  • EPA proposes the west troy contaminated aquifer site in Ohio for superfund national priorities list

    The U.S. Environmental Protection Agency today proposed adding the West Troy Contaminated Aquifer in Troy, Ohio, to the National Priorities List of Superfund sites. Superfund is the federal program that investigates and cleans up the most complex, uncontrolled or abandoned hazardous waste sites in the country. The city of Troy operates two well fields along a 1.25-mile segment of the Great Miami ...

    The importance of groundwater monitoring

    Groundwater monitoring is an essential element in any environmental information system. Based upon validated groundwater monitoring data, information is derived on which decisions can be made. Constant monitoring provides the necessary data input for your smart environment and is basically the basis of the decision making process concerning spatial planning and climate change adaptation. As in ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Encouraging results in evaluating groundwater contaminants

    The widespread use of pesticides across the United States has been in practice for decades, with little knowledge of the long-term effects on the nation’s groundwater. The results of a new study show that samples taken from over 300 wells across the US have not retained a high concentration of pesticide contamination. The news is a result of a decadal long study to assess the extent of the ...

  • Scientists suggest alternative source of arsenic contamination

    New research contradicts previous findings that arsenic contamination — an environmental crisis that affects more than 60 million people in the Bengal Basin — in groundwater may result from arsenic coming from man-made ponds, suggesting instead that it originates in sediments in aquifers. Groundwater ...

  • Milford, Ohio aquifer site proposed to be added to superfund national priorities list (OH)

    U.S. Environmental Protection Agency Region 5 announced today that a contaminated aquifer in Milford, Ohio, is one of nine hazardous waste sites proposed to be added to the Superfund section of the National Priorities List. Superfund is the federal program that investigates and cleans up the most complex, uncontrolled or abandoned hazardous waste sites in the country. There are a total of 1,343 ...

  • Potential of hydraulic fracturing fluids escaping to aquifers subject of new paper in Groundwater

    A recently published scientific paper offers a numerical study of the potential for fluids related to hydraulic fracturing to escape into usable aquifers via nearby abandoned wells. The article was published in National Ground Water Association’s flagship technical journal, Groundwater®. Titled “Influence of Hydraulic Fracturing on Overlying Aquifers in the Presence of Leaky ...

  • Shale gas extraction linked to water contamination

    A new study suggests shale gas extraction leads to methane contamination of underground water sources and calls for thorough surveys of methane levels at extraction sites. The study presents a timely insight into a relatively under-researched area of science that will help support decisions on the future of shale gas exploration. Shale gas, or natural gas extracted from sedimentary rocks ...

  • Studies reveal why drinking water wells are vulnerable to contamination

    New USGS groundwater studies explain what, when, and how contaminants may reach public-supply wells. All wells are not equally vulnerable to contamination because of differences in three factors: the general chemistry of the aquifer, groundwater age, and direct paths within aquifer systems that allow water and contaminants to reach a well. More than 100 million people in the United States receive ...

  • 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 ...

  • EPA orders Dona Ana county and Las Cruces to clean drinking water aquifer

    The U.S. Environmental Protection Agency (EPA) recently issued an order to Doña Ana County and the City of Las Cruces to clean a contaminated ground water aquifer under the city. The aquifer has been used by the City of Las Cruces for drinking water and poses an imminent and substantial danger to anyone who drinks from it. The city and county will be required to build a system that will ...

  • Drinking water of 41m Americans contaminated with pharmaceuticals

    An investigation by the Associated Press (AP) has revealed that the drinking water of at least 41 million people in the United States is contaminated with pharmaceutical drugs. It has long been known that drugs are not wholly absorbed or broken down by the human body. Significant amounts of any medication taken eventually pass out of the body, primarily through the urine. 'People think that if ...

  • Fear at the tap: Uranium contaminates water in the West

    In a trailer park tucked among irrigated orchards that help make California's San Joaquin Valley the richest farm region in the world, 16-year-old Giselle Alvarez, one of the few English-speakers in the community of farmworkers, puzzles over the notices posted on front doors: There's a danger in their drinking water. Uranium, the notices warn, tests at a level considered unsafe by federal and ...

  • Fertilisers linked to contaminated drinking water in Evros, Greece

    In a new study, samples of drinking water from the north-east of Greece have been found to exceed European limits for nitrates, sulphates and phosphates - chemicals that are linked to health problems such as reproductive disorders and cancer. The research has produced a map of the Evros area showing the location of 64 water sampling sites and found that pollution levels are highest in areas with ...
