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.
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.

Groundwater extraction is the primary cause of saltwater intrusion. Groundwater is the main source of drinking water in many coastal areas of the United States, and extraction has increased over time. Under baseline conditions, the inland extent of saltwater is limited by higher pressure exerted by the freshwater column, owing to its higher ...
California's water board has for the first time put a farming region on probation for failing to adopt measures to curb excessive pumping of groundwater.
“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.
