Question | Answer |

Groundwater | Water held below the water table in an aquifer |
Aquifer | a permeable rock which is capable of holding and transmitting groundwater |
Aquitard | An impermeable layer of rock incapable of transmitting economic quantities of water |
Live Aquifer | An aquifer which is replenished regularly by water inputs from the recharge surface area |
Fossil Aquifer | Aquifers which do not receive regular recharge due to to little precipitation in the area |
Abstraction | The removal of water from rivers, lakes and groundwater for human use |
Infiltration | The movement of water from rain or snow-melt into the soil |
Water Table | The upper surface of the zone of saturation in a permeable rock |
Artesian Basin | A Basin Structure containing water under hydrostatic pressure in a aquifer |
Cone of Depression | An area below or around a well, where the water table has been permanently lowered due to over abstraction of that well |
Natural Recharge | The Filling of Groundwater aquifers by rain or snow-melt percolating into the ground and saturating porous rocks |
Artificial Recharge | Adding Water to an aquifer through human effort |
Unconfined Aquifer | An aquifer not situated below and aquitard with the same hydrostatic pressure as the atmosphere |
Confined Aquifer | An aquifer situated below an aquitard, experiencing high hydrostatic pressure |
Hydrostatic Pressure | The Fluid Pressure exerted by the underlying column of water in a body of water when at rest |
Pontentiometric surface | The level to which water will rise in an aquifer |
