Groundwater pollution (also called groundwater contamination) occurs when pollutants are released to the ground and make their way into groundwater.This type of water pollution can also occur naturally due to the presence of a minor and unwanted constituent, contaminant, or impurity in the groundwater, in which case it is more likely referred to as contamination rather than pollution.
This is an accepted version of this page This is the latest accepted revision, reviewed on 19 February 2025. Water located beneath the ground surface An illustration showing groundwater in aquifers (in blue) (1, 5 and 6) below the water table (4), and three different wells (7, 8 and 9) dug to reach it. Groundwater is the water present beneath Earth's surface in rock and soil pore spaces and in ...
Arsenic contamination of groundwater is a form of groundwater pollution which is often due to naturally occurring high concentrations of arsenic in deeper levels of groundwater. It is a high-profile problem due to the use of deep tube wells for water supply in the Ganges Delta , causing serious arsenic poisoning to large numbers of people.
The groundwater supply across the country is depleting at an alarming rate. A new study found that groundwater supplies around the world are depleting faster than they were 40 years ago.
When more groundwater is pumped from wells than replenished, storage of water in the aquifer is being mined, and the use of that water is no longer sustainable. As levels fail, it becomes more difficult to extract water, and pumps will struggle to maintain the design flow rate, which may consume more energy per unit of water.
Climate-driven extreme weather conditions, such as droughts and intense precipitation, may be accelerating the pace at which toxic nitrates are polluting groundwater, a recent study has found.
Surface and ground water stagnation; Trapped water stagnation. The water may be trapped in human artifacts (discarded cans, plant pots, tires, dug-outs, roofs, etc.), as well as in natural containers, such as hollow tree trunks, leaf sheaths, etc. To avoid ground and surface water stagnation, the drainage of surface and subsoil is advised.
