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.
[7] [8] Groundwater recharge occurs through mineral soils found primarily around the edges of wetlands. [9] The soil under most wetlands is relatively impermeable. A high perimeter to volume ratio, such as in small wetlands, means that the surface area through which water can infiltrate into the groundwater is high. [8]

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 ...
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.
Environmental impact of fracking in the United States has been an issue of public concern, and includes the contamination of ground and surface water, methane emissions, [1] air pollution, migration of gases and fracking chemicals and radionuclides to the surface, the potential mishandling of solid waste, drill cuttings, increased seismicity and associated effects on human and ecosystem health.
Groundwater is water present below the ground surface that saturates the pore space in the subsurface. Globally, between 25 per cent and 40 per cent of the world's drinking water is drawn from boreholes and dug wells. [1] Groundwater is also used by farmers to irrigate crops and by industries to produce
"The effect will be long-lasting," said Ty Higgins, director of communications for the Ohio Farm Bureau. Of the Buckeye State's 88 counties, 87 were highlighted as parched when the U.S. Drought ...
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 ...
