If ozone comes into contact with water vapor during storms it forms hydrogen peroxide. This is why plants flourish better with rainwater than with irrigation water. This is natures way of cleaning the environment. Natural ozone concentrations can vary between .01 ppm to .05 ppm, depending on geographic location, altitude and season. The cycle of oxygen and ozone is just like the cycle of water in nature.
Ozone is created by waterfalls and oceans surf.
This accounts for the calm and the relaxed feeling enjoyed while at the beach or in the mountains. This is sometimes referred to as activated oxygen, allotropic, triatomic form of oxygen or pure air. Being an unstable gas, ozone's life span is about 20 minutes, depending on the temperature. After completing its job, it reverts back to oxygen. This means ozone has to be produced on site.
