A much-needed update to the existing standards for drinking water, as well as
13 relevant inspection methods, will be officially implemented on July 1,
sources with Ministry of Health and National Bureau of Standards said.
The number of monitoring indicators will increase from 35 to 106 under the
new standards, which were designed to comprehensively improve drinking water
Earlier this week, Taihu Lake near Wuxi, a city in East China's Jiangsu
Province, suffered a massive outbreak of algae, which left millions of people
with a severely contaminated water supply.
But the water crisis, which
experts believe will last for several months, is not an isolated case.

Jiangsu Province, carries away the water he bought after lining up for
seven hours. He had earlier lined up for 12 hours just to buy clean water.
In 2005, a toxic spill in the Songhua River seriously affected drinking water
for four days in Harbin, an urban center at China's northern frontier.

Water pollution is also a major concern in other parts of the country.
Existing drinking water standards were issued in 1985, years before
large-scale industrialization projects flourished in the country, boosting local
economies while simultaneously polluting drinking water sources.
The contamination emerged as a national public health issue in the 1990s, as
did nationwide discussions on how to amend the existing standards.
The revised regulations were initially scheduled to come into force on June
1, 2005, but they were not even released until a year and a half later, in
Wang Zhansheng, a retired professor at the Chinese Academy of Water Supply
and Drainage, said the country's drinking water standards lag behind
international norms by at least 20 years.
The current standards include only two indicators of organic substances -
none for algae toxins - and exclude a number of key contaminants, such as
nitrites and bromates, Wang said.
Consequently, the vast majority of poisonous substances in drinking water are
somehow legally considered safe, he said.
Public health authorities' work in establishing drinking water norms and
standards is not a static one, "because as changes occur in drinking-water
supply practice, in technologies and in materials available ... so health
priorities and responses to them will also change," the third and current
edition of the World Health Organization (WHO)'s guidelines for drinking water
An unnamed senior researcher with the department of water environment at the
China institute of water resources and hydropower research considers the new
standards a sign of progress, but thinks much more remains to be done.
"The government has invested lots of money in improving drinking water
quality, but the results have been less than rewarding," she told China Daily.
For example, more than 6 billion yuan ($785 million) has been earmarked for
the cleaning up of Dianchi Lake in Kunming, capital of Yunnan, where the once
cleanest of all waters has fallen victim to a year after year of industrial
But the investments underachieved, she said.
While claiming that human activity is the root cause of water degradation,
the researcher said an update to the standards must accompany detailed
inspection measures as well as procedures to ensure conservation and protection
of water sources, without which authorities will only scratch the surface.
Ultimately, the amended drinking water standards should be a new beginning
rather than the endpoint.
In the future, "legislation should go hand-in-hand with law enforcement," she
