Such programs are much needed because in many arid lands there is only a vague idea of the extent of groundwater resources. It is known, however, that the distribution of groundwater is uneven, and that much of it lies at great depths.Groundwater is stored in the pore spaces and joints...
Nearly 50 percent of all groundwater is stored in the upper 1,000 meters of Earth. At greater depths within Earth, the pressure of the overlying rock causes pores and cracks to close, reducing the space that pore water can occupy, and almost complete closure occurs at a depth of about ...

【Paragraph 2】Groundwater is stored in a variety of rock types. A groundwater reservoir from which water can be___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...
Water is mainly stored in the pore spaces of the formation and thus the yield is quite good from the aquifers of this region. But the suitability of this water for human use not only depends on quantity of groundwater available but also to a great extent on the chemical quality of ground...
