Moved by Flint Water Crisis, 11-Year-Old Scientist Invents Lead-Detecting Device

An 11-year-old girl was given a top award after inventing "Tethys," a sensor that detects lead levels in water.

Gitanjali Rao of Lone Tree, Colorado won the 2017 Discovery Education 3M Young Scientist Challenge and a $25,000 prize for the innovation, which she said was inspired by the water crisis in Flint, Michigan.


"I started following the Flint water crisis two years ago when I was nine," Rao told PEOPLE. "And I was surprised that there wasn't a fast, reliable process for testing water for lead."

Rao also pointed out to Reuters that lead contamination is not just an issue in Flint, but in "over 5,000 water systems in the U.S. alone."

She noted that "thousands of adults and children [are] exposed to the harmful effects of lead in water. So it's a pretty big deal out there today."

So how does the device work? "Tethys, the Greek goddess of fresh water, is a lead detection tool," she explained to the news service. "What you do is first dip a disposable cartridge, which can easily be removed and attached to the core device in the water you wish to test. Once you do that, that's basically the manual part. Then you just pull out an app on your phone and check your status and it looks like the water in this container is safe. So that's just very simple, about like a 10 to 15 second process."

Gitanjali said she has always had an interest in science.

"I've always been interested in science because it's all about providing real world ways to solve problems in the world," she told PEOPLE. .

The young inventor plans to put her prize money to her college fund. "I'd like to go to MIT," she said, "and study epidemiology or genetics." She also wants to improve her device to make it ready for public use.

Flint's water troubles began in April 2014, when an unelected state official switched the city's main water supply from Lake Huron to the Flint River to save money. The highly corrosive river water caused old pipes to degrade and leach lead into the water system. The water crisis has been linked to dangerous lead exposure in Flint's population as well as an outbreak of Legionnaires' disease that killed at least 12 people.

While the city's water quality continues to improve, federal regulators still recommend that residents do not drink unfiltered tap water.

Her Stand-Up Paddleboard Is a Platform for Campaigning Against Plastic Pollution

Lizzie Carr was navigating a stretch of the Hudson River north of Yonkers, New York, recently when she spotted it—a hunk of plastic so large and out of place that she was momentarily at a loss to describe it.

Scientists Study Ice Shelf by Listening to Its Changing Sounds

By Marlene Cimons

Researchers monitoring vibrations from Antarctica's Ross Ice Shelf were flabbergasted not long ago to hear something unexpected—the ice was "singing" to them. "We were stunned by a rich variety of time-varying tones that make up this newly described sort of signal," said Rick Aster, professor of geosciences at Colorado State University, one of the scientists involved in the study.

'Go Out and Vote' Patagonia Endorses Candidates For First Time in Its History

Outdoor brand Patagonia is endorsing candidates for the first time in its history in an effort to protect the country's at-risk public lands and waters.

The civic-minded retailer is backing two Democrats in two crucial Senate races: the re-election of Sen. Jon Tester of Montana; and Rep. Jacky Rosen, who is trying to unseat Republican Sen. Dean Heller in Nevada.

Leaked Trump Administration Memo: Keep Public in Dark About How Endangered Species Decisions Are Made

In a Trump administration memorandum leaked to the Center for Biological Diversity, the U.S. Fish and Wildlife Service is directing its staff to withhold, or delay releasing, certain public records about how the Endangered Species Act is carried out. That includes records where the advice of career wildlife scientists may be overridden by political appointees in the Trump administration.

Dirty Diapers Could Be Recycled Into Fabrics, Furniture Under P&G Joint Venture

Disposal diapers can take an estimated 500 years to decompose. That means if Henry VIII wore disposables, they'd probably still be around today.

Although throwaway nappies are undoubtedly convenient, these mostly-synthetic items cause never-ending steams of waste that will take centuries to disappear.

6,000 Evacuated After Tibet Landslide

Six thousand people have been evacuated after a landslide in Tibet Wednesday blocked a river that flows downstream into India, creating a lake that could cause major flooding in the subcontinent once the debris is cleared, The Associated Press reported.

Chinese emergency officials announced the evacuations Thursday. The landslide impacted a village in Menling County, but no one was killed or injured, Chinese officials said.

Carbon Capture: What We Don’t Talk About When We Talk About Climate Change

By Daniel Ross

The latest Intergovernmental Panel on Climate Change (IPCC) report lays out a rather grim set of observations, predictions and warnings. Perhaps the biggest takeaway? That the world cannot warm more than 1.5 degrees Celsius (1.5°C) over pre-industrial levels without significant impacts.
