KELYDRA WELCKER – Created a Water Filtration System
Kelydra Welcker was only in 7th grade when she figured out a simple test for ammonium perfluorooctanoate, a chemical that was polluting the local waters of the Ohio River where she lived, just 7 miles downstream from a DuPont plant. Then, operating out of a trailer behind her house, Welcker devised a way to remove the Teflon surfactant from the water by combining granular activated carbon and a pair of electrodes. With some help from the local utility company and DuPont, Welcker, now in college, hopes to implement her desktop unit on a community-wide scale.
