Groundwater is an essential source of drinking water across the country. However, heavy metal contamination in groundwater presents a significant health hazard. Researchers at the Indian Institute of Science (IISc) have developed a nanomaterial-based solution that can effectively reduce the presence of heavy metals like chromium in groundwater.

The team includes researchers from the Center for Sustainable Technologies (CST), Department of Civil Engineering (CiE), and Department of Instrumentation and Applied Physics (IAP). The study is published in the Journal of Water Process Engineering.

Chromium typically enters soil and groundwater through effluents from industries such as leather tanning, electroplating, and textile manufacturing. "Heavy metals enter the environment because of urbanization and certain mismanagement by industries," says Prathima Basavaraju, Ph.D. student at CST and lead author of the study.
