Document Summary

0. 63% of water but is significant because it is the dominant reservoir of liquid fresh water. Much of it is not fresh, but saline (either connate or rendered saline by host sediment) There is water in pore spaces of rocks to great depths. Incompletely saturated, has water and atmospheric gases (also called unsaturated zone) Water in pores coats the surfaces of the grains and lines the pores. Where percolation ceases, pores are 100% saturated. The water is irregular not perfectly horizontal. Lakes, streams and oceans are places where the water table is above the earth"s surface. The difference in elevation between source and elevation of groundwater. (produces a stronger flow) Cracks in the material that is not filled by solid material. Rocks with high porosity and permeability (sandstones and conglomerate) Rocks with low permeability (shales, igneous, and metamorphic rocks) (wells here: water rises to height of water table, but needs to be pumped to ground surface)
