Researchers at the Centre for Sustainable Technologies (CST), Indian Institute of Science (IISc) have developed a novel remediation process for removing heavy metal contaminants such as arsenic from groundwater. The three-step method, which is patent-pending, also ensures that the removed heavy metals are disposed of in an environment-friendly and sustainable manner, instead of sending untreated heavy metal-rich sludge to landfills from where they can potentially re-enter groundwater.
