For decades, contaminated groundwater posed a major environmental challenge, especially at industrial and government sites. In the late 1990s, however, an innovative idea changed how these pollutants could be removed. Inspired by science, curiosity, and a desire to protect nature, NASA engineer Jacqueline Quinn helped develop a technology that continues to make a lasting impact on environmental cleanup, as per a report by National Inventors Hall of Fame.
How Did Curiosity Shape Jacqueline Quinn's Career?
Sometimes, a simple question can lead to a remarkable discovery. "'I wonder if you could do this.' It’s such a wonderful phrase and a great way to start the day," said National Inventors Hall of Fame Inductee Jacqueline Quinn. "You have to see if your 'I wonder' statement propels you into thinking a different way or looking at a problem differently."
That mindset became the foundation of a career devoted to science, engineering and environmental protection.
According to the National Inventors Hall of Fame, Quinn was born on July 19, 1967, in Athens, Georgia, where science was part of everyday life. Both of her parents were science educators. Her mother taught biology, human anatomy and chemistry, while her father specialized in early childhood science education at the university level.
Growing up, she spent countless hours exploring nature and visiting her father's laboratory. Those early experiences nurtured a curiosity that would later define her professional journey.
"When I look at the opportunities I had and what I was eventually going to become, I really didn’t have any other option than to go into science, because I had such great role models," she shared in an interview with the National Inventors Hall of Fame. "Being raised with a family that always wanted to be out experiencing the wonders of nature started it off."
Her passion for STEM eventually led her to the Georgia Institute of Technology, where she earned a bachelor's degree in civil engineering in 1989. Soon afterward, she joined NASA's Kennedy Space Center, initially working on the space shuttle program.
Quinn described the experience as "an awe-inspiring adventure." But while working on space exploration, another passion quietly took shape. She became increasingly interested in environmental engineering and how science and technology could be used to protect natural resources.
While continuing her work at NASA, she pursued higher education at the University of Central Florida. She earned a master's degree in environmental engineering in 1994 before completing her doctorate in 1999, strengthening the scientific foundation that would soon lead to one of her most significant inventions, as per a report by National Inventors Hall of Fame.
What Made EZVI a Breakthrough in Groundwater Cleanup?
In the late 1990s, Quinn joined researchers at the University of Central Florida to tackle a difficult environmental problem. The team focused on chlorinated solvent contaminants that NASA had previously used to degrease rocket engine parts. These substances, known as Dense Non-Aqueous Phase Liquids (DNAPLs), sink into the ground and can contaminate freshwater supplies if left untreated.
At the time, the standard cleanup process required contaminated groundwater to be pumped out, treated above ground and then pumped back underground. The method worked, but it was slow and resource-intensive.
Determined to find a better solution, Quinn and her colleagues created emulsified zero-valent iron, better known as EZVI.
How Does EZVI Clean Contaminated Groundwater?
The technology developed by Quinn and her research team took a very different approach from traditional cleanup methods.
Instead of removing contaminated groundwater from the earth, EZVI works underground where the pollution already exists.
"Our vision was to take the reactants and encapsulate them within an oil bubble," Quinn said. "If you go by the old adage that ‘like likes like,’ what we’re trying to do is we’re trying to encapsulate the reactants in something that we know the contaminant is attracted to."
According to information shared by NASA and the National Inventors Hall of Fame, EZVI uses nanoscale zero-valent iron particles enclosed within a biodegradable water-in-oil emulsion. Once injected into contaminated groundwater, the emulsion behaves like a sponge, attracting harmful chlorinated solvents into the oil droplets. Inside the emulsion, the contaminants react with the iron particles and break down into far less harmful byproducts.
The breakthrough eliminated the need to excavate contaminated soil or pump polluted groundwater to the surface for treatment. As a result, cleanup projects required less time while producing fewer toxic byproducts. The system also proved to be cost competitive, making it practical for a wide range of environmental cleanup projects.
The technology has since been used to treat contaminated groundwater at government facilities, manufacturing plants producing dyes, chemicals, pharmaceuticals, adhesives, aerosols and paint, as well as dry-cleaning businesses, leather tanning operations, and metal cleaning and degreasing facilities.
Reflecting on the invention's success, Quinn said, "EZVI stands out as one of NASA's most widely licensed technologies to date,” Quinn said. “While NASA is often associated with the realms of space and airspace, one of our most licensed technologies operates quite literally beneath our feet."
The impact of the invention was recognized in 2005 when Quinn and her team received both the NASA Invention of the Year and the NASA Commercial Invention of the Year awards for EZVI.
Why Does Quinn Continue Inspiring Future Innovators?
Quinn's contributions did not stop with environmental cleanup. She later served as the project manager for NASA's PRIME-1 and VIPER MSOLO lunar missions while continuing to encourage young people to pursue careers in science and engineering. Through her work with Camp Invention®, she hopes to inspire future innovators to ask questions, explore ideas and solve real-world problems.
Her message remains rooted in the same curiosity that shaped her own career. That simple habit of asking questions eventually led to an invention that changed environmental remediation.
From her childhood surrounded by science educators to her work at NASA and the University of Central Florida, Quinn consistently looked for better ways to solve complex problems. Rather than accepting slow and conventional cleanup methods, she helped pioneer a nanotechnology capable of treating dangerous groundwater contamination directly where it existed.
Today, EZVI remains one of NASA's most successful licensed environmental technologies, demonstrating that innovations developed for one challenge can create benefits far beyond their original purpose.
As highlighted by the National Inventors Hall of Fame, Quinn's career reflects how curiosity, persistence and scientific thinking can produce solutions that protect both people and the environment. Her work continues to stand as an example of how asking one simple question can lead to discoveries with lasting global impact.
