China makes headway against water pollution
March 22,2017   By:Xinhua
BEIJING, March 22, 2017 -- Dianchi Lake in southwest China has hopes of restoring its lost splendor after 30-odd years of severe pollution.
Water quality in the lake, the largest on the Yunnan-Guizhou Plateau, was once deemed "inferior to Grade V," the worst in China's water quality grading system and "too polluted for any purpose."
Decades of breakneck growth left much of China's water seriously contaminated by factory waste and agricultural fertilizer. Last year was the first time the water in the 300-square km lake was clean enough to be used for agriculture since 1985, a testament to what China has achieved.
The story of the Dianchi Lake is encouraging and nationwide, things are gradually getting better.
The proportion of monitored surface water reaching Grade III or above rose by 1.8 percentage points to 67.8 percent in 2016, surpassing the 66.5-percent target, Zhang Bo, an official with the Ministry of Environmental Protection (MEP), said ahead of World Water Day on March 22.
The share of water "inferior to Grade V" fell by 1.1 percentage points to 8.6 percent, Zhang told a press conference on Monday.
Only water at or above Grade III can be used for drinking, although treatment may be required.
The work behind the seemingly small improvement was anything but easy, exemplified by the clean-up of Dianchi Lake, a victim of reckless industrial development, surging domestic sewage and once regarded as the filthiest body of water in China.
The city of Kunming, where the lake is located, has now built 22 sewage disposal plants. A total of 35 major rivers flowing into the lake have been treated, and intensive livestock and poultry farming in the vicinity banned.
China has said "no more" to economic growth at the price of the environment, but it takes time and hard work to reverse decades of damage. More than 70 percent of the water in seven major river valleys, including the Yangtze and Yellow rivers, should reach Grade III or better by 2020, according to a 2015 action plan.
In December, China began to appoint "river chiefs" with responsibilities which include resource protection, pollution prevention and control, and ecological restoration. Their performance will be assessed and they will be held accountable for environmental damage in bodies of water under their supervision.
