BEIJING An outbreak of blue algae in a Chinese
reservoir has left nearly 25,000 people without water and
100,000 others with reduced supplies, state media said on
Wednesday of the latest in a series of water pollution scares.
The algae, in the northeastern city of Changchun, was
likely caused by farm fertilizers and abnormally hot and dry
weather, the official China Daily reported.
The local government had started collecting the algae using
nets and boats and was trucking in water to residents in
Changchun's Luyuan district where supplies have been suspended,
the newspaper added. Other Changchun residents had had water
pressure reduced, the Beijing Youth Daily said, showing
pictures of fluorescent green-looking water in the reservoir.
Water supplies to millions of residents have been affected
in a series of algae outbreaks across the country in recent
On July 4, water supplies to 200,000 people in Shuyang
county, Jiangsu province, were halted for more than 40 hours
after ammonia and nitrogen were found in a local river, state
In late May, a major outbreak in China's third biggest lake
cut off water supplies to over 2 million residents of Wuxi
city, also in Jiangsu.
Algae blooms develop in water that is rich in nutrients,
often because of run-off from heavy fertilizer use, industrial
runoff and untreated sewage -- all pollutants in ready supply
in many parts of China.
