What is healthy drinking water?
There are currently three authoritative and representative international standards for drinking water quality:
- WHO’s Guidelines for Drinking Water Quality,
- EC’s Drinking Water Directive, and
- USEPA’s National Drinking Water Regulations.
These three standards are the basis for most national or regional drinking water standards. The standards assert drinking water should be sterile and free of toxic and hazardous substances, contain minerals required for human health, and have high permeability and solubility.
How can we ensure healthy drinking water?
Drinking water must be sterilized to ensure safety. The aim of drinking water sterilization is to kill or inactivate pathogenic microorganisms. Standard methods include sterilization with chlorine, chloramines, ozone, and ultraviolet light.
The smell of disinfectant in tap water currently indicates to people that their water is sterile; however, this smell is often the result of harmful chemical by-products, such as chloroform, dichloroacetic acid, nitrile chloride, bromate, formaldehyde, and chlorite. Chemicals do not need to be used in the purification process at all.
