Some 78.9 percent of China's surface water was deemed "good quality" by the environment authorities  as of November, an increase of 2.6 percentage points on last year and a result which Chinese analysts cited as evidence of an improving overall environment across the country.   

China has a water quality ranking system: from best I to worst V. Levels I-III accounted for 78.9 of all surface water, according to data from the Ministry of Ecology and Environment. 

Level I-III means water is directly drinkable or drinkable after processing, according to national standards; while level V water is unusable and unsuitable for human contact. 

Ma Jun, director of the Beijing-based Institute of Public and Environmental Affairs, told the Global Times that the increasing percentage of drinkable water showed that efforts  at addressing water pollution have yielded results in China. 

"Improvement in water quality also generates benefits like a more active water ecosystem and higher biodiversity, as well as an overall environment more hospitable for human residence," Ma said. 

In 2015, China launched a 10-pronged campaign against water pollution including regulations, legal and administrative responsibilities. 

A designated official, usually local Party chief, was assigned responsibility to tackle water pollution.  

Water pollution is more difficult to address than air pollution, Ma noted. "Even if the polluter is controlled, pollutants in water are more difficult to dissolve, not to mention restoring the waterbed soil where contaminants accumulate," he said. 

And curbing the pollution of underground water costs more and takes longer than surface, Ma said. 

More than half of China's underground water has been polluted while about 80 percent of shallow underground water is undrinkable, according to media reports.
