What is aquifer system.

Schematic of an aquifer showing confined zones, groundwater travel times, a spring and a well. An aquifer is an underground layer of water-bearing, permeable rock, rock fractures, or unconsolidated materials (gravel, sand, or silt). Groundwater from aquifers can be extracted using a water well. The Glacial aquifer system ranks first in the nation as a source of groundwater for public and domestic supply, providing 2.6 billion gallons per day for this use.

Scientists tested for hundreds of water-quality constituents and ...In this video we are going to discuss What is Aquifer? What are the difference between Unconfined Aquifer And Confined Aquifer? Class XII Geography Urdu H...A confined aquifer can be simulated with a length of garden hose that is filled with water and sediment, then capped on one end. The saturated sediment represents the confined aquifer and the hose walls represent the “confining beds”. When the open end of the hose (aquifer recharge area) is raised, the potential energy of the system increases.
