  • UNESCO publishes first world map of underground transboundary aquifers

    UNESCO is publishing the first-ever world map of shared aquifers to coincide with the submission to the General Assembly of the United Nations on 27 October of a draft Convention on Transboundary Aquifers. Almost 96% of the planet’s freshwater resources are to be found in underground aquifers, most of which straddle national boundaries. Despite its strategic importance, no global inventory of ...

  • Pesticide pollution slow to reach groundwater

    Underground water aquifers are a significant source of drinking water. In a recent study, French researchers found that pesticides applied to crops can take many years to sink down through the ground and reach groundwater. This means that they may still be entering aquifers, even after agricultural application has stopped. Groundwater is found underground in absorbent layers of rock. ...

  • Idaho aquifer decline could hinder radioactive monitoring

    A continued drop in underground water levels could make it more difficult to monitor the movement of radioactive contamination in an aquifer below an eastern Idaho nuclear facility, scientists say. Researchers with the U.S. Geological Survey in a 36-page report released Monday said the Eastern Snake River Plain Aquifer level has dropped below ...

  • Predicting the fate of underground carbon

    A team of researchers at the Massachusetts Institute of Technology has developed a new modeling methodology for determining the capacity and assessing the risks of leakage of potential underground carbon-dioxide reservoirs. One strategy for mitigating greenhouse gases is to inject compressed carbon dioxide into natural aquifers made of permeable rock soaked with brackish salt water. Carbon ...

  • California pledges changes in protecting underground water

    California has proposed closing by October up to 140 oil-field wells that state regulators had allowed to inject into federally protected drinking water aquifers, state officials said. The deadline is part of a broad plan the state sent the U.S. Environmental Protection Agency last week for bringing state regulation of oil and gas operations back into compliance with federal safe-drinking water ...

  • Runoff research promotes healthier aquifers

    Where rain falls can influence the quality of surface water before it enters underground reservoirs, some of which provide water that eventually comes out of our taps. That's one conclusion from a collaborative study by the Agricultural Research Service (ARS) and the University of Arizona (UA). The ARS and UA scientists are investigating how urban landscapes influence storm runoff and water ...

  • Satellite measurement of permanent loss to California groundwater source

    Researchers used satellite data to measure water volume changes due to groundwater variation in the aquifer, to show California’s Central Valley aquifer, the major source of groundwater in the region, suffered permanent loss of capacity during the drought experienced in the area from 2012 to 2015. California’s Central Valley aquifer, the major source of groundwater in the region, ...

  • EPA Designates Mahomet Aquifer as `Sole Source` of Drinking Water in East-Central Illinois

    The U.S. Environmental Protection Agency today announced a decision to designate a portion of the Mahomet Aquifer system as a sole source aquifer. More than half of the population in east-central Illinois relies on the Mahomet Aquifer system as a source of drinking water. The Safe Drinking Water Act gives EPA authority to designate all or part of an aquifer as a "sole source" if contamination of ...

  • California authorizes oilfield dumping into protected aquifers

    Regulators in California, the country's third-largest oil-producing state, have authorized oil companies to inject production fluids and waste into what are now federally protected aquifers more than 2,500 times, risking contamination of underground water supplies that could be used for drinking water or irrigation, state records show. While some of the permits go back decades, an Associated ...

  • Africa may struggle to extract groundwater, experts say

    Vast groundwater resources have been revealed in Africa by the first continent-wide quantitative maps. But the resources may not be easily accessible because of political and technical challenges and costs, say experts. The new groundwater maps, published last month (19 April) in Environmental Research Letters, are based on an extensive review of available maps, publications and data. They show ...

  • Shell fined for polluting UK groundwater

    Shell UK Oil Products Ltd has been fined GBP 18000 by Grimsby Magistrates’ Court for polluting the groundwaters close to its Toothill Petrol Filling Station at Yarborough Road, Grimsby. The cost of cleaning up the underground contamination, which has been paid by Shell to Anglian Water, is estimated to be about GBP 5 million, the court was told on Wednesday (25 June 2008). The company ...

  • Too soon to tap Namibia`s groundwater find, experts say

    The extraction of the much needed water from a large underground aquifer in northern Namibia may need to wait for further studies, officials have warned at a water investment conference. The aquifer, discovered in July, may contain enough water to sustain about one million people living in the area for 400 years at ...

  • New Columbia River water rights under review

    An agreement that could result in new rights to Columbia River water is now available for public review. Under the proposal, irrigators will help pay for water conservation projects that in turn will allow the Washington Department of Ecology to issue new water rights from the Columbia River. The Washington Department of Ecology and the Columbia-Snake River Irrigators Association are proposing ...

  • U.S. EPA Seeks Public Comment on Mahomet Aquifer Designation
