OZONE EFFECTS ON CONTAMINANTS IN POTABLE WATER (PART II)

In part two of this series, we list down more contaminants that can be present in potable water, their possible ill effects in humans and effects of ozone treatment.

Many of these contaminants are used as pesticides, and find their way into ground water. Removal of these contaminants from water is easily facilitated by ozone.

Other pharmaceutical compounds are not listed here (EDCs - Endocrine Disruptive Compounds). These compounds also do get into the ground water in an around these industries.

Such a long lists of chemicals and ozone’s effective removal of most of them proves the role ozone can play in keeping our potable water safe for human consumption.
