IIT Bhubaneswar Develops 'ArsenSafe', a Hand-Held Device to Detect Arsenic in Water

On June 11, 2026, the Indian Institute of Technology (IIT) Bhubaneswar announced that its researchers have built a compact, portable hand-held device to detect arsenic in drinking water. Named 'ArsenSafe', the device was developed by the Sensors and Spectroscopy Research Group in the School of Electrical and Computer Sciences, led by Sayan Dey, through a start-up incubated at the institute's Research and Entrepreneurship Park.

What makes the device stand out is that it can test water for arsenic without needing a laboratory, special chemicals or trained technicians. It is designed for fast, low-cost, on-site testing, combining nanotechnology with machine learning to read results. The institute said the current prototype has reached a high level of technical readiness and has already been tested on water samples from the IIT campus and nearby areas. Government agencies, public health departments, water-treatment providers, industries, NGOs and even individual households could use it.

The achievement matters because arsenic contamination of groundwater is a serious and long-standing public-health problem in several parts of India. Arsenic is a toxic element that can seep into underground water naturally. Drinking arsenic-laced water over many years can cause skin problems, nerve damage and various cancers. Affected regions include parts of the Gangetic plains, where millions of people depend on borewells and hand pumps for daily water.

Until now, testing for arsenic usually meant collecting samples and sending them to distant laboratories, which is slow and expensive and leaves many rural areas unchecked. A cheap, portable device that gives quick results on the spot could allow far wider and more frequent monitoring, helping authorities identify unsafe sources early and protect public health. It also fits with national goals of providing safe drinking water to every household.

For aspirants, this is a strong example of an Indian science and technology achievement with direct social benefit. Remember the device name 'ArsenSafe', the developing institute IIT Bhubaneswar, and the blend of nanotechnology and machine learning. The wider issue of arsenic and fluoride contamination in groundwater is a recurring theme in geography, environment and science-and-technology sections.
