  • 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 ...

  • 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 ...

  • Natural processes can limit spread of arsenic in water, says study

    Many people in Bangladesh and other parts of Asia have been poisoned by drinking groundwater laced with arsenic—not introduced by humans, but leached naturally from sediments, and now being tapped by shallow drinking wells. In recent years, to avoid the problem, deeper wells have been sunk 500 feet or more to purer waters—but fears have remained that when deep water is pumped out, ...
