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.
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.
Topsoil runoff from farm, central Iowa (2011). Water pollution in the United States is a growing problem that became critical in the 19th century with the development of mechanized agriculture, mining, and manufacturing industries—although laws and regulations introduced in the late 20th century have improved water quality in many water bodies.

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.
Nov. 1—As the U.S. Army continues determining how best to clean up groundwater contamination caused by a former biowarfare test site in Frederick, researchers are also studying what protective ...
Since the Hinkley groundwater contamination lawsuit, a group of California-based scientists with organizations such as the Desert Sierra Cancer Surveillance Program (DSCSP) and ChemRisk have argued against the claim that chromium 6 is genotoxic, downplaying the number of cancer cases and challenging a "cancer cluster in the Hinkley area".
As an ingredient in unleaded gasoline, MTBE is the most water-soluble component. When dissolved in groundwater, MTBE will lead the contaminant plume with the remaining components such as benzene and toluene following. Thus the discovery of MTBE in public groundwater wells indicates that the contaminant source was a gasoline release.
Following initial discoveries of groundwater contamination in 2002, the Minnesota Department of Health conducted numerous studies –concluding in 2008, 2010, and 2014 – on the level of PFAs found in the bloodstreams of exposed residents. On February 20, 2018, the state of Minnesota settled its lawsuit against 3M in exchange for $850 million.
