Indian Institute of Science (IISc) researchers have developed a novel remediation process for removing heavy metal contaminants such as arsenic from groundwater.

According to IISc, 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.

“In every technology that exists, you can take out arsenic and provide clean water. However, after you remove the arsenic, you must do something about it so that it doesn’t re-enter the environment, and that aspect is not given due consideration in the existing methods. Our process was designed to solve this problem,” said Yagnaseni Roy, assistant professor at the Centre for Sustainable Technologies (CST), whose lab has developed the method.
