  • Jaffna aquifer depleting from overuse

    The single limestone aquifer, which is the main source of freshwater in Sri Lanka's northern Jaffna peninsula, is gradually depleting through overuse, researchers say. "The area suffers from severe groundwater imbalance which might reach crisis proportions in the future," Shanti de Silva, one of two scientists who ...

  • 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 ...

  • Abu Dhabi looks into stormwater aquifer recharge

    The Abu Dhabi City Municipality is investigating the possibility of using stormwater runoff to inject water into coastal aquifers, while at the same time countering the risks of flooding in the city. The municipality is in talks with the Environment Agency – Abu Dhabi (EAD) over the issue, with the city’s drainage collection network set for major investment and expansion this year. ...

  • 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 ...

  • West Bank aquifer endangered by untreated sewage

    An important water source for both Israelis and Palestinians is in danger due to pollution from sewage, a new Israeli governmental report stated. About 2.8 million people, including Palestinians and Israeli settlers, live in the West Bank, but 'due to conflicts and economic problems, the effluents of more than two million people do not go through efficient pollution treatment', the report by the ...

  • High resolution multi-level monitoring for bedrock aquifers

    This presentation describes a comprehensive approach for determining the nature, extent, transport and fate of contaminants at industrial sites on fractured rock, with emphasis on sedimentary rock, referred to as the Discrete Fracture Network (DFN) approach. Development of this DFN approach began at a sandstone site in California in 1997, where the initial version of a method for measuring ...

  • Technical Announcement: Bacteria No Match for Deep Floridan Aquifer

    A first of its kind study has the potential to impact future regulatory decisions on disinfection practices for water prior to its recharge or following its storage in the Floridan Aquifer. The U.S Geological Survey report found that coliform bacteria die off faster in a regional aquifer system ...

  • 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 ...

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

    The U.S. Environmental Protection Agency today proposed approval of a petition to designate a portion of the Mahomet Aquifer system in east-central Illinois as a sole source aquifer. EPA’s public comment period on the proposed designation begins March 13 and closes June 12, 2014. The Safe Drinking Water Act gives EPA authority to designate an aquifer as a sole or principal source of ...

  • Developing Bioaugmentation Cultures for Chloroethene Remediation in Low pH Aquifers

    One of the major limitations for bioremediation of chlorinated ethenes in aquifers with a pH of approximately 6 and below is the perceived need to adjust the pH to the circumneutral range. This is based on numerous studies with Dehalococcoides and mixed cultures containing Dehalococcoides that indicate a steep reduction or cessation in cDCE and VC reduction to ethene at pH levels below 6. ...

  • 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 ...
