China's Yellow River pollution rises
The famous Yellow River in China, which is the main water supply for millions of people in northern China, has found to have been heavily polluted by industrial waste and is deemed unsafe for anyone to use.
The Yellow River is the second longest in China and discharge from factories has increased in recent years and water levels have dropped due to industrial and residential growth.
The Yellow River Conservancy Committee said 33.8 percent of the river's water sampled registered worse than level 5, meaning it's unfit for drinking, aquaculture, industrial use and even agriculture, according to criteria used by the United Nations Environmental Program.
A 2007 survey covered more than 8,384 miles of the river, which flows from western Qinghai province across China into the Bohai sea, and its tributaries, a notice posted on the committee's Web site Saturday said.
Only 16.1 percent of the river samples reached level 1 or 2 — water considered safe for household use.
Industry and manufacturing made up 70 percent of the discharge into the river, the notice said, with 23 percent coming from households and 6.4 percent from other sources. The notice did not identify specific pollutants.
The results showed pollution has gotten slightly worse since 2006, when 31 percent of the water in the river was poorer than a level 5, according to an earlier survey.
Most of the industries in that region have not been monitored for pollutants, and they are in a way protected as they provide many jobs for workers. The river is treated as a dumping site and a sewage channel
