PPT-Groundwater

Porosity and Permeability In order for rocks to transmit water oil or gas they must possess two properties 1 porosity and 2 permeability Porosity can be of two types The first is intergranular porosity which consists of pores between grains such as the quartz grains in a sandstone . Use of brackish groundwater could supplement or in some places replace the use of freshwater sources and enhance our Nations water security However a better understanding of the location and charac ter of brackish groundwater is needed to expand dev Hydraulic Head.

Although in the subsurface, it has a large impact on society and the features that we see on the surface of the Earth.. Makes up 23% of Earth’s freshwater.. 12% Shallow (we can reach). 11% Deep (out of our reach). Underground Layers. When precipitation occurs, water often seeps down into the soil and trickles down in between particles of soil and through cracks and spaces in layers of rock. . Percolating. Underground Stream.
