Scientists discover new PFAS cleanup method

A study published in the Journal of Hazardous Materials Letters shows a new method of breaking up per- and polyfluoroalkyl substances (PFAS) into small harmless compounds using hydrogen and ultraviolet light.

Led by chemical engineering and environmental scientists from the University of California Riverside, the team adds hydrogen into contaminated water, then exposes the water to high-energy, short-wavelength UV light.

The hydrogen in the contaminated water polarizes water molecules, making them more reactive. The UV light, on the other hand, speeds up the chemical reactions that result in PFAS destruction.

Compared to water treatment methods that use UV light, the study’s patent-pending process destroys strong fluorine-to-carbon chemical bonds nearly 100 percent and guarantees zero undesirable or harmful by-products or impurities.
