Groundwater pollution most often results from improper disposal of wastes on land. Major sources include industrial and household chemicals and garbage landfills , industrial waste lagoons, tailings and process wastewater from mines, oil field brine pits, leaking underground oil storage tanks and pipelines, sewage sludge and septic systems.
Polluted groundwater is mapped by sampling soils and groundwater near suspected or known sources of pollution, to determine the extent of the pollution, and to aid in the design of groundwater remediation systems.
Preventing groundwater pollution near potential sources such as landfills requires lining the bottom of a landfill with watertight materials, collecting any leachate with drains, and keeping rainwater off any potential contaminants, along with regular monitoring of nearby groundwater to verify that contaminants have not leaked into the groundwater.
Pollution can occur from landfills, naturally occurring arsenic, on-site sanitation systems or other point sources, such as petrol stations with leaking underground storage tanks, or leaking sewers.
Movement of water and dispersion within the aquifer spreads the pollutant over a wider area, its advancing boundary often called a plume edge, which can then intersect with groundwater wells or daylight into surface water such as seeps and springs , making the water supplies unsafe for humans and wildlife.
Different mechanism have influence on the transport of pollutants, e. The interaction of groundwater contamination with surface waters is analyzed by use of hydrology transport models. The danger of pollution of municipal supplies is minimized by locating wells in areas of deep groundwater and impermeable soils, and careful testing and monitoring of the aquifer and nearby potential pollution sources. Of this, about 10 percent, approximately million people, obtains water from groundwater resources that are heavily polluted with arsenic or fluoride.
New method of identifying substances that are hazardous to health[ edit ] In , the Swiss Aquatic Research Institute, Eawag, presented a new method by which hazard maps could be produced for geogenic toxic substances in groundwater. This offers specialists worldwide the possibility of uploading their own measurement data, visually displaying them and producing risk maps for areas of their choice. GAP also serves as a knowledge-sharing forum for enabling further development of methods for removing toxic substances from water.
Regulations[ edit ] The examples and perspective in this section deal primarily with the United States and do not represent a worldwide view of the subject. You may improve this section , discuss the issue on the talk page , or create a new article , as appropriate. July United States[ edit ] In the United States, laws regarding ownership and use of groundwater are generally state laws; however, regulation of groundwater to minimize pollution of groundwater is by both states and the federal-level Environmental Protection Agency.
Ownership and use rights to groundwater typically follow one of three main systems:  The Rule of Capture provides each landowner the ability to capture as much groundwater as they can put to a beneficial use, but they are not guaranteed any set amount of water. As a result, well-owners are not liable to other landowners for taking water from beneath their land. State laws or regulations will often define "beneficial use", and sometimes place other limits, such as disallowing groundwater extraction which causes subsidence on neighboring property.
Limited private ownership rights similar to riparian rights in a surface stream. The amount of groundwater right is based on the size of the surface area where each landowner gets a corresponding amount of the available water. Once adjudicated, the maximum amount of the water right is set, but the right can be decreased if the total amount of available water decreases as is likely during a drought. Landowners may sue others for encroaching upon their groundwater rights, and water pumped for use on the overlying land takes preference over water pumped for use off the land.
The EPA was worried that the groundwater system would be vulnerable to contamination from fecal matter.
The point of the rule was to keep microbial pathogens out of public water sources. Other rules in the United States include: Reasonable Use Rule American Rule : This rule does not guarantee the landowner a set amount of water, but allows unlimited extraction as long as the result does not unreasonably damage other wells or the aquifer system.
Usually this rule gives great weight to historical uses and prevents new uses that interfere with the prior use. Groundwater scrutiny upon real estate property transactions in the US: In the US, upon commercial real estate property transactions both groundwater and soil are the subjects of scrutiny.
For brownfields sites formerly contaminated sites that have been remediated , Phase I Environmental Site Assessments are typically prepared, to investigate and disclose potential pollution issues. This bill ensures that India's groundwater is a public resource, and is not to be exploited by companies through privatization of water. The National Water Framework Bill allows for everyone to access clean drinking water, of the right to clean drinking water under Article 21 of 'Right to Life' in India's Constitution.
The bill indicates a want for the states of India to have full control of groundwater contained in aquifers. The Easement Act gives landowners priority over surface and groundwater that is on their land and allows them to give or take as much as they want as long as the water is on their land.
