Water pollution challenges serious
Print Edition
CHINA still faces serious water pollution challenges, despite progress over the past few years.
Of the 972 national monitoring stations, 9.2 percent posted surface water quality below grade 5 last year, said Chen Changzhi, vice chairman of the National People’s Congress Standing Committee, on Thursday in a report delivered to the top legislature.
The figure was 17 percentage points lower than the level in 2005, marking significant improvement, Chen said.
China uses six classifications for water quality. Grade 1 is the best. Water no worse than grade 3 can be used for drinking, although sometimes treatment is required. Water worse than grade 5 is too polluted for any purpose.
According to the report, 63.2 percent of the samples were ranked levels 1 to 3 last year, up 22 percent from 2005.
Chen warned of safety risks for the country’s drinking water resources, citing the top legislature’s inspection results on the enforcement of the Water Pollution Prevention and Control Law from May to June.
Drinking water sources in 278, or 84.5 percent, of the 329 cities under inspection nationwide meet national standards, according to the report.
Inspectors found potential polluters, including farms, households and public facilities, near drinking water sources.
The team suggested local governments standardize demarcation of boundaries at drinking water sources, enhance monitoring and tackle illegal sewage systems.
