GENERAL GEOLOGY

Detailed explanation-1: -An aquifer is a geological formation in which groundwater flows through with ease. Aquifers should therefore have both permeability and porosity. Examples of these geological formations which form aquifers include sandstone, conglomerate, fractured limestone, and unconsolidated sand and gravel formations.

Detailed explanation-2: -An aquifer is a body of saturated rock through which water can easily move. Aquifers must be both permeable and porous and include such rock types as sandstone, conglomerate, fractured limestone and unconsolidated sand and gravel.

Detailed explanation-3: -Permeability is a measure of the interconnectedness of pores. The connection between pore spaces allows groundwater to flow through the sediment or rock. The combination of water storage (porosity) and flow (permeability) makes a good aquifer-a rock unit or sediment that contains usable groundwater.

Detailed explanation-4: -How are aquifers formed? Aquifers fill when stormwater that originates from rain and snow melt infiltrates into the ground until it reaches impermeable rock layers that do not let the water flow through, so it is stored underground. Stormwater that infiltrates into the soil recharges the porous rocks of aquifers.

Detailed explanation-5: -An aquifer is a body of porous rock or sediment saturated with groundwater. Groundwater enters an aquifer as precipitation seeps through the soil. It can move through the aquifer and resurface through springs and wells.
