A Virginia high school student is bringing fresh attention to one of today’s most widespread water concerns: microplastics in drinking water. Mia Heller, an 18-year-old student at Kettle Run High School who also attends Mountain Vista Governor’s School, developed a prototype filtration system that uses ferrofluid, a magnetic oil, rather than traditional filter membranes. In her testing, the system removed 95.52% of microplastics from water and recovered 87.15% of the ferrofluid for reuse. The design works by mixing ferrofluid with contaminated water so it can bind to tiny plastic particles. A magnetic field then separates the ferrofluid and attached microplastics from the water. Heller’s prototype is about the size of a bag of flour and is designed to filter roughly one liter at a time. Her project was inspired by local contamination concerns in Virginia, including PFAS and microplastics, as well as the cost and maintenance demands of household filtration systems. At the 2025 Regeneron International Science and Engineering Fair, she received a special award from the Patent and Trademark Office Society for her environmental engineering work. Microplastics have been detected in waterways, drinking water, ecosystems, and human tissues, though researchers are still studying their long-term health effects. For Indigenous communities, rural households, and others facing water access challenges, emerging filtration ideas like this are part of a wider conversation about safe water, environmental health, and practical technology. Heller’s system is still a prototype and will need independent testing, safety review, and further development before any real-world use. Key questions remain, including how captured microplastics would be safely handled and whether ferrofluid can be fully contained.
