There are ways in which ground water can be extracted from the earth’s surface for a score of uses. It can be used for home purposes, industrial usage, in addition to agricultural use for activities like irrigation. This can be possible by construction of extraction wells that draws water underneath the surface of the earth. Ground water has been distributed differently under the surface of the earth. In addition, underground water undergoes movement under the earth’s ground. Study of ground water motions, plus distribution is known as hydrogeology. It is also called ground water hydrology. Ground water can also include soil moisture, immobile water that is found in bedrocks that have very low permeability, and oil formation water that is found very deep in the earth’s surface. Ground water is thought to act as lubricants that cause movement of faults. The points under the surface of the earth where ground water originates are identified as aquifers. An aquifer has layers of porous materials that contain and transmit water. When aquifer is not confined, water can move freely between the earth’s surface and the saturated zone of an aquifer. Since gravity causes water to move downwards, deeper zones of the aquifer are further saturated as compared to the upper parts. Water table refers to the upper zone of the saturated layer of an unconfined aquifer. Below the water table, all spore spaces are saturated with water. This zone is known as phreatic zone. There is a substrate that slight porosity and allows little transmission of ground water. This substrate is called an aquitard. Aquifers have diverse features depending on the geology, and the structure of the substrate as well as the topography in which they happen. Aquifers that contain a high amount of water are situated in sedimentary geologic formations. Crystalline rocks that are weathered and fractured produce a
