A schoolgirl aged 11 has been honoured as “America’s top young scientist” for inventing a quick, low-cost test to detect lead-contaminated water.
Gitanjali Rao was selected from 10 finalists who had spent three months collaborating with scientists to develop their ideas.
Gitanjali’s invention was inspired by the scandal in Flint, Michigan, where officials are facing over water contamination in 2014-15, she told Business Insider.
But Gitanjali’s portable invention – named Tethys, after the Greek goddess for fresh water – allows a sensor linked to a mobile app to give an accurate, almost immediate analysis via a mobile app.
“If you take a shower in contaminated water, you do get rashes and that can easily be studied by an epidemiologist,” she told Business Insider.
