When groundwater is extracted from an aquifer, a cone of depression is created around the well.As the drafting of water continues, the cone increases in radius. Extracting too much water (overdrafting) can lead to negative impacts such as a drop of the water table, land subsidence, and loss of surface water reaching the streams.
Groundwater-related subsidence is the subsidence (or the sinking) of land resulting from unsustainable groundwater extraction.It is a growing problem in the developing world as cities increase in population and water use, without adequate pumping regulation and enforcement.
The over extraction of groundwater is a human caused activity that causes these ground failures that create pore spaces where water once was occupying. The sudden sinking of the soils surface causes infrastructure damage and a higher risk of flood damage due to the displacement of the Earth's surface.

Short-term economic gains made by conversion of forest to agriculture, or overexploitation of wood products, typically leads to loss of long-term income and long term biological productivity. West Africa , Madagascar , Southeast Asia and many other regions have experienced lower revenue because of overexploitation and the consequent declining ...
“Unfortunately, no use of groundwater has been determined by the courts to be ‘unreasonable.’ It’s basically a rule that benefits the biggest landowners with the deepest wells.’” Mayes told reporters Wednesday that the Arizona Legislature has done nothing to fix the groundwater problem despite knowing about the problem for years.
Groundwater is also used by farmers to irrigate crops and by industries to produce everyday goods. Most groundwater is clean, but groundwater can become polluted, or contaminated as a result of human activities or as a result of natural conditions. The many and diverse activities of humans produce innumerable waste materials and by-products ...
An irrigation scheme draws water from groundwater, rivers, lakes, or overland flow, and distributes it over a certain area. Hydrological , or direct, effects of doing this [ 1 ] include reduction in downstream river flow, increased evaporation in the irrigated area, increased level in the water table as groundwater recharge in the area is ...
