What is the lower region of groundwater where all the pores in a rock or sediment are filled with water?
Hi Jennifer, It is an aquifer that you are mostly likely referring to. I hope this helps : ) Jess An aquifer is a large body of permeable material where groundwater is present and fills all pore space. Good aquifers are those with high permeability such as poorly cemented sands, gravels, or highly fractured rock. An aquitard is a body of material with very low permeability. In general, tightly packed clays, well cemented sandstones, and igneous and metamorphic rocks lacking fractures are good aquitards.
