The casing protects aquifers which may contain freshwater. Aquifers are water-bearing geologic formations that can provide usable amounts of water. As used by hydrogeologists, an aquifer might be defined as ‘a stratum of soil or rock that can yield groundwater in economic or productive quantities’. Almost all wells used for water supply purposes are drilled into, and pump from, aquifers. Examples of aquifers in the United Kingdom include the Chalk or Sherwood Sandstone.Sometimes the porous rock layers become tilted in the earth. There might be a confining layer of less porous rock both above and below the porous layer. This is an example of a confined aquifer. In this case, the rocks surrounding the aquifer confines the pressure in the porous rock and its water.13 pri 2023 ...
