Standards set for mineral water

THE new quality standards for China's natural mineral water will take effect next month with a stricter control on the amount of disinfectant, bacteria and metals allowed.

The new standards, for the first time, will limit the amount of bromate, a carcinogenic byproduct of a common disinfectant used in mineral water, to 0.01 milligrams per liter, Sanya Morning Post reported today. That is in line with the World Health Organization's guidelines for drinking water.

The bromate limit for tap water was already set at 0.01 milligrams per liter in 2007. Quality watchdogs found bromate exceeding that level in 13 types of mineral water in a nationwide check last year.

The regulations require the source and type of mineral water on its label. It also set limits on the amount of three specific microorganisms.

Some manufacturers may need to spend hundreds of thousands of yuan to upgrade their equipment to meet the new standard on bromate.
