Which of the following aquifers require a low permeability zone above it or below it?

A) artesian aquifer
B) perched aquifer
C) confined aquifer
D) all of these

Artesian Aquifer

A confined aquifer containing groundwater under positive pressure, causing water to rise above the surrounding water table when tapped.

Confined Aquifer

A confined aquifer is a water-bearing stratum of permeable rock, sand, or gravel that is trapped between layers of impermeable rock and is under pressure.

Perched Aquifer

A perched aquifer is a groundwater body that sits above the main water table, separated by a layer of impermeable rock or sediment, typically providing a limited and localized water source.

  • Understand the principle of confined and unconfined aquifers, along with the structures associated with them such as artesian wells.

Final Answer :
D
Explanation :
All of these aquifers require a low permeability zone either above or below them to maintain their specific conditions. An artesian aquifer is a type of confined aquifer that is under pressure, requiring a low permeability layer above it to maintain pressure. A perched aquifer requires a low permeability layer below it to hold water above the main water table. A confined aquifer is sandwiched between two low permeability layers to keep it pressurized.
