In Flint, elevated levels of lead were found in the city's water supply after the city disconnected from Detroit's water line as a cost-cutting measure and began drawing water from the Flint River in April Gitanjali, a seventh grader, also saw firsthand how complicated it can be to test water for lead by watching her parents, Bharathi Rao and Ram Rao, try to test the water in their Lone Tree, Colo.
The website featured an article on new technologies used to detect hazardous substances, which Gitanjali figured she could adapt to detect lead. Gitanjali reached out to her parents, both engineers, her teachers and experts at local colleges and universities for help. There was no real expectation that she would necessarily finish, but the journey itself would be the learning experience. It turned out she had a lot more determination. Gitanjali spent months trying to convince local high schools and colleges to give her lab time to continue her experiment.
Most of the spills and failures were made there.
When Gitanjali was named one of 10 finalists in the Discovery Education 3M Young Scientist Challenge earlier this year, she was able to partner with a 3M scientist to help develop her innovation. The result is Tethysa sensor-based device deed to detect lead in water faster than other techniques currently on the market. The device utilizes carbon nanotube sensors —- similar to the technology Gitanjali saw on the MIT website —- to detect lead.
It can then send the to a smartphone. Gitanjali presented Tethys to a panel of judges this week in a live competition at the 3M Innovation Center in St. Paul, Minn. Brian Barnhart, an Illinois school superintendent and one of the seven 3M judges.
The woman whom Gitanjali said inspired her to pursue science and follow her passion to develop the lead testing kit believes Gitanjali can do it. Gitanjali plans to invest most of her 3M prize money back into her project to make it commercially available. It was frustrating the first couple of times, but towards the end, everything started coming together.
