An aquifer is an underground layer of water-bearing permeable rock or unconsolidated materials (gravel, sand, or silt) from which groundwater can be extracted using a water well. The study of water flow in aquifers and the characterization of aquifers is called hydrogeology. Related terms include aquitard, which is a bed of low permeability along an aquifer,[1] and aquiclude (or aquifuge), which is a solid, impermeable area underlying or overlying an aquifer. If the impermeable area overlies the aquifer pressure could cause it to become a confined aquifer.
Water and energy are two of the things we pretty much take for granted – but we shouldn’t. Water is not infinite, and if you consume it at a high enough rate, it will run out; meanwhile, there’s a tight connection between living standard and energy consumption – and as the population continues to increase [...]
Groundwater use is unsustainable in many of the world’s major agricultural zones; as a matter of fact, about a quarter of the world’s population lives in regions where groundwater is being used up faster than it can be replenished, concluded researchers. The planet thirsts Our entire civilization depends on our water supply, and aside from [...]
