Eleven-year-old Gitanjali Rao became concerned about lead in drinking water two years ago, when she learned of the crisis in Flint, Michigan. And it’s not just Flint, says the student from the Denver suburb of Lone Tree, approximately 5,000 water systems in the U.S. have problems with lead contamination.
The seventh grader at STEM School Highlands Ranch told Colorado Matters that troubling statistic was on her mind when she heard of the Discovery Education 3M Young Scientist Challenge, a national competition for middle schoolers to find innovative solutions to everyday problems. This month Rao won that competition, and a $25,000 prize, for a lead-detection device she invented.
Her device is called Thethys, named for the Greek goddess of fresh water. “It includes three main parts,” she says. “A core device, a housing processor with a Bluetooth extension, a 9 volt battery, and a slot to enter a disposable cartridge. And ot all connects to a Smartphone.
