Natural Processes Can Limit Spread of Arsenic in Water, Says Study

October 10, 2011

Study has shown that deep sediments can grab the arsenic and take it out of circulation—a finding that may help to keep wells safe elsewhere, including in the United States. The study, led by researchers at Columbia University’s Department of Earth and Environmental Engineering and the Lamont-Doherty Earth Observatory, appears in the current online edition of the journal.
New Technologies Reduce Exposure of Bangladeshi Villagers to Arsenic in Groundwater

January 05, 2005

Well diggers in Araihazar, Bangladesh will soon be able to take advantage of a cell phone-based data system, developed at the Lamont-Doherty Earth Observatory with support from the Earth Institute at Columbia University, to target safe groundwater aquifers for installing new wells that are not tainted with arsenic. Using a new needle-sampler (also developed at the Earth Institute), they will also be able to test whether the water is safe during drilling and before a well is actually installed.
