The Yellow River Conservancy Committee said in a bulletin released last Thursday that it monitored the mainstream of the Yellow River and its tributaries last year, with the combined length totaling 13,492.7 km, and found 4,557.6 km, or 33.8 percent of the waterways monitored, to have polluted water classified as type-five negative.
The Yellow River Conservancy Committee is an organization affiliated to the Ministry of Water Resources and has its headquarters in Zhengzhou, capital of central China's Henan Province. It is assigned with the mission to overseeing the welfare of the Yellow River system. Only 2,174 km of the waterways, or 16.1 percent of the river sections monitored, were said to have water quality classified as types one and two, both standards suitable for drinking.
The bulletin also showed that the river system had an increase of 18.9 percent in rainfall last year in comparison with that of 2006, but received more pollution too: waste and sewage water discharged into the river system totaled 4.29 billion tonnes last year. Industrial sector was blamed as the No.1 polluter, followed by living sewage contributed by urbanites living along the river system and the service trade.
In 2006, the organization monitored 12,510.8 km of the Yellow River system, of which, 31.1 percent were found to have type-five negative water. And 4.26 billion tonnes of waste and sewage water was discharged in the Yellow River system in that same year.
