes precipitation, such as rain and snow.

    Aquifers are underground layers of rock that are saturated with water that can be brought to the surface through natural springs or by pumping.

  10. 14.1: Groundwater and Aquifers - Geosciences LibreTexts

    geo.libretexts.org/Bookshelves/Geology/Physical_Geology_(Earle)/14:_Groundwater...

    An aquifer is defined as a body of rock or unconsolidated sediment that has sufficient permeability to allow water to flow through it. Unconsolidated materials like gravel, sand, and even silt make relatively good aquifers, as do rocks like sandstone.

  11. What is an aquifer? | U.S. Geological Survey - USGS.gov

    www.usgs.gov/media/audio/what-aquifer

    An aquifer is a geologic formation that can store and transmit water to wells, springs and some streams. An aquifer is more like a sponge than an underground river: geologic materials have connected pores that allow water to move from one space to another, but unless the rock is fractured, water does not move through large, hollow tunnels at ...
