"Revolutionary Ultrasound Technology Eliminates Persistent Toxins from Groundwater"

Researchers at The Ohio State University have conducted experiments to explore the potential of ultrasound in degrading per- and poly-fluoroalkyl substances (PFAS), also known as "forever chemicals," in contaminated groundwater. The study found that ultrasound can effectively degrade smaller PFAS compounds, which are typically more challenging to treat using other methods. Ultrasound works by emitting low-frequency sound waves that create cavitation bubbles, generating heat that breaks down the stable carbon-fluorine bonds in PFAS. While this method is energy-intensive, it may be a valuable technology for protecting groundwater from PFAS contamination. The research suggests that ultrasound should be considered for future treatment technology development and combined-treatment approaches.
