What is groundwater mining?

Groundwater is any water that is pooled or moving beneath the surface of the earth. In some areas groundwater can be found in continuous flowing formations, rather like an underground river that is continually replenished by rainfall or snow melt. In other areas the groundwater, or aquifer, is more static, like a lake. These static areas are also replenished by water from the surface working its way down into the earth, but the process may be quite slow. As a consequence, some of the water in aquifers may have been there for a long time. For example, some of the water in the Madison Aquifer in the western US has been there for 20,000 years.
Groundwater mining is the process of locating aquifers and pumping the water out of them faster than the aquifer can replenish itself. Groundwater in these slow-refilling aquifers is essentially a nonrenewable resource.

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.
