Water does not remain immobile in an aquifer but can seep out at springs or leak into other aquifers.The rate of movement may be very slow: in the Indus plain, the movement of saline (salty) groundwaters has still not reached equilibrium after 70 years of being tapped.The mineral content...
The water present beneath the surface occupying void soil spaces or within the fractures of rock formations is known as groundwater. A common name related to groundwater is an aquifer. An aquifer is a part of the rock or a viscous deposit which provides a usable quantity of water. ...
Groundwater is stored in a variety of rock types. A groundwater reservoir from which water can be extracted is called an aquifer. We can effectively think of an aquifer as a deposit of water. Extraction of water depends on two properties of the aquifer: porosity and permeability. Between sed...
Thus, for studies aiming to assess impacts on groundwater, only sampling sites of the third group should be used for reference sites as these are the most likely sites to have little surface impact and a stygofauna representative of the deeper aquifer. 展开 ...
