Thanks to an all-out cleanup campaign, the coal tar sludge
spilled from an overturned truck has flowed only 1.5 km down the
Dasha River in north China in 42 hours, officials said
yesterday.
The sludge was 52 km away from a downstream reservoir in Fuping
County, Hebei Province at 5?AM Sunday, said
officials with the local environmental protection bureau.
An overloaded truck carrying 80 tons -- the initial figure given
by officials was 60 tons -- of coal tar overturned in Fanzhi
County, Shanxi Province at 5 PM on June 12, and
spilled part of its load into the Dasha River, which originates in
Shanxi and flows 80 km to Fuping.
The polluted part of the river has turned brown and smells
strongly even from tens of meters away.
Cleanup workers have built 51 temporary dams along the river to
halt the spill's movement in an effort to minimize the threat to
the Wangkuai Reservoir, which is the drinking water source for
Hebei's 10 million residents and also a standby for the Beijing 2008 Olympic Games.
Fuping's cleanup workers succeeded in building a major dam 370
meters long,?five meters high and 20 meters wide on Saturday
morning. The structure can hold 200,000 cubic meters of water.
Fifty-three pumps have removed 1,700 tons of polluted water
since the dam was built.
The local governments of Fanzhi and Fuping are making every
effort to prevent the pollution from entering the reservoir. Over
100 dredging machines and 100,000 people in Hebei have been
mobilized to help build dams and conduits to slow down the sludge
flow.
Activated carbon, cotton quilts and sponge material have been
placed in the river to absorb the pollutant.
