  • Arsenic Illegally Released into California’s Groundwater

    The Environmental Protection Agency (EPA) has fined a natural-gas fired power plant $13,500 for improper management of hazardous waste. According to the EPA, the plant, located in Yuba City, California, generated arsenic from the treatment of wastewater and failed to minimize releases of hazardous waste to the environment. Arsenic occurs naturally in the local groundwater, which the plant uses in ...

  • Ridding rice plantations of arsenic from contaminated groundwater

    Genetically engineered rice plants that resist the uptake of toxic metals could boost production and ease the shortage of this staple crop in Asia, India and Bangladesh, where irrigation with contaminated groundwater has created soils with toxic levels of arsenic. More than 80 percent of the world’s population depends on rice as a staple food, but production is dropping in the rice paddies of ...


  • Lehigh University professor receives Astellas Award for arsenic groundwater remediation efforts

    Arup K. SenGupta, Ph.D., a professor of civil, environmental and chemical engineering at Lehigh University in Bethlehem, Pa., has been chosen to receive a 2009 Astellas USA Foundation Award. The award, administered by the American Chemical Society, is given to individuals who have made significant scientific research contributions that improve public health through their work in the chemical and ...

  • Geologists studying groundwater arsenic levels in India empower Bengali women, children

    A Kansas State University geologist and graduate student are finding that the most important tools in their fieldwork on groundwater arsenic pollution are women and children armed with pamphlets and testing kits. 'When going into a foreign land, you need the common people's help, support and understanding of the work you are doing,' said Saugata Datta, a K-State assistant professor of geology. ...

  • Identifying areas at risk for arsenic contamination

    The contamination of groundwater with arsenic poses a risk to the health of millions of people, especially in the densely populated river deltas of Southeast Asia. To date, no method has been available for identifying high-risk areas without conducting costly sampling campaigns. Now, Eawag has developed a model that allows vulnerable areas to be pinpointed using existing data on geology and soil ...

  • Arsenic poisoning from drinking water

    A study published in The Lancet this month calculated mortality rates associated with arsenic exposure from drinking water in a Bangladeshi population. Individual-level data was used to determine that 21.4% of all deaths and 23.5% of deaths associated with chronic disease in this population could be attributed to arsenic exposure. Millions of people worldwide are chronically exposed to arsenic ...

  • Arsenic Leaches into Iowa Water Supply

    Arsenic has numerous forms, one of which is arsenite. When arsenic is described as harmful, the specific type of arsenic being referred to is arsenite. It is the most common form of arsenic found in drinking water.   According to the Centers for Disease Control and Prevention (CDC), ingesting small amounts of arsenite can cause nausea, vomiting, decreased production of red and white blood ...

  • Arsenic-free water for rural India

    High levels of arsenic in the groundwater in areas of northeast India and Bangladesh are a recognised public health problem. However, the Isolux Technologies Division of MEL Chemicals, Inc. teamed up with an Indian engineering firm in 2009 to supply 39 arsenic treatment systems customised to the requirements of rural Indian villages. Water supply in rural northeast areas of India and neighbouring ...

  • Cow dung a detox for arsenic sludge

    Bangladeshi scientists have found in cow dung an efficient agent to treat the toxic sludge that is generated by the removal of naturally-occurring arsenic in groundwater. "Microorganisms present in cow dung volatilise arsenic in the sludge," says Mohammad Azizur Rahman, research scientist at the geosciences centre of ...

  • 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 ...

  • Occurrence of arsenic a reminder of the importance of testing well water

    The occurrence of arsenic in some well water in Pennsylvania is a reminder that private well owners should test their water regularly, the National Ground Water Association said today. “NGWA recommends that private well owners test their water annually for bacteria, nitrate, and anything of local concern, the latter of which could include arsenic for some Pennsylvanians,” said NGWA ...

  • Arsenic poisoning stalks India`s gold mines

    Scientists have found high levels of arsenic in the soil and groundwater near a gold mine in the south Indian state of Karnataka, highlighting health hazards associated with mining the precious metal.

  • Salmonella treatment option is validated with automated arsenic analyzer

    TraceDetect’s automated arsenic analyzer, SafeGuard, quickly validated a salmonella treatment option that allowed City of Alamosa (CO) water operators to return the drinking water supply system to acceptable levels.The City of Alamosa faced a salmonella outbreak in the water supply earlier this year. The most viable option for quickly fixing the problem was to superchlorinate the water. Although ...


  • Indian arsenic clean-up `working well`

    A new chemical-free method to remove arsenic from water is working well in pilot plants in India, scientists report. The method, developed by a team of European and Indian scientists, was tested in six plants set up to supply safe arsenic-free water to Kasimpore village in India's West Bengal state, one of the most arsenic-contaminated sites in the world. An estimated 140 million people in Asia ...
