A process whereby groundwater is removed from an aquifer at a rate greater than it can be recharged, resulting in ever-lowering groundwater levels. See overdraft.
When discharge from an aquifer, usually due to groundwater pumping for municipal and business use, exceeds recharge.
The removal of groundwater from an aquifer in excess of the rate of natural or artificial recharge. Continued groundwater mining reduces the groundwater supply until it is no longer an economical source of water.
The withdrawal of water from an aquifer in excess of recharge over a period of time. If continued, the underground supply would eventually be exhausted or the water table could drop below economically feasible pumping lifts.
The process, deliberate or inadvertent, of extracting groundwater from a source at a rate in excess of the replenishment rate such that the groundwater level declines persistently, threatening exhaustion of the supply or at least a decline of pumping levels to uneconomic depths.pits, ditches, furrows, streambed modifications, or injection wells.
Pumping groundwater from a basin where the safe yield is very small, thereby extracting groundwater which had accumulated over a long period of time.
(Also known as groundwater overdraft, groundwater overexploitation.) Extracting groundwater at a rate that exceeds its recharge, so that there is a net loss of groundwater.
