  • Straightforward monitoring of uranium in drinking water

    Determining trace levels of uranium in drinking and mineral water by inductively coupled plasma mass spectroscopy (ICP-MS) requires expensive analytical instrumentation. In contrast, adsorptive cathodic stripping voltammetry (AdCSV) using Metrohm’s 797 VA Computrace is a straightforward, much less expensive alternative allowing measurements with superior sensitivity. ...

  • 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 ...

  • Sophisticated monitoring array to address mystery of uranium plume

    Scientists have been puzzled for years about why uranium contamination in groundwater continues to exceed drinking water standards in an area located at the south end of the Hanford Site. The Department of Energy wants answers to why the uranium persists. Now, an innovative system has been installed for field experiments to better understand this complex site and to support future cleanup ...

  • USGS report details uranium resources and potential effects of uranium mining near Grand Canyon

    As part of the Department of the Interior’s evaluation of whether to segregate nearly 1 million acres of federal lands near the Grand Canyon from new uranium claims, the United States Geological Survey today released a report on uranium resources and uranium mining impacts in the area. The studies contained in the report looked at uranium found in breccia pipe deposits and explored the ...

  • Drinking water wells 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 ...

  • Don’t drink the water – Thousands in Canada can’t drink their water

    A new report from the Council of Canadians reveals that as of January there were 1,838 drinking water advisories in effect across Canada, warning people not to drink their water straight from the tap. The report, On Notice for a Drinking Water Crisis is the first in many years to document the drinking water advisories (DWA) across Canada. On Notice reveals that there were ...

  • New Mexicans challenge Nuclear Regulatory Commission over leach uranium mine

    For the first time in history, the Nuclear Regulatory Commission, NRC, will be challenged in federal appeals court for its approval of a source materials license for an in situ leach uranium mine. The Navajo communities of Crownpoint and Church Rock, New Mexico will fight the Nuclear Regulatory Commission and the permitted company, Hydro Resources, Inc., demanding that they stay off Navajo ...

  • South African mine finds way of removing uranium from groundwater

    Acid mine drainage is one of the world's biggest environmental problems besides global warming. The national nuclear regulator has confirmed uranium contamination in drinking and agricultural water from gold mining activities in South Africa. Currently, the water quality and pollution into our water resources is a bigger health risk than HIV/AIDs.A test trial done with a organic medium developed ...

  • Study: Two major U.S. aquifers contaminated by natural uranium

    Nearly 2 million people throughout the Great Plains and California live above aquifer sites contaminated with natural uranium that is mobilized by human-contributed nitrate, according to a study from the University of Nebraska-Lincoln. Data from roughly 275,000 groundwater samples in the High Plains and Central Valley aquifers show that many Americans live less than two-thirds of a mile from ...

  • Clarks nears permanent solution to safe drinking water

    It's been 12 years since the central Nebraska village of Clarks learned their water contained dangerous levels of uranium. Now, after years of failed attempts to fix it, they're finally one big step closer to a permanent solution. State agencies found the high uranium levels in 2000. "We had over 200 parts per billion, which was the highest in the state," Clarks Mayor Jim Kava says. ...

  • German drinking water survey shows up metals in households with children

    Drinking water is a staple in nutrition. Statutory requirements stipulate that drinking water may not prove grounds for adverse health concerns. It must reach all households in impeccable quality. The quality of household drinking water can, however, be poorer than what the water works discharge. Data from the German Environmental Survey for Children (KUS) carried out by the Federal Environment ...

  • EPA Details Results of $100M Federal Effort to Clean up Navajo Uranium Contamination

    The U.S. Environmental Protection Agency announced progress on a coordinated five-year federal investment of more than $100 million to address health risks posed by pervasive uranium contamination on the Navajo Nation. EPA joined five other federal agencies in releasing a report today outlining the results of their Five-Year Plan. Since 2008, EPA has spent more than $50 million to clean up mines, ...

  • U.S. EPA settlements require investigation of uranium contamination on Southwestern tribal lands (AZ, NM)

    This week the U.S. Environmental Protection Agency entered into two enforcement actions, both of which will contribute towards cleaning up uranium contamination at the Navajo Nation and Hopi Reservation. In one settlement, Rio Algom Mining LLC, a subsidiary of Canadian corporation BHP Billiton, has agreed to control releases of radium (a decay product of uranium) from the Quivira Mine Site, near ...

  • WEF, USGS will sponsor a congressional briefing on the health impacts of private drinking water wells

    The Water Environment Federation (WEF), in cooperation with the U.S. Geological Survey’s (USGS) National Water Quality Assessment Program, will sponsor a congressional briefing to discuss new findings about the quality of our nation’s private drinking water wells. “The Quality of Our Nation’s Private Drinking Water Wells: Are Current Contaminant Levels Above Public Health ...

  • Water footprint of energy

    As Japan’s nuclear power plant emergency has highlighted, water is needed in copious quantities to generate energy. To mark World Water Day, Sandra Postel (National Geographic) considers the huge water footprint of energy generation. According to USGS, thermal power plants (fuelled by coal, oil, natural gas or uranium) account for 49% of water withdrawn. We don’t think much about ...

  • Study finds contaminants in California public-water supplies

    Nearly one-fifth of the raw groundwater used for public drinking water systems in California contains excessive levels of potentially toxic contaminants, according to a decade-long U.S. Geological Survey study that provides one of the first comprehensive looks at the health of California's public water supply and groundwater. One of the surprises in the study of 11,000 public supply wells ...
