A process and apparatus to remove and breakdown volatile organic compounds from drinking water, groundwater, wastewater, frack water and air exhaust. The process entails filling a tank, chamber, pipe, or column with ozone-containing gas, introducing into this ozone-containing gas-filled tank, chamber, pipe or column, very small droplets of water, contaminated with volatile organic compounds which then volatilize out from the water and break down in the ozone gas thereby improving the water quality and associated air quality. The current invention has been shown to achieve more than 99% combined removal efficiency. The process can also be used to treat air streams containing volatile organic compounds. To increase efficiency, ozone is introduced where the atomized particles are smallest. Three configurations utilizing said process include upward and downward spray of contaminated water into ozone and pumping through openings in an enclosure to a reaction chamber filled with ozone-containing gas.
