arsenic contamination

Professor Thalappil Pradeep's research group at IIT Madras discovered affordable and sustainable nanomaterials that can remove impurities — like arsenic (primarily), manganese, uranium and iron — from groundwater and produce affordable clean water in rural areas.

IIT Roorkee professor Abhijit Maiti and his team have developed a simple and affordable technology to remove arsenic and other heavy metals to purify water. He explains how it works.

This filter stands to help a total of 22 lakh people across India at risk of being affected by arsenic-contaminated water.

In 2013, a group of researchers at Indian Institute of Technology, Madras (IIT-M) developed an affordable nano technology-based water purifier. The aim behind the purifier was to provide safe drinking water without any microbial and chemical impurities, and to fight the problem of arsenic contamination that leads to many health hazards. It will now be used all across India.

Itchy skin lesions, changes in skin colour, hardening and thickening of skin into nodules - these were some of the afflictions suffered by the villagers due to arsenic contamination of their drinking water sources. But read how this brave village fought back against this scourge, with even a 95-year old pitching in very actively!
